Alumeco is the leading aluminium Supplier in Scandinavia - having the most extensive stock including a wide range of profiles, bars,
tubes, plates and coils. Our strength is strong standard solutions as well as unique solutions for the individual customer. Alumeco was
founded in 1983 and has since experienced a constant expansion. Alumeco has subsidiaries in several countries.
Mould tools for bumpers, EN AC-5083 is frequently used in the car
industry because of the material’s good mechanical and chemical
properties.
Aluminium propeller: The offshore and shipbuilding industries make high
demands on the material’s corrosion resistance and dimensional stability,
as the finished components are subjected to heavy loads during use.
Injection tools for chair manufacture: This tool in EN AC-5083 usually
stands up to many hours of use.
Milled aluminium component: Precision is crucial when adapting an
EN AC-5083 aluminium component to manufacturing machinery.

Alumeco can supply cast aluminium plates - EN AC 5083 precision milled on both sides with protective foil. Plates can
be supplied in thickness up to 80 mm.

Aluminium alloy 5083 has long been preferred for
the manufacturing of plates that have to meet
high demands. Plates in aluminium alloy 5083
are especially used for mould tools, machine construction,
precision engineering, space industry, aviation industry
and more. All these sectors need the high strength, good
machining properties and seawater resistance provided by
alloy 5083.
Alumeco stocks aluminium alloy EN-AW 5083 plates in standard
dimensions. EN AC-5083, which has the same chemical and anti-
corrosion properties as EN-AW 5083, is available in blocks from
the mill in the following standard dimensions detailed below:
The advantage of EN AC-5083 is that plates in
this alloy can be sawed out in precise dimensions
from a block, because our modern machinery can
saw blocks on all six sides. As a result, we can deliver every
conceivable dimension in thicknesses ranging from 10 to 1,000
mm, up to a maximum width of 1,180 mm and a maximum
length of 3,100 mm. This eliminates waste!
In addition to square plates, we can also offer
short leadtimeson:1)Sawndiscswithamaximum
diameter of 1500 mm (-0/+5 mm) and minimum
diameterof155mm(-0/+5mm).2)Sawnringswithamaximum
outer diameter of 1500 mm (-0/+5 mm) and a minimum
innerdiameterof 160mm (+0/-5mm)and a maximum inner
diameterof1450mm(+0/-5mm). This applies all the way up to
a maximum plate thickness of 400 mm.
Duetothehighcontentofmagnesium(4.5%)and
manganese (0.7%), the alloy is highly corrosion
resistant and also well-suited for welding. As this
product is cast, it has no strip tension caused by rolling,
resulting in plates that are well-suited for machining. Also,
the plates will not warp, making it possible to achieve a high
sawing speed with good tolerances.
The standard material is available with 3.1
certification according to EN 10204:2004, which
specifies the alloy composition. This material is also
available on request with full mechanical test certificates.
The sawing is in full swing. A block usually weighs 5 to 7 tonnes.
Our machinery can also handle the sawing of round plates or disks out of an aluminium block.
