Aluminum - Metal of the Future
Aluminum is the second most commonly used metal in the world, next to steel, of course. The reason is that aluminum has a unique combination of properties that make it ideal for building projects: Lightweight, high strength, excellent malleability, easy fabrication, and superior corrosion resistance.
Aluminum is very often and very easily recycled, making our goal of green building products for the future a little bit easier.
Aluminum is light with a density one-third that of steel.
Aluminum alloys have a great strength-to-weight ratio that is superior to many other alloys. Unlike most grades of steel, aluminum does not become brittle at lower temperatures. Instead, aluminum increases in strength at low temperatures, an attribute unique to aluminum.
- Non-magnetic material
Aluminum is a non-magnetic (actually paramagnetic) material.
Aluminum is easily modified using most machining methods: milling, drilling, cutting, punching, bending, etc. The energy input during machining is lower than other alloys, making aluminum even "greener".
- Corrosion resistance:
Aluminum reacts with oxygen in our air to form an extremely thin layer of oxide. This thin layer is highly dense and provides excellent corrosion protection.
Aluminum has superior malleability to other alloys, an essential for extruded metal. Either hot or cold in temperature, aluminum's malleability allows for easy roll forming and bending.
- Zero toxicity
Aluminum is the third most common element found in the earth's crust, after oxygen and silicon.
