All about aluminum

Aluminum is manufactured from bauxite which is abundantly found in the Earth’s crust. Bauxite is mined from regions along the equator and goes through a process in which the alumina is extracted. It is then smelted and mixed with other alloying elements and cast into aluminum billets or logs. This cast aluminum is the raw material used for the aluminum extrusion process.

Aluminum alloys vary based on the composition of alloying elements that are added to the aluminum. The typical alloying elements are copper, magnesium, manganese, silicon, tin and zinc.

  • Non-combustible
  • Cold strength / ductility at low temperatures
  • Reflective

ALMAG’s available aluminum extrusion alloys

Aluminum Alloy6063

A multi-purpose alloy. Good corrosion resistance, finishing response, weldability, machinability, formability. Applications include windows, doors, curtain walls, signs, furniture, medium-strength frames, decorative trim, heatsinks and boats.

Aluminum Alloy6360

Great balance of extrudability and mechanical properties. Provides a good surface finish, readily welded, good corrosion resistance and forms well. Ideal for complex shapes in applications other than structural.

Aluminum Alloy6063 T65

Bridges the gap between 6063 and 6005A & 6061 with higher mechanical properties than 6063 T6. Tighter tolerances possible over 6005A & 6061. Good finishing response.

Aluminum Alloy6005A

Excellent extrudability and strength, low impact resistance, good finishing response, weldability, formability, and machinability. A high-strength alloy. More extrudable than 6061 and 6351. Effective applications include antennas, towers and machined parts.

Aluminum Alloy 6463

Produces a bright, mirror-like, high quality finish, good machinability and formability. Ideal for picture frames, appliance trim, showcase, shower stalls, display systems and light reflectors.

Aluminum Alloy 6061

Excellent strength, corrosion resistance and machinability, poor finishing response, good weldability and formability. A high-strength alloy used in trucks, trailers, towers, machined parts and marine applications.

Aluminum Alloy6351

High strength structural alloy. Provides good fatigue and impact resistance. Used in pipelines, highway barriers, trailers and road vehicles.

Aluminum Alloy3003

3003 is a general-purpose alloy with moderate strength, good workability, and good corrosion resistance. It can be cold worked but not heat treated. 

Aluminum Alloy1050

Good corrosion resistance, weldability, poor machinability, high formability, high electrical and thermal conductivity, non-heat-treatable. Typical applications are architectural and appliance trim and low-pressure tubing for carrying chemicals and foodstuffs.
