BCuP-5 is a phos-copper-silver alloy ideal for
most copper-to-copper or brass joints where
close fit-up does not exist and where agitation
and vibration in service are involved. Containing
approximately 15% silver, this product has
long been the standard in the refrigeration industry.
Developed primarily for use on copper,
this alloy may also be used on other nonferrous
copper base alloys. This product is used
extensively on refrigeration units, air conditioning
apparatus, electrical conductors, copper
and brass pipe fittings, and 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.
Applications
• Applications with joint clearance of
.002" - .006"
• Refrigeration units
• Electrical conductors
• Copper and brass fittings
• Air conditioning apparatus
• Copper and brass equipment
