TAURUS MIG SILICON BRONZE is a pure copper filler wire deoxidised with 3% silicon for welding a wide range of copper alloys including overlaying of steels and cast irons. The wire is optimised for laser brazing.
APPLICATIONS
Applications include plate for chemical plant and moulds, stills and calorifiers, rods and wires for electrical components and tubes for heat exchangers. Also excellent for MIG brazing and laser brazing onto galvanised steel for automotive body panels.
MATERIALS TO BE WELDED
General purpose including phosphorous deoxidised copper, silicon bronze, nickel silver and some brasses.
WELDING POSITIONS
• Downhand • Horizontal flat • Horizontal vertical• Vertical up • Overhead
