Introduction of flux cored aluminum welding wireFlux core aluminum welding
 
Flux core aluminum welding, also known as aluminum-aluminum welding wire, is a type of welding wire that can be brazed directly by flame or induction.
Flux core aluminum welding produced by Henan Signi Aluminium: Aluminum-silicon flux-cored welding wire for aluminum-aluminum welding, instead of ordinary ER4047 electrode, no welding powder is needed. At present, the market usage is very large. It is one of our main products. It can be made into strips and rings for easy use according to customer needs. Its welding effect is almost the same as that of imported welding wires from Korea and France, but the price is half cheaper. Friends of brazed aluminum products welcome you to try this product.
