ER4043
ER4043 aluminum welding wire is an aluminum alloy welding wire 5% content of Si, aluminum silicon alloy welding wire, has good fluidity. It is used for welding forging and casting materials because of low sensitivity to hot cracking.It is easy to produce brittle Mg2Si in the weld seam during welding, which reduces the plasticity and corrosion resistance of the joint.The welding is beautiful and bright, the arc is stable, the spatter is small, but after anodizing, the color is different from the base metal.
ER4043 aluminum/silicon GMAW (MIG) welding alloy
Designed for welding heat treatable base alloys, specifically 6XXX series alloys
Lower melting point and more fluidity than 5XXX series filler alloys
Low sensitivity to weld cracking with 6XXX series base alloys
Suitable for sustained elevated temperature service, i.e. above 150°F (65°C)
All position, except vertical down welding
Gray (post anodized) color
