 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.
Qixing Welding started in the 1980’s, we are the member of China Welding Association and Henan Welding Professional Committee Syndic Unit. Our company approved by ISO9001:2008 and ISO4001:2004, and all of the products meet SGS and ROHS directive requirements.
