Today’s presentation will introduce you to the properties and processes that will allow you to create unique responses with custom aluminum extrusions Today’s Agenda • An Overview
- Advantages of Aluminum and Aluminum Extrusion
- The Extrusion Process • Key Design Variables - Alloys - Geometry - Fabrication (& Finishing) • Case Examples • Additional Resources
Introduction
With this highly workable material you can create – not choose – shapes that yield functionality and aesthetics, while providing superior cost effectiveness and sustainability.

Aluminum Extrusions are a preferred material for commercial construction due to their unique combination of attributes:
• Lightweight strength • Design flexibility • Longevity, and low maintenance • Sustainability – infinite
recyclability and high recycled content potential
Introduction
Some of the applications for aluminum extrusions in commercial buildings: • Fenestration
• Windows and doors (including hurricane- forced entry– tornado- and blast-resistant)
• Store Fronts & Curtain walls • Energy Management
• Sun shades and louvers • Light shelves • Photovoltaic panel framing,
mounting • Skylights & Canopies
• Sun rooms • Atriums and enclosures • Observatories • Gates & archways

Introduction
Some of the innovative applications for aluminum extrusions in commercial buildings: • Structure
• Bridge decks • Canopies • Space frame systems • Garages and parking covers • Geodesic domes and structures
• Interior elements • Panel systems and cubicles • Elevator cab framing • Light housings & grids • Demountable interior walls • Railing systems • Decorative screens
• And more…
While aluminum extrusions are often a predetermined element in a building product, custom shapes can peak the imagination of designers and architects …

Today’s presentation will introduce you to the properties and processes that will allow you to create unique responses with custom aluminum extrusions Today’s Agenda • An Overview
- Advantages of Aluminum and Aluminum Extrusion
- The Extrusion Process • Key Design Variables - Alloys - Geometry - Fabrication (& Finishing) • Additional Resources
Overview
15
Aluminum Extrusion combines: • a material with outstanding physical
characteristics • a process that is incredibly versatile,
capable of converting ideas to reality quickly and inexpensively, creating near-net shapes for complex forms, with close tolerances
Together, the metal and the process optimize component and product designs!
16
Advantages of Aluminum • Lightweight • Strong • High Strength-to-Weight Ratio • Resilient • Corrosion-Resistant • Heat Conductive • Reflective • Electrically Conductive • Non-Magnetic • Non-Sparking • Non-Combustible • Cold Strength • Fully Recyclable
Advantages of Extrusion
• Tailored performance – put metal where
it is needed
• Suitable for complex, integral shapes,
produced to close tolerances
• Attractive, wide range of finishes
• Virtually seamless
• Easy to fabricate
• Joinable by various methods
• Suitable for easy-assembly designs
• Produced with uniform quality
• Cost Effective
• Short production lead times
Overview
Strong, with high Strength-to-Weight Appropriately alloyed and tempered, aluminum is stronger than some steels, with ultimate tensile strengths as high as 80,000 psi to 90,000 psi or more.
Overview – the material
17
The standard aluminum frame for the 2014 Corvette C7 is over 90 pounds lighter, yet 60% stiffer than the previous steel frame
Corrosion-Resistant Aluminum develops its own inert aluminum oxide film, which is self-protective, blocking further oxidation.
18
Cold Strength • Aluminum is not impaired by cold, gaining
strength and ductility as temperatures are reduced; a preferred metal for cryogenic (low-temperature) applications.
• Steel and plastics get brittle when the temperature drops… aluminum gets stronger and tougher!

Overview – the material
Electrically Conductive Volume for volume, aluminum carries electricity about 62% as well as copper. On a weight basis, aluminum can be twice as conductive as copper, and aluminum is often the most economical choice.

Heat Conductive Conducts – and dissipates - heat better than any other common metal on both a weight and cost basis.
Overview – the material

Sustainable & Fully Recyclable • Can be recycled over and over without
degradation of its innate properties • Recycling requires only 8% of the energy
necessary to produce virgin aluminum • Extrusions can contain as much as 80%,
recycled content. • In 2014, North American extruders will
utilize > 2.5 Billion pounds of scrap!

The Extrusion Process - how are HOLLOW Shapes Extruded?
The PlayDoh flows through the opening between the part of the die that forms the outside diameter and the inside “mandrel” supported by two horizontal supports.
The PlayDoh SEPARATES into two tube halves and “welds” back together due to the pressure needed to make it flow through the annular opening into a tube shape.

24
Produced to Close Tolerances • The ability to hold tight tolerances over the
full extruded lengths are routine and the ability of aluminum extruders to meet even more critical dimensions is keeping pace with advances in technology.
Suitable for Complex, Integral Shapes • Shapes can combine functions that would
otherwise require the production and joining of several different parts, reducing part counts and costs.

25
Accepting a Wide Range of Finishes Aluminum extrusions accept a great variety of finishes, colors and textures (anodize, alodine, wet or powder paint, applique, etc.)
Simplified Fabrication & Assembly • Creative Design with aluminum extrusions
can eliminate fabrication and assembly steps
•.Parts can be easily cut, machined, finished,
bent, welded, fabricated and assembled.
Process Typical Part Tooling Cost ($)
Aluminum Extrusion $500 to $5000
Stampings $5000 and up
Injection Molding $25,000 and up
Die Castings $25,000 and up
Roll Forming $30,000 and up
Overview – the process
26
Cost-effective • The diversity of shapes permitted by the
extrusion process cuts down or eliminates many machining and joining operations.
• Tooling costs are modest in comparison with other processes.
Time-effective • Extrusion’s short lead times facilitate
design iteration and the use of custom shapes to create an effective design solution

Designing in functionality Specific features can be designed into your extrusion to: • enhance joining to other extrusions or
other materials • Facilitate assembly • Provide added functionality, e.g.
heat dissipation • Enhance aesthetics, \etc.

• Painting: a variety of liquid or power resin formulations typically applied electrostatically in either horizontal or vertical paint lines.
55
Key Design Variables - Finishing
• Durability. Most anodized products have an extremely long life span and offer significant economic advantages through maintenance and operating savings.
• Ease of Maintenance. Scars and wear from general use (fabrication, handling, installation, frequent surface cleaning) are virtually nonexistent. Rinsing or mild soap-and-water cleaning usually will restore an anodized surface to its original appearance. Mild abrasive cleaners can be used for more difficult deposits.
• Color Stability. Exterior anodic coatings provide good stability to ultraviolet rays, do not chip or peel, and are easily repeatable.
