15% silver solder
Alias: Material 204(L204)
Conforms to GB BCu80PAg
Equivalent to AWS BCuP-5
Description :
BCuP-5 is a copper scale filler metal containing 15% silver. The joint strength, plasticity, electrical conductivity and the ability to fill uneven gap are the best among copper-phosphorus brazing materials, and the requirements for joint preparation and assembly gap are relatively low.
Application:
Suitable for brazing copper and copper alloy, silver, molybdenum, tungsten and other metals. Most of them are used for brazing workpieces with small shock shock load, which are used most in the motor and electrical industry.

Note:
1. Before brazing, grease, oxide and other dirt must be strictly removed from the brazing site and the surface of the brazing filler metal.
2. No brazing flux is required when brazing copper, but silver flux should be used when brazing copper alloy.
We will use professional export fumigation-free wood, according to the actual number of products customized wooden boxes, wooden trays, etc. It should be noted that different products have different packaging, the specific model and specifications to determine, of course, we are very willing to package according to customer requirements. The transportation mode is mainly sea and land transportation, and the specific need to negotiate with the customer to determine.
