Copper-Aluminum flux cored welding wire, a kind of brazing material, which can weld copper and aluminum materials by brazing, that's why we name it as copper aluminum welding wire, this is a kind of new materials, has been widely used in industrial.
Due to the copper price is three times higher than the aluminum price, so currently many manufacturers are update their technology, for example for one product, they will use the aluminum instead of copper if they can be replaced, If not, they will still use the copper.
How to braze these two different metal material, copper aluminum welding wire is the way to solve the problem.
Copper-Aluminum flux cored welding wire is a kind of composite brazing materials with Zinc-Aluminum alloy and white fluoride flux inner, the white brazing flux is non hygroscopic, non corrosive, no need to clean after welding. At present, it is mainly used in copper and aluminum alloy, brass and aluminum alloy, aluminum alloy and aluminum alloy flame brazing, high frequency induction brazing, furnace brazing.
To weld copper and aluminum together ，the procedure is used brazing metal filler as media by brazing process (actually is the metallurgical reaction, the brazing materials enter into the copper and aluminum molecular structure through capillary action), and the joint performance is good, and also with good Tensile shear resistance, good electrical conductivity and corrosion resistance. It is one of the commonly used methods of copper aluminum soldering.
Copper: red copper, brass
Aluminum and aluminum alloy: 1xxx; 2xxx; 3xxx; 4xxx, 4xxx; 6xxx etc.( AA standard)
Gas: LPG + Oxygen; or acetylene + oxygen; or propane+ oxygen
