 Introduction

Copper Phosphor Brazing Filler Metal(0 silver solder) is base on the raw material with the binary alloy of copper-phosphorus. It has good fluidity, low cost, perfect processing property. No need to add flux when brazing copper and copper, and the joint has good strength and close tolerance can be maintained. It is suitable for the field of HVAC system, such as air-conditioners,refrigerators. and evaporator, heat exchanger, water heater, etc. 
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. We take more than 60-70% marketing shares in domestic, including the international famous companies, such as Midea Group and Gree Electric Appliances, Danfoss, Panasonic, LG, Samsung, etc.
