HOW MUCH COPPER IS IN THE ALUMINUM????????????
Good grief Charlie Brown!!!
Does Scientific Method ring a bell with anyone?

Wish we knew more about the aluminum alloy.  Previous posts say that Rockwell Grade 5 is a hardness number, however I see only hardness LETTERs on the chart. Hoping that something will indicate the alloy mixture.

Someone posted a few msgs. back,that they recognized this
material,,,that they worked with it?


Can you pove a little more info?
