Product Description

ERCuSn-A (Phosphor Bronze) filler metals contain about 5 percent tin and up to 0.35 percent 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 liquidus and solidus. 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 can be used to weld bronze and brass. They also can be used to weld copper if the presence of tin in the weld metal is not objectionable.

When gas tungsten arc welding with ERCuSn-A filler metals, preheating is desirable. Welding is done in the flat position only.

Applications:

Suitable for welding of copper materials,for example copper and tin bronzes,especially used for joining of copper zinc alloys and steels. Also suitable for repair welding of cast bronzes.For large work pieces preheating is recommended.For multilayer welding on steel,pulsed arc welding is recommended-also appropriate for oven soldering.
