2124Welding Property
Alloy Resistance welding Melting welding Argon arc welding Note
2124 Good Worse Worse For gas welding and argon arc welding of aluminum alloy as solder, tend to form crystalline cracks; 4A01 alloy solder, forming cracks tend to be significantly reduced, but the strength of welded joint is greatly reduced, such as heat treatment after welding, the joint strength is close to the substrate, but the ductility decreases.

Alloy Temper Aircraft type Application parts and typical parts
2124 Aluminum plate: O、T351、T361、T851、T861
 
F-15,F-16, Y8, J10etc. Strengthen the frame, joint, beam and so on.
