Product Description

We are professionally managed company engaged in the fabrication and supplying a wide range of brass welding alloy. These are made from from pure metals of precise chemical specifications as per the varied quality standards. Our collection delivers consistent performance due to its excellent brazing properties. Our range adheres to RoHS standards. These are high demands by our clients belonging to various industries. 

HZ-S221 is a kind of copper and zinc brazing alloy, and available for gaseous flame brazing, high frequency brazing, furnace brazing, resistance welding etc. HZ-S221 has good welding performance, and it is widely used for brazing of copper and copper alloy, steel, copper nickel alloy, gray cast iron, cemented carbide etc. It could replace H62 filler metal and be used as wire of brazing brass. HZ-S221 is a special brass brazing filler metal that contains tin and silicon. While tin improves fluidity, silicon controls evaporation of zinc, and eliminates gas hole to get an excellent welding process. Because of good corrosive and toughness, HZ-S221 is often used by surface welding worn parts of metal, such as bearing valve sealing surface, propeller. HZ-S221 brass wire should work together with copper gas welding flux when oxyacetylene gas brazing.

 

Item Number:HZ-S221

Chemical Composition (%):Cu 59-61, Sn 0.8-1.2, Si 0.15-0.35, Zn Remain,

Melting Point:890-905°C

Recommended Temp.:910-945°C

Advantages and Usage:For brazing copper and copper alloy, steel and cast iron in the method of flame brazing, furnace brazing and induction welding

 

Caution:1.The surface of oil and oxide on the work pieces should be cleansed carefully before brazing .

2. Preheat the work piece to 400 to 500°Cbefore brazing.

3. Matching flux should be used together when brazing.

4.Neutral flame or slight oxidizing flame could be used when flame welding. Appropriate decrease welding temperature, increase welding speed, reduce residence time of molten pool in high temperature to lessen the evaporation and oxidation of zinc.
