SPECIAL AL ALLOY WELDING WIRE

Special Al Alloy Welding Wire Product Features
Excellent high temperature performance: The welding wire has excellent high temperature strength and creep resistance by adding some refractory metal elements, and can maintain a stable welding effect under high temperature environment.
Good welding performance: The melting process is stable and there is no spatter. The welding wire has good flow and spreading between layers, and it is not easy to have defects such as side wall unfusion, which can form a beautiful and defect-free weld.
Excellent crack resistance and mechanical properties: Taking 2195 aluminum-lithium alloy welding wire as an example, its fusion welding joint is mainly composed of α-Al, Al₂Cu, Al₃(Ti,Zr) phases, with excellent crack resistance and mechanical properties, extremely low crack sensitivity, and the tensile strength of the joint at room temperature is about 390MPa, and the elongation is 6.3%.
