Aluminum Vs. Competing Metals

Aluminum Metal Vs Competing Metals Extruded Products

When it comes to being a leading North America extruded aluminum housing company and providing aluminum extrusion profiles services, Getec delivers services for companies across the globe. As aluminum extrusion suppliers, we consistently deliver quality products within our scope of manufacturing. It is our goal to focus on excellence for our customers.

Aluminum Vs. Competing Metals

Property Aluminum Extrusions Roll Formed Steel Copper Extrusions (Deoxided; Low Phosphorus)
Strength (Tensile) Very good mechanical properties Very high mechanical properties Average to low mechanical properties
Density Lightweight; about 1/3 that of copper or steel High density; high pounds per cubic foot About three times heavier than aluminum
Strength to Weight Ratio Very Good Good Low
Corrosion Resistance Excellent; it can be further increased, along with enhanced appearance, through anodizing or other coatings Poor; usually requires protective coatings for corrosion service Excellent
Formability Easily formable and extruded in a wide variety of complex shapes including multi-void hollows. Formable to net shapes, and extrusions provide for the placement of metal where it’s needed Readily formable; thinner cross-sections than aluminum extrusions metal cannot always be located where best used in design Excellent formability and easily extrudable. Formable to net shapes
Electrical Conductivity Excellent; on a pound for pound basis, twice as efficient as copper, used in bus bar and electric connector applications Poor cannot usually be used as an electrical conductor Excellent electrical conductivity
Thermal Conductivity Excellent; ideal for heat exchanger applications Poor cannot usually be used as a heat exchanger Excellent thermal conductivity, second only to silver in industrial applications
Finishing A near limitless array of finishes can be applied including mechanical and chemical prefinishes, anodic coatings, paints and electroplated finishes Protective coatings such as paint finishes are employed along w with electroplated finishes A variety of coatings and platings can be employed
Recyclability High scrap value; routinely reprocessed to generate new extrusions Low scrap value Very high scrap value
Tooling Economics Extrusion tooling is relatively inexpensive. Generally, a simple shape will cost only a few hundred dollars. Short lead times for tooling construction Typical tooling costs are thousands of dollars. Long lead times are required Inexpensive tooling costs for extrusions
Energy Savings Lightweight aluminum extrusions can offer energy savings for transportation vehicles Lifetime energy requirements for wrought steel vehicle components are twice those for aluminum components In transportation vehicles, copper is less energy-efficient than aluminum
Combustibility Noncombustible; does not emit any toxic fumes when exposed to high temperatures Noncombustible; does not emit any toxic fumes when exposed to high temperatures Noncombustible; does not emit any toxic fumes when exposed to high temperatures
