Fabrication and Heat Treatment

Machinability

The aluminium/aluminum 6262 alloy is added with lead and bismuth to improve its machining characteristics. It can be smoothly machined using high-speed or carbide tooling. Oil lubricant is used for heavy cuts.

Forming

The aluminium/aluminum 6262 alloy can be formed using conventional methods.

Welding

The aluminium/aluminum 6262 alloy has good weldability. It can be welded using brazing process.

Heat Treatment

The aluminium/aluminum 6262 alloy is heat treated by annealing and aging.

Cold Working

Cold working capacity of the aluminium/aluminum 6262 alloy is different in many of the common temper conditions. T6511, T6510, T6, and T651 tempers have average cold working capacity. T9 temper has poor cold working capacity.

Annealing

The aluminium/aluminum 6262 alloy is annealed at 538°C (1000°F) for a sufficient period of time followed by quenching in hot water.

Aging

Aging of the aluminium/aluminum 6262 alloy can be performed at 340 to 350°F for 8 to 12 h to obtain different tempers. For example, T6 and T62 tempers are aged for 8 h to form cold formed bar or rod, and for 12 h to form extruded shapes. The T4 and T42 tempers are formed by natural aging at room temperature.

Hardening

The aluminium/aluminum 6262 alloy can be hardened by cold working or by a combination of aging and subsequent cold working.

Applications

The aluminium/aluminum 6262 alloy can be used in manufacturing fittings, nuts, couplings, screw machine products, and camera parts.
