4043 - ALUMINIUM MIG WELDING WIRE

DESCRIPTION:

4043 is an aluminum/silicon filler metal designed for welding heat treatable base metals and is a common choice for welding 6061.  4043 offers good fluidity and less crack sensitivity than 5356 when welding 6000 series base metals.  It is often used to for repair welding aluminum/silicon cast alloys such as grades 353/A356.
