high quality aluminum welding wires ER4043

1. This kind of aluminum alloy welding wire used to weld heat-treated parent metal, exactly for 6XXX series alloy. Because it’s less sensitive for hot crack, also used to weld cast materials. Besides, silicon element strengths puddle fluidity, so ER4043 is liked by welding operators. 2.
