Phos-Copper-Silver Brazing Alloy

Introduction

Phos-Copper-Silver Brazing Alloy(Low Silver solder) can reduce melting point, improve plasticity of brazing alloy and wettability of copper, as well as brazing alloy’s strength and toughness. With good fluidity and brazing property, this kind of brazing alloys is suitable for brazing copper and copper alloy parts, and some can be suitable for brazing shake copper with copper, copper with brass in air conditioner and freezer; brazing copper with copper alloy joints in electric motor and meter.
