FAQ Electron Beam Welding of Copper to Aluminum

 "IS IT POSSIBLE TO WELD COPPER (Cu) TO ALUMINUM (Al) BY ELECTRON BEAM?"
Yes. It is feasibly possible to join these two materials together through the electron beam welding process. Some alloy combinations may work better than others HOWEVER the resulting weld is brittle with very little structural integrity. Although you may experience some success in developmental sample welds, reliable reproduction of those results can become an issue so (if at all possible) this material combination is not recommended to be used in any critical applications.
