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
