Model: E8812NC
Characters
Aluminum brazing flux cored wire, the brazing wires is aluminum and silicon alloys .They have flux inside the wire. Unlike the regular brazing wire, flux-cored wires do not need extra flux and its relative operations. This kind brazing wire is favorable to flame brazing, high-frequency brazing and furnace brazing.
Advantages
1. Flux cored
No extra flux requied when operationg, it's much easy to brazing , also reduce waste.
2. Seamless surface
seamless surface can make the flux adequate distribution, avoid the flux leak out and damp the flux by water vapor
3. Non corrosive
no special treatment after brazing
4- Unique surface treating
oxidation is one of the difficult problem for aluminum brazing, we use a special surface treating process which can brighten the surface and reduce oxidation.
