Copper & Copper-Alloys Bare Welding Rods for TIG/MIG Welding
Classification:
- AWS/SFA A5.7 ERCuSn-C (UNS number C52100)
Description & Application:
ERCuSn-C filler metal contains about 8% tin and up to 0.35% phosphorus. The higher tin increases strength and
wear resistance and increases the solidification temperature range during deposition of the weld metal. When gas
tungsten arc welding with ERCuSn-C filler metals, preheating is desirable. Welding is done in the flat position
only.
Shielding Gas:
GMAW: 100% Ar or 75/25 Ar/He
GTAW: 100% Ar/He
