Copper Alloy Silicon Bronze Brazing Wire
♦ INTRODUCTION
HUAZHONG HZ-CuSi Silicon Bronze is a copper based filler metal containing 3% silicon and small amounts ofmanganese, tin and zinc. Primarily used for MIG, TIG and oxyacetylene welding of copper, copper-silicon andcopper-zinc base metals to themselves and to steel. Excellent for plain or galvanized steel sheet metal as well asother coated steels. The oxyacetylene gas flame should be slightly oxidizing. Keep the weld puddle small in order to promote fast solidification and minimize cracking. A high boric acid flux should be used both before and during welding. Preheating is NOT recommended.
♦ APPLICATIONS
- MIG, TIG and oxyacetylene welding of copper, copper-silicon and copper-zinc base metals to themselves and to steel.
- Surfacing areas subject to corrosion.

Copper and its alloys require a relatively high heat input with shortened welding time. Higher preheat temperatures and faster welding rates than for steel are necessary.
