Environmental synergies between smelter,

cast house and rolling mill

In recent years, the reduction o greenhouse gases has

become an issue o growing importance to the metallurgi-

cal industry. Using the very latest technologies and exten-

sive synergy eects available along the entire processing

chain, the AMAG group has succeeded in achieving very

low CO2

emissions and energy consumption.

Very low CO2

emissions during

AMAGs ingot production

AMAG casting employs post-consumer material, in-house

scrap and primary aluminium or the production o roll-

ing ingots. Its primary aluminium base is secured by the

participation in the Aluminerie Alouette Inc. smelter in

Canada, which numbers among the most efcient in theworld. Electricity emanating exclusively rom hydropower

sources keeps CO2

emissions at a signifcantly low level.

Manuacturing o aluminium alloys via the recycling route

saves up to 95 per cent o the energy required or primary

production. Moreover, as the latest scrap preparation

methods, melting technologies and casting processes are

applied at the Ranshoen location, sizeable amounts o

correctly sorted post consumer scrap can be employed in

the production o aluminium brazing materials. Both core

alloys and fller materials contain considerable secondary

raw material content.

Resource protection by process optimisation

In addition to the selection o raw materials with regard

to energy consumption and CO2

emissions, AMAG is

constantly working on improvements o its production

processes. Optimized manuacturing parameters and pro-

cessing acilities e.g. or heat treatment, cut energy con-

sumption and thereore CO2

emissions. Innovative urnace

concepts incorporating great exibility and an optimum use

o capacity levels also make a considerable contribution to

resource conservation.

AMAGs enhanced recycling technologies and optimized

processes acilitate energy savings and thus provide a

signifcant reduction in both CO2

emissions and impact on

the atmosphere and water reserves.

Brazing

process

Advantages o aluminium brazing

The use o aluminium alloys in heat exchanger applica-

tions has steadily increased over the last two decades and

because o the continuing drive or lightweight design and

cost reductions, aluminium has virtually replaced copper

and brass.

Manuacturers have derived ull advantage rom the prop-

erties o aluminium brazing material concerning strength,

weight, thermal conductivity, ormability and corrosion

resistance. Thereore brazed aluminium heat exchang-

ers have become quite common in radiators, oil coolers,

condensers, evaporators, intercoolers and air condition-

ing equipment. And this success is directly linked to the

development o joining processes.

History

At the beginning o the 1970s aluminium heat exchangers

were mechanically assembled; then in the middle o this

decade the uxless vacuum brazing (VAC) process was

introduced into large scale production. Subsequently, theimproved, ux-based controlled atmosphere brazing (CAB)

technique developed in the early 1980s, led to a steady

increase in the use o aluminium brazing material or heat

exchanger applications.

VAC-CAB process

As aluminium alloys orm a stable and high melting oxide

flm, all the brazing methods include the Al-oxide layer

penetration step. The uxless vacuum brazing process

(VAC) and the ux based controlled atmosphere brazing

(CAB) overcome this problem by means o two diering

procedures.

In vacuum brazing the fller alloy contains 1.0-2.0% mag-

nesium, which diuses on the surace during the brazing

cycle and then vaporizes at 600C due to low pressure o

10-5 mbar. The Mg-vapour disrupts the oxide layer and thus

enables the fller alloy to ow. This Mg-vapour deposits on

the cold urnace walls during vacuum brazing and must be

regularly removed to ensure efcient urnace operation.

In controlled atmosphere brazing a non corrosive, non

hygroscopic ux is employed to dissolve and break up the

oxide layer beore the fller alloy melts. A Mg-content o

over 0.3% in the molten clad reduces the perormance o

the ux due to the ormation o high melting K-Mg-F-com-

pound. These compounds reduce the viscosity o the liquid

fller and results in poor brazing results.

Aluminium brazing

material production

Complex assemblies can be turned into single unit by just

one pass through a brazing urnace. Aluminium brazing a-

cilitates the joining o parts with a near-eutectic Al-Si fller

alloy, the liquidus temperature which is about 50C lower

than that o the core. In serial heat exchanger productionthe fller alloy is supplied via a thin clad on a core alloy.

