Fluxes are chemical compounds applied to the joint surfaces before brazing.
Their use is essential in the soldering/brazing processes.
Heating a metal surface accelerates the formation of oxides, the result of chemical combination between the hot metal and oxygen in the air.
This oxide layer has to be removed before brazing, and the formation of a new oxide layer has to be prevented, or they will inhibit the filler metal from wetting and bonding to the surfaces.
Anhui Huazhong Welding Material Manufacturing Co., Ltd is established in 2004, and located in Hefei——the central City of Anhui Province.
We are specialized in manufacturing and producing brazing materials.
Our main products include silver-based brazing filler metal, copper-based brazing filler metal, aluminum-based brazing filler metal and associated brazing flux, flux-cored welding wire etc.
Our brazing flux products include: silver welding paste, silver welding powder, copper welding paste, copper welding powder, aluminum welding paste, aluminum welding powder, spot welding paste (water), etc. The available shape of brazing alloys are rod, ring, sheet, strip, wire etc.
