Products Detail
  • Product name: Copper-phosphorus-silver Brazing Filler Metals

Applications and Features

The product is used for brazing of copper and copper alloys. It has low melting point, excellent fluidity, and good brazing properties. The brazing joint has high mechanical strength and smooth surface. Flux is unnecessary when brazing copper. However, an appropriate flux is recommended when brazing copper alloys in order to get a high quality brazing joint.
The product is applied widely in the industries of refrigeration, machinery, electromechanical, electric appliance and instrument etc.
