 Introduction

Aluminum base brazing alloys is mainly used for brazing aluminum with aluminum alloy. The brazing aluminum with aluminum alloy use Al-SI Flux-cored wire to substitute ordinary ER4047 wire, with corrosive flux inside, easy to welding. It is particularly suitable for brazing aluminum parts in refrigeration, air-condition and automotive industry.
Copper-Aluminum flux-cored wire is an innovation environmental brazing material especially designed for electrical component. It can easily achieve the brazing of copper row with aluminum row, copper wire with aluminum wire. Brazing alloy composition meets ROHS directive. The powder in the wire center is the flux impacting on brazing alloy’s fluidity in Copper-Aluminum base metal, is a combination from different kinds of fluoride, non corrosive and very stable in normal atmosphere, so it can be kept in stock for long time without problem. For components with special brazing joints(big surface or different shape), we can provide alloy in wire or sheet form, matched with suitable flux in paste, which will be an easy solution for operators. It’s suitable for brazing copper with aluminum, aluminum with aluminum, aluminum with steel, aluminum with stainless steels, 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.
