1050 aluminum alloy

1050 aluminum alloy is formed by adding a small amount of copper element to pure aluminum, which has excellent forming and processing characteristics, high corrosion resistance, good weldability and electrical conductivity. 

1050 aluminum alloy is widely used in products that do not require high strength, such as chemical instruments, thin plate processing parts, deep drawing or spinning concave vessels, welding parts, heat exchangers, clock surfaces and disks, nameplates, kitchen utensils, decorations, reflective appliances, etc. .

1050 aluminum alloy 【heat treatment process】

Heat treatment specifications:

1) Complete annealing: heating at 390-430°C; depending on the effective thickness of the material, the holding time is 30-120min; cooling with the furnace to 300°C at a speed of 30-50°C/h, and then air-cooling.

2) Rapid annealing: heating at 350-370°C; depending on the effective thickness of the material, the holding time is 30-120min; air or water cooling.

3) Quenching and aging: quenching at 500-510°C, air cooling; artificial aging at 95-105°C, 3h, air-cooling; natural aging at room temperature for 120h
