Phos-copper (BCuP-2) low cost alloy is suitable for most copper to copper or brass joints where good fit-up exists and the assemblies are not subject to vibration or movement. Developed primarily for use on copper, this alloy may also be used on other non-ferrous copper base alloys. This product is used extensively on refrigeration units, air conditioning apparatus, electrical conductors, copper and brass pipe fittings, as well as other copper and brass equipment. By virtue of its phosphorus content, this product is self-fluxing on copper only applications. A flux should be used when brazing brass or bronze with this product.
