Harris Products Group, 03PHB50, Phos Bronze C TIG Welding Alloy, 7%-9% Tin, ANSI/AWS A5.7, 66,000 psi Tensile

Phos Bronze C TIG (GTAW) copper-tin welding alloy is used to weld copper-tin composition base metals. Also used to weld copper alloys, including brass-to-steel. Conforms to ANSI/AWS A5.7 & AMSE SFA A5.7 ERCuSn-C CDA 521.

Features

• Use with 100% argon or 25%/75% argon/helium shielding gas mixture
• Typical applications include maintenance, repair and fabrication of bearings, bushings, couplings, gears, housings, propellers, pumps, shafts and valve bodies and seats
• Designed for welding base metals of steel, cast iron, copper, brass and bronze
• Conforms to ANSI/AWS A5.7 & AMSE SFA A5.7 ERCuSn-C CDA 521
• The 7%-9% tin content creates greater hardness
• Pre-heat is generally not required unless welding high copper content base metals
