4043 aluminium alloy

Aluminium silicon alloy

4043 aluminium alloy^[1]^[2]^[3] is a wrought aluminium alloy with good corrosion resistance typically used as filler material^[4]^[5] for welding of aluminium parts. It contains high amounts of silicon (between 4.5 and 6%) and trace amounts of other metals.^[6] It is grey in appearance and is sold as either welding wire or welding rod for TIG/MIG processes.

Chemical composition

Aluminium is the remainder.^[4]^[7]^[8]^[9]^[10]
