Phos Bronze C GTAW (TIG) Welding Alloy

Phos Bronze C GTAW (TIG) 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

• Designed for welding base metals of steel, cast iron, copper, brass and bronze
• Often used on overlays on cast iron or steel or to join dissimilar metals
• Yields high strength (66,000 psi tensile and 35,000 psi yield) deposits on phos-bronze materials
• The 7%-9% tin content creates greater hardness
• Preheat is generally not required unless welding high copper content base metals
• Typical applications include maintenance, repair and fabrication of bearings, bushings, couplings, gears, housings, propellers, pumps, shafts and valve bodies and seats
• Use with 100% argon or 25%/75% argon/helium shielding gas mixture
• Conforms to ANSI/AWS A5.7 & AMSE SFA A5.7 ERCuSn-C CDA 521
