Characteristics / Applications:

Copper-phosphorus alloy with low silver content. This alloy has good gap filling properties and is well suited to bridge wide gaps. Suitable for gap brazing of copper and copper alloys. Approved by DVGW-worksheet GW 2 for copper pipes. Joint-brazing at working temperatures between -20°C and +150°C. Do not use in sulphurous environment and on Fe- an Ni-alloys.

The main products of our company include welding ring, welding rod, welding wire and brazing flux of hundreds specifications. BCu91PAg copper-based welding wire is applied to the brazing of copper and copper alloy work pieces.

The welding wire has performances such as low melting point, excellent fluidity. The brazing joint has good mechanical strength and smooth surface. Applied the brazing flux of FB101 or FB102 can have a high quality brazing joint when it is used in brazing copper alloy.

The materials of BCu91PAg copper-based welding wire there are copper, phosphorus and silver. And the content of copper is 91%, phosphorus content is 6.8~7.2%, Silver content is 1.8~2.2%. BCu91PAg welding wire has many different specifications in order to Applicable to various needs of customers.
