ERCuSn brazing wire (Phosphor Bronze) is a copper-tin alloy filler metal used for welding/brazing copper, brass, bronze, and steel, offering high strength, wear/corrosion resistance, good fluidity due to tin, and often containing phosphorus as a deoxidizer, suitable for TIG/MIG with Argon shielding for applications like marine parts, valves, and general repairs.
Key Characteristics:
Composition: Primarily copper and tin, with phosphorus (P) for deoxidation; ERCuSn-A has ~6% Sn, ERCuSn-C ~8% Sn.
Properties: High tensile strength, excellent wear resistance, good corrosion resistance, good fluidity.
Appearance: Golden color (as a copper alloy).
Standards: Meets AWS A5.7 (ERCuSn-A, ERCuSn-C).
Applications:
Joining copper to copper-zinc (brass) alloys and steel.
Repair welding of cast copper and bronze products.
Surfacing (hardfacing) on steel for wear resistance.
Fabrication of valves, gears, bearings, propellers, and housings.
Welding Process:
Shielding Gas: Argon (Ar) or Argon/Helium mixes.
Technique: Suitable for GTAW (TIG) and GMAW (MIG).
Preheat: Recommended for large parts.
Multi-layer: Pulsed arc welding is often used for multi-layer deposits on steel.
Types (ERCuSn-A vs. ERCuSn-C):
ERCuSn-A (Phos Bronze A): ~5-6% Tin, good fluidity, used for general bronze/brass welding.
ERCuSn-C (Phos Bronze C): Higher tin (7-9%), increased hardness, better for harder overlays and specific copper/tin alloys
