Description
TAURUS 4043 ALUMINIUM MIG WIRES
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.
SOME FEATURES AND BENEFITS
- The silicon content gives improved wetting action .
- Lowers crack sensitivity.
- Used for welding and brazing alloys .
APPLICATIONS
Applications in the construction and automotive industry.
MATERIALS TO BE WELDED
TAURUS ALUMINIUM MIG 4043 wire is used to weld most aluminium alloys containing up to 7% silicon and can be used for welding wrought to cast aluminium materials.
