Description:
ER4043 is a common alusi welding wire. The joint metal has good thermal cracking resistance and good mechanical property. The joint metal has different color from base material during anodizing.
Application:
It can be used as filling material for alumal alloy workpiece and castings during argon arc welding and oxygen-acetylene gas welding. Widely used in chemical, food, locomotives, ships, furniture, automobile industry and structural parts and other aluminum alloy welding.
6 series aluminum wire welding, pallet, auto parts, aluminum busbar, bicycle frame, container, cast aluminium die, building templates, fitness equipment.
