Fabrication of 1050/1050A aluminium embossed heat shield sheet
Aluminium/aluminum 1050A alloy can be welded using both TIG and MIG methods. The filler that is used is mostly aluminium/aluminum 4043 or 1050 alloy. Annealing of aluminium/aluminum 1050/1050A alloy can be performed at 350°C (662°F). T4 is the commonly used tempering process for this alloy. The alloy is solution heat treated and naturally aged to gain a very stable condition.
