If there were any other people that knew anything about metallurgy on this forum they would be saying the same thing, but it seems that everyone on this forum is dumb, and stubborn, so Im not going to try to tell you the proper terminology anymore, as you are too dumb and stubbron to care. Keep on using your zinc/copper, or steel/magnesium/molybdenum/tugsten, or aluminum/copper/titanium/zinc "alloy" arms.
