BCuP-5 Silver PhosCopper Brazing Rod - 15% Silver - Flat - 1/8" x 0.05" x 20" + 6.5 Oz Flux

Silver Phos-Copper 15% was developed primarily for use on copper, but its use has extended to other nonferrous copper base alloys. It is used extensively on refrigeration units, air conditioning apparatus, electrical conductors, copper and brass pipe fittings, and other copper and brass equipment. Silver Phos-Copper 15% is a copper rich, filler metal that is self-fluxing on copper by virtue of its phosphorus content. The self-fluxing property of this filler metals is effective on copper only. With copper-base alloys, such as brass or bronze, the joints should be fluxed. Silver Phos-Copper 15% should not be used on nickel-base and iron-base alloys, as the phosphorus reacts with the nickel or iron to form brittle compoundstage the interface of the joints. Silver Phos-Copper 15% should not be used where the joints are exposed to sulfur compounds, especially in gasses or oilstage temperatures above normal room temperature. As the corrosion by sulfur is cumulative, even very Small percenta
