Trade Mark：RBCuZn-A/S**3:

 Composition: Cu*9Sn0.9Si0.1Fe0.8 Zn:Rem

Description: S**3 is a silicon-free tin-brass welding wire, which can be completely avoided during welding due to the
A brittle compound is formed at the interface between the welding material and the base material steel, and the risk of embrittlement of the joint is obtained, and satisfactory mechanical properties are obtained.
Application: Suitable for flame brazing, induction brazing and furnace brazing of steel, copper and copper alloys, nickel and nickel alloys and stainless steel where corrosion resistance requirements are not important.
used on gas welding, brazing of cooper  Melting point is about **0℃ 

I) Welding copper or copper alloy to connect them;

II) The most widest purpose is welding the parts between metals（such as bushing,the sealing surface of low-pressure valve etc.) & the parts resistant to seawater corrosion( such as screw propeller) due to its abrasive resistance & corrosion resistance)

III) It is widely used in brazing steel,hard alloy tools,etc.
