RAAJ Bronze – A

Copper & Copper-Alloys Bare Welding Rods for TIG/MIG Welding

Classification:

AWS/SFA A5.7 ERCuSn-A (UNS number C51800)

Description & Application:

ERCuSn-A filler metals contain about five percent tin and up to 0.35% phosphorus added as a deoxidizer. Tin increases wear resistance of the weld metal and slows the rate of solidification by broadening the temperature differential between the liquid solidus and us. This slower solidification increases the tendency to hot shortness. To minimize this effect, the weld pool should be kept small and welding time as short as possible. ERCuSn-A filler metals are used to weld bronze and brass. They are also used to weld copper if the presence of tin in the weld metal is not objectionable.
