SUPERFLOW 0 BCuP-2 Phos-Copper Brazing Alloy – 1/8" x .050" x 20" – 1 lb Pack

Silver-free phosphorus-copper brazing alloy for joining copper, brass, and bronze.
SUPERFLOW 0 is an AWS BCuP-2 phosphorus-copper brazing alloy designed for close or controlled joint fit-up. The alloy contains approximately 7.0–7.5% phosphorus with the balance copper and produces a bright copper-colored braze.

SUPERFLOW 0 is self-fluxing when brazing copper-to-copper. When brazing compatible brass or bronze, an appropriate brazing flux is required.

Size: 1/8" x .050" x 20"
Package: 1 lb Pack

Important: Phos-copper brazing alloys should not be used on steel, ferrous metals, copper alloys containing more than 10% nickel, or in sulfurous atmospheres.
