This brazing alloy is predominantly made of Copper (Cu) and Phosphorus (P), formulated specifically for excellent joint strength and low melting temperatures.
When brazing copper-to-copper joints, no additional brazing flux is required because the phosphorus content in the alloy acts as an integrated self-fluxing agent. However, flux is recommended when joining brass or bronze.
It is heavily utilized in HVAC systems, refrigeration, plumbing, heat exchangers, and electrical motors. It is ideal for connection points requiring high corrosion resistance and high-fatigue performance.
Yes. While we provide standard round, square, and flat configurations (such as BCuP-2 sizes), custom sizes can be manufactured based on customer requirements.
We use standard export seaworthy packaging that includes protective polyethylene film and driers inside moisture-resistant cartons. Popular units are 5.67kg/bag (11.34kg/carton) or 5kg/bag (10kg/carton).
