De-oxidized Copper Filler Metal

De-oxidized Copper Filler Metal

De-oxidized Copper, ERCu as per AWS A5.7 and SG-CuSn as per DIN 1733, is an unalloyed copper filler metal normally applied for the welding of deoxidized copper and electrolytic tough pitch copper, suitable for welding both in TIG and MIG methods. Thanks to its excellent flowability, it is very ideal for pure copper welding; solid and porous-free welds can be guaranteed.

Phosphor Bronze Filler Metal 2

Phosphor Bronze Filler Metal 2

Phosphor Bronze 2 (ERCuSn-C as per AWS A5.7 & SG-CuSn8 as per DIN 1733) is a copper-tin based welding filler metal containing approx. 8% tin for higher hardness and strength. It can be used to join phosphor bronzes of similar compositions. It is also useful for joining brasses and, in some cases, for welding them to cast iron and carbon steel. The higher tin content results in weld metals of higher hardness, tensile and yield strength.
