Short Description:

Cadmium-free silver brazing alloys

Silver base brazing filler metals, with excellent processing property, optimal melting temperature , good wetting and seam-forming property, high joint strength and ductility, good corrosion resistance, have been widely used in brazing mild steel, stainless steel, Structure Steel, refractory alloys, copper and its alloys , cemented carbides and Kovar alloys, etc. In order to improve performance and satisfy the increasingly serious technical requirement , the silver base filler metal we usually use is added Sn,Ni,Si,Mn,In,Ga to form Ag-Cu-Zn-Sn, Ag-Cu-Zn-Ni, Ag-Cu-Zn-Mn,Ag-Cu-Zn-X(Ga,Sn,In,Ni) series product and so on.
