Fabrication and Heat Treatment

Hardening

Aluminium / Aluminum 1060 alloy can be hardened only from cold working. Tempers H18, H16, H14 and H12 are determined based on the amount of cold working imparted to this alloy.

Annealing

Aluminium / Aluminum 1060 alloy can be annealed at 343°C (650°F) and then cooled in air.

Cold Working

Aluminium / Aluminum 1060 has excellent cold working characteristics and conventional methods are used to readily cold work this alloy.

Welding

Standard commercial methods can be used for Aluminium / Aluminum 1060 alloy. The filter rod used in this welding process whenever needed should be of AL 1060. Good results can be obtained from the resistance welding process performed on this alloy through trial and error experimentation.

Forging

Aluminium / Aluminum 1060 alloy can be forged between 510 to 371°C (950 to 700°F).

Forming

Aluminium / Aluminum 1060 alloy can be formed in an excellent manner by hot or cold working with commercial techniques.

Machinability

Aluminium / Aluminum 1060 alloy is rated with fair to poor machinability, especially in the soft temper conditions. The machinability is much improved in the harder (cold worked) tempers. Usage of lubricants and either high-speed steel tooling or carbide are recommended for this alloy. Some of the cutting for this alloy can also be done dry.

Heat Treatment

Aluminium / Aluminum 1060 alloy does not harden by heat treatment and it can be annealed after the cold working process.

Hot Working

Aluminium / Aluminum 1060 alloy can be hot worked between 482 and 260°C (900 and 500°F).

Applications

Aluminium / Aluminum 1060 alloy is widely used in the manufacture of railroad tank cars and chemical equipment.
