Product Description

4047 Aluminum welding flux paste

1. The Introduction of Aluminum flux paste
Aluminum flux paste is a gray paste-like brazing material made of aluminum silicon metal powder, non-corrosive flux, and organic binder through a special process. The Aluminum flux paste is applied to the surface of the welding seam of the aluminum alloy to be welded, which is suitable for furnace brazing, flame brazing, and induction brazing.

4. The Advantages of Aluminum flux paste:
The Aluminum flux paste is in the form of a paste, which can be applied to any shape of solder joints; after coating, it is brazed in the furnace, and the soldering residue is small;
The main advantage is that it is especially suitable for aluminum brazing of workpieces with complex powder surfaces, irregular shapes and large brazing areas.

5. The Application of Aluminum flux paste
Aluminum flux paste is mainly used for brazing in a furnace with a protective atmosphere between pure aluminum and pure aluminum or aluminum and stainless steel.
