710-810℃, low melting point, good fluidity, low cost, strong caulking. BCuP-2 phosphor copper welding rod composition: Phosphor (: 7%, Copper (Cu): the remainder. Phosphorus copper electrode welding copper pipe without flux, phosphorus is a reducing agent, can reduce cuprous oxide, phosphorus oxide floating on the sur-face of the weld, phosphorus copper electrode fluidity is good, with self-brazing. Flux must be added when copper and iron pipes are welded. BCU93P copper brazing rods for copper hvac is used for brazing of copper & copper alloy in motors, air-conditioners, meters, and refrigeration industry, copper solder for jewelry copper phosphorus brazing rod. Also can braze some pipes, wire or the small copper braze job and the art project., Weight: 0.30203329894 Pounds, Manufacturer: Jaywool
