Phos-copper Brazing Alloys

CLASSIC Phos-copper brazing alloy is the low cost alternative for brazing copper and copper alloy base metals and is engineered to provide excellent fluidity, great strength and smooth processing property.

There is absolutely no need to add flux while brazing copper and silver.The product should not be used on ferrous and nickel based alloys, in order to avoid premature failure of the joint due to the formation of brittle intermetallic phases.

Phos-copper brazing alloy is mainly used for brazing copper parts in refrigerators, air-conditioners, evaporator, heat exchanger, water heater, and other non-ferrous industries.