Compound Material

Aluminium brazing material is a sophisticated multi layer

compound consisting o a core alloy which provides the

strength and lie cycle requirements o the heat exchanger

and a clad brazing fller. A one-sided protection layer can also

be clad, in order to prevent water-side radiator corrosion.

During brazing, only the clad brazing alloy melts, while the

core alloys remain solid. The design and the applied ma-

terials o the heat exchanger are adjusted to optimize the

brazing result regarding the required post braze mechani-

cal properties as well as the corrosion resistance.

Roll cladding

Today, two basic cladding techniques, roll bonding and

cast cladding, have become established industrially. Roll

cladding is a solid-state welding process, which is used

to join similar and dissimilar aluminium alloys, and repre-

sents the primary method o manuacturing uselage skin

sheet or aircrat, bright products and brazing sheet or

automotive applications. The cladding layers are attached

to the core slab by welding and metallurgical bonding

using hot rolling. The cast cladding technique is based

on a conventional direct chill mould modifed in order to

allow multiple metal streams to be casted into one singlealuminium ingot.

Cladding thickness

AMAGs well established, roll bonding process guarantees

tight cladding thickness tolerances, which are essential or

ensuring stable brazing results. Extremely thin clad layers

o 1.5% can be manuactured, as well as brazing materi-

als with a cladding thickness o 20%.

Tailor made heat

exchanger materials

The development o aluminium alloys to meet the varied re-

quirements o heat exchanger manuacturers has advanced

in step with the growing use o aluminium brazing material.

Optimized material selection involves criteria as there are

ormability, strength, corrosion resistance, atigue resistance

and suitability or brazing.

AMAGs cladding process ensures tight metallurgical bond-

ing o the fller material onto the core ingot and thus top

quality o the brazing material.

AMAG TopClad

Typically, non heat-treatable Al-Mn based alloys o the 3xxx

series are used or the core material o aluminium brazing

compounds.

AMAG TopClad LL (LongLife)

In order to meet the demands or higher strength and

improved corrosion resistance, AMAG developed modifed

3xxx materials which are well known as LongLie alloys.

Special chemistries and thermo-mechanical processingserve to improve the corrosion resistance levels oered by

conventional 3xxx alloys.

AMAG TopClad HS (High strength)

Higher mechanical strength ater brazing can be obtained

by the heat treatable 6xxx alloys as the EN AW-6063

(AlMgSi) or the EN AW-6951 (AlMgSiCu) by means o

solid solution and precipitation hardening. During brazing,

Mg2Si particles are dissolved and the elements are kept in a

solid solution by means o rapid cooling. The strength o the

material is enhanced by small precipitates which are ormed

aterwards at room temperature.

AMAG TopClad UHS (Ultra high strength)

AMAGs speciality in the feld o heat exchanger materi-

als is the adapted EN AW-7020 alloy to which a urther

barrier layer has to be applied in order to prevent diusion

phenomena.

EN-AW 7020 core material belongs to the heat treatable

alloys which in addition to high static strength, is char-

acterised by excellent weldability and high welded seam

strength. The combination o zinc and magnesium results in

heat treatment ability and thus in strengths that ar exceed

those o standard brazing alloys. Parallel to joining during

the brazing process, solution annealing also occurs at braz-

ing temperature. In sot temper AMAG TopClad UHS 7020

achieves an Rp0.2

yield strength o 65 MPa, which

ater brazing can rise to over 140 MPa due to room

temperature ageing.

While in order to achieve optimum strength, the majority

o heat treatable aluminium alloys have to be subjected to

solution annealing within a relatively narrow temperature

range, this does not apply to AMAG TopClad UHS 7020.

The cooling speed ollowing brazing can be varied to a

high degree without aecting subsequent age hardening

at room temperature. AMAG TopClad UHS is an excellent

material or base plates. Due to the hardness o 55 HB in

sot temper the high strength material possesses excel-

lent resistance against mechanical deects in sot temper.

Indeed, AMAG TopClad UHS is a premium solution when-

ever high scratch resistance is required.

AMAG MultiClad UHS (Ultra high strength)

In particular, strength issues mean that the demand or

high-perormance heat exchangers with a reduced volume

and mass either cannot be met by conventional brazing

materials, or only to an insufcient extent. In view o this

problem, AMAG rolling was prompted to develop a high-

strength, multilayer brazing material.

