Description TAURUS ALUMINIUM MIG 4043 is a 95% aluminium, 5% silicon wire suitable for welding heat treatable base alloys, and more specifically, the 6XXX series. It has a lower melting point and more fluidity than the 5XXX series filler alloys and is preferred by welders because of its favourable operating characteristics. The ER4043 wires are also less sensitive to weld cracking with the 6XXX series base alloys. TAURUS ALUMINIUM MIG 4043 is suitable for spray-arc and pulsed-arc transfer. APPLICATIONS Applications in the construction and automotive industry. MATERIALS TO BE WELDED TAURUS ALUMINIUM MIG 4043 wire is used to weld most alumini-um alloys containing up to 7% silicon and can be used for welding wrought to cast aluminium materials.
