TAURUS TIG SILICON BRONZE is pure copper filler rod deoxodised with 3% silicon for welding a wider range of copper alloys including overlaying of steels and cast irons. TAURUS TIG SILICON BRONZE should be shielded with pure argon but pure helium provides deeper penetration, higher travel speeds and allows reduced preheating.
Applications include plate for chemical plant and moulds, stills and calorifiers, rods and wires for electrical components and tubes for heat exchangers.
General purpose including phosphorous deoxidised copper, silicon bronze, nickel silver and some brasses.
