4043 aluminium 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 6.0%) 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.[7][8][9][10][11]

Element Percentage (%)

Copper (Cu) 0.30
Manganese (Mn) 0.05
Magnesium (Mg) 0.05
Zinc (Zn) 0.10
Titanium (Ti) 0.20
Beryllium (Be) 0.0003
