Aluminum alloy welding wire:

1. The aluminum alloy welding wire, developed for brazing, lower melting point and higher fluidity than ER4043, also can be used as welding filler. It can be used in place of 4043, more silicon element, which will minimize hot crack and strength higher fillet welding shear.   

2. Chemical Composition (elements by weight %)

7. Application:

Welding or brazing light alloy industry

8. Product Advantages:

1). Independently research and develop the entire production process, deploy specific chemical composition according to customer demands

2). Adopting unique machine scraping and skinning technology, reducing air pollution, avoiding bubble formation when welding.

3).  Little Spatter , low noise, forming well, efficient energy saving and improving the  welding quality
4).  Bright and smooth Surface finish, stronger wire feeding.
5).  Superior arc stability, perfect welding performance, to ensure the product speed and efficience, used by a large number of overseas and domestic key projects.