High-strength MultiCladUHS brazing material allows the

production o new and innovative heat exchangers with

the potential to provide sustainable component and design

optimization, and a reduction in material thickness with a

corresponding cut in weight and size.

AMAG has developed a fve-layer compound material con-

sisting o a high-strength EN-AW 7020 core, fller material

and an additional diusion barrier. All standard aluminium-

silicon alloys can be cladded using both vacuum- and

uxing agent-based processes. The material compound

resulting rom the rolling process possesses tight metal-

lurgical bonding.

Corrosion behaviour

o heat exchangers

The corrosion resistance o aluminium heat exchang-

ers depends on the (electro-) chemical interaction o the

entire system, the microstructure o the core material and

environmental actors. The microstructure, which is inu-

enced by the chemical composition and the processing,

has a signifcant impact on the mechanism o corrosion.

The severe environmental conditions to which aluminium

heat exchangers may be exposed have a considerable

eect on lietime. Both internal corrosion due to heat

exchanging agents (e.g. rerigerants and coolants) and

external corrosion relating to the environment (e.g. salt,

water) can cause perorations and leaks.

Pitting Corrosion

Heat exchangers oten suer rom pitting corrosion, as in

the presence o an electrolyte the surace brazing mate-

rial is removed at localized points and this results in the

development o cavities. The primary cause o pitting is a

dierence in the corrosion potential created by an inhomo-

geneity either in or on the material surace.

Waterside Corrosion

Water-side corrosion on the inner side o a tube can be

controlled sufciently through the use o the proper cool-

ing liquid with appropriate inhibitors. When applied to the

core, water-side clad alloys such as EN AW-1050 or

EN AW-7072 can improve internal corrosion resistance.

Air Side Corrosion

All approaches aimed at enhancing the corrosion prop-

erties o aluminium brazing materials are intended to

mitigate the deleterious pitting mechanism into a less

harmul corrosive attack. AMAG rolling has developed

AMAG TopClad LL, which incorporates special chemis-tries with tailored thermo-mechanical processing. This well

designed combination between chemical composition and

the production route considerably improves the corrosion

resistance o these LongLie alloys.

Galvanic Protection

The principle o galvanic protection is commonly applied

with regard to the critical components o the heat ex-

changer: When in contact with an electrolyte, a less no-

ble (anodic) alloy corrodes preerably in comparison with

a noble (cathodic) alloy. Corrosion prevention requires

careul selection o alloy combinations. Depending on the

electro-chemical potentials o the post-brazed materials

in use, the corrosion attack on the single components

can be controlled. Lateral corrosion attack along the precipitate layer

Modifcation o the Microstructure

As grain boundaries represent the path along which cor-

rosion proceeds, elongated grains enhance the LongLie

perormance o the material. The precipitation o Al-Mn-Si

particles adjacent to the core/fller interace has a urther

positive impact on the corrosions resistance. This is

because the precipitate layer has lower corrosion potential

than the residual core and thus acts as a sacrifcial layer.

Material Selection

The electrochemical potentials o heat exchanger materi-

als may indicate the corrosiveness but does not include

the inuence o the microstructure on the corrosion.

Accelerated corrosion tests (SWAAT-Test) allows AMAGto predict the durability o heat exchangers.

Elevated Temperature Strength

A critical material requirement is sufcient strength at

elevated temperatures; especially automotive oil cool-

ers require aluminium heat exchanger material with high

temperature tensile strengths.

Formability Characteristics

The ow curve can be calculated rom the region o

uniorm elongation rom yield strength Rp0.2

to uniorm

elongation Ag

in the stress-elongation curve. In order to

determine the material characteristic values or orming

the orce is related to the actual section area o the speci-

men. The ow stress kis related to the region o plastic

ow and depends on material, temperature, degree o

strain and strain rate. The strain hardening exponent n can

be calculated rom the ow curve; the higher the value o

n and the higher the uniorm elongation, the lower is the

tendency o the material to neck locally. Brazing sheets

do not exhibit the same properties in all directions; the

variation o material properties in dependence o the rolling

direction is called anisotropy r.
