BCuP-3 (5% Silver)
Alloy Type: A5.8, BRAZING Filler Metals
BCuP-3 is a phos-copper-silver alloy suitable for most copper-to-copper or brass joints where close fit-up cannot necessarily be maintained, and the assemblies are not subject to vibration or movement. This product is somewhat more ductile than BCuP-2. Developed primarily for use on copper, this alloy may also be used on other nonferrous copper base alloys.
Typical Applications: applications with joint clearance of .003”-.006”; refrigeration units; electrical conductors; copper and brass fittings; air conditioning apparatus, copper and brass equipment
