Horizon Aluminum Based Brazing Alloys are used for welding those aluminum alloys which dont have high requirement for joints. The seam of Aluminum Base Brazing Alloys with good crack resistance and versatility. Suitable for aluminum gas welding and argon arc (No for high magnesium alloy)ã?? Horizon Al-Al Flux Cored Brazing Alloys, high strength, good flow, non-corrosive flux. Suitable for welding aluminum to aluminum, aluminum alloys. No flux when brazing, welding as normal flame welding.
