Aluminium / Aluminum 6101 alloy does not react to heat treatment. However, heat treatment can be done by annealing and aging.
Aluminium / Aluminum 6101 alloy can be cold worked in the aged or annealed conditions.
Aluminium / Aluminum 6101 alloy is annealed at 413°C (775°F) for 3 h followed by controlled cooling at 10 to 260°C (50 to 500°F) per hour, and cooling in air. Stress relief annealing process can also be performed after cold working at 344°C (650°F) followed by cooling in air.
Aluminium / Aluminum 6101 alloy can be aged at different temperatures and times based on the finished temper. For example, T6 can be aged at 177°C (350°F) for 20 h, T61 can be aged at 227°C (440°F) for 6 h, and T63 can be aged at 194°C (380°F) for 19 h followed by cooling in air.
Aluminium / Aluminum 6101 alloy can be hardened by cold working and aging.
is used in electrical bus bar conductor applications for enclosed bus electrical installations.
