Description: S221 has a melting point of about 890-905 C, is a special brass wire containing a small amount of tin

and silicon. Tin can improve the fluidity of the wire, and silicon can effectively control the evaporation of zinc and

eliminate the pores, thus obtaining a good weld.Uses: It is suitable for filling materials in brass and copper gas

welding, and is also widely used in brazing steel and cast iron and inlaid carbide tools. It can also be used as

a surfacing material for low pressure valve sealing surfaces and light load wear surfaces.

Welding powder: CJ301, QJ302

Comply with: GB/T9460-2008 Model SCu6810A

Remarks:

1. The welded parts of the weldment and the surface of the welding wire must be carefully cleaned before welding;

2.  before welding, generally preheating to 400~500 C after welding, oxygen-acetylene flame welding must be equipped

with copper gas welding flux;

3.  The welding flame should adopt neutral flame or slight oxidation flame, appropriately reduce the temperature during

welding, increase the welding speed, minimize the residence time of the molten pool at high temperature, and reduce

the evaporation and oxidation of zinc.
