This presentation provides both a conceptual and a practical understanding of how to creatively address product challenges with aluminum extrusions • Advantages of Aluminum and
Aluminum Extrusion - The Extrusion Process
• Key Design Variables - Alloys - Shapes - Fabrication
• Case Examples • Additional Resources
Introduction
7
Aluminum: a material with outstanding physical characteristics Aluminum Extrusion: often the most functional, cost effective and quickest path between function and form – Incredibly versatile, capable of converting
ideas to reality quickly and inexpensively – A near-net shape process for complex forms,
with close tolerances Together, the metal and the process optimize component and product designs!

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
Why Aluminum Extrusions?
Strong Appropriately alloyed and tempered, aluminum can be stronger than some steels, with ultimate tensile strengths as high as 80,000 psi to 90,000 psi or more.
Advantages of Aluminum
9
High Strength-to-Weight Ratio The standard aluminum frame for the 2014 Corvette C7 is over 90 pounds lighter, yet 60% stiffer than the previous steel frame
Corrosion-Resistant Excellent corrosion resistance in a wide variety of environments and contact with a myriad of substances. It develops its own inert aluminum oxide film, which is self-protective, blocking further oxidation.
Advantages of Aluminum
10
Cold Strength • Advantages are not impaired by cold. Aluminum gains
strength and ductility as temperatures are reduced, making it a preferred metal for cryogenic (low-temperature) applications.
• Steel and plastics get brittle when the temperature drops… aluminum gets stronger and tougher!

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.
Advantages of Aluminum
12
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.
Actual feedstock in 2010 contained 53% recycled content.

Advantages of Aluminum Extrusion

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.

Advantages of Aluminum Extrusion
16
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.

Screw bosses
Local thickening
Advantages of Aluminum Extrusion
17
Suitable for a Wide Range of Finishes Aluminum accepts a great variety of finishes, colors and textures (anodize, alodine, wet or powder paint, applique, etc.)
Easy to Fabricate • Designing with aluminum extrusions can eliminate
much fabrication and assembly steps •.Parts can be easily cut, machined, finished, bent,
welded, fabricated and assembled.
Advantages of Aluminum Extrusion
18
Joinable by Various Methods Aluminum extrusions can be joined to other aluminum products or to different materials by all major methods, including adhesive bonding, welding, soldering, brazing, bolts, rivets, clips, clinching and slide-on, snap-together or interlocking joints.
Hinge detail “Christmas tree” for joining with wood or plastic
Screw boss on leg Groove to accept printed circuit cards
Groove for screw or rivet Groove for rubber moulding
Drill groove
Slot for location of nut or bolthead
Screw boss Fluted surface for appearance
Groove to accept printed circuit cards
Dovetail assembly
Snap fit spring assembly
“Heat sink” cooling fin
Patterned surface for appearance
Suitable for easy-to-assemble designs Aluminum extrusions with integral connection points have been widely used for elaborate framing, such as the scaffolding for the Statue of Liberty renovation and the recent repair of the Washington Monument
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
Advantages of Aluminum Extrusion
19
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 modest tool costs, with short lead times
facilitate the use of custom shapes to create a signature design solution with differentiation and enhanced function.

Choices of Alloy, Geometry (or shape), Tolerances and Fabrication offer design flexibility …
• To tailor component performance • To inexpensively incorporate functional details that simplify assemble,
reduce part counts, and enhance utility …but, there are some limitations • Circle Size (the circumscribing circle that the profile could fit through) • Weight/Ft (Too heavy? Too light?) • Shape Constraints – High tongue ratios – Somewhat balanced wall thicknesses – Other

Joining The rapid increase in automoDve aluminum content – and in mulD-‐material soluDons – has led to a dynamic evoluDon in material joining technology. In response, a comprehensive Aluminum Joining Manual, has recently been developed.
Key Design Variables- Fabrication
The manual addresses: • Adhesive Bonding • Beam Welding • Brazing • Mechanical Joining • Resistance Welding • Fusion • Combined Joining • Joining Dissimilar Materials

Case Examples Often, we end up breaking (or at least bending) the “rules” to meet particular product challenges, striving to meet multiple objectives. Yet Aluminum is often costlier* than alternate materials per pound, e.g.:
Assessment q Weight reducDon q Packaging efficiency q Cost reducDon q Build process/ Manufacturability q Serviceability q Quality
Realistic economic comparisons should consider: • Aluminum’s lower density (1/3 that of steel) and offsets from: • Weight reduction, including that of secondary elements • Reduced processing & assembly costs from “designed-in” functionality • Maintenance savings • End-of-life costs/credits

Case Example: Medical

Accuray TomoTherapy System for radiation oncology • Issue – 64 mechanical “leaves”, coupled to a
pneumatic actuator, open and close to deliver the prescribed radiation dosage. Occasional breakage of the machined steel couplings caused machine shut down.
• Objectives - redesign the couplings for improved system up-time - reduce part cost and manufacturing complexity. Existing steel couplings were machined using EDM, requiring multiple manufacturing steps and yielding a relatively high cost
Case Example: Medical
46
• Approach - Replace EDM steel coupling with an aluminum extrusion, 6063 alloy, machined and hard coat anodized - Tweak part design for improved strength and durability - Laser etch identification on each part for traceability
• Results - No failures through 10 million cycle test regimen - “snap fit” assembly cut labor by 30 to 60 minutes per assembly; eliminated a tool used for assembly - Component manufacturing cost cut by nearly 90%; production time cut by 75%
