Product Introduction

Phosphor-Copper brazing alloy is easy-flow, low-cost and has good processing property and self-braze ability. It applies to contact brazing、gas flame brazing, induction brazing and furnace brazing, the joint has high tensile strength and good electrical conductivity. Silver-Phosphor-Copper brazing alloy can reduce the melting points, in can improve both alloy's plasticity and wet ability, as well as the alloy's strength and toughness.

Technical guidance: copper phosphorus solder has the characteristics of good fluidity, low price and excellent process performance. Brazing red copper has self brazing property and no flux can be used. It is suitable for contact welding, gas flame welding, high frequency brazing and brazing in some furnaces. The brazed joint has good strength and conductivity. Copper phosphorus silver solder adds silver (Ag) to copper phosphorus alloy, which reduces the melting point of solder, improves the plasticity, strength, toughness and wettability to copper, and can replace some high silver solder.
