Role of Phosphorus in Copper-Phos Brazing Alloys

Copper-phos brazing alloys are widely used for brazing copper-copper joints due to their excellent performance and inexpensive cost.

Copper (Cu) and phosphorus (P) are the main elements of the solder. Firstly, phosphorous can significantly decrease melting temperature of copper. And it gives the brazing alloy a self-fluxing property.

Hua Guang Welding Brazing Copper with Copper Phosphorus Alloy

Copper-phos brazing alloys may have different compositions and varied solid-liquid temperature intervals. The brazing alloys with wide melting temperature range are suitable to braze joints with wide or uneven
