Having dealt extensively with metallurgy in my background I can tell you that your statement there is way off.
Welcome to the forum and all but please don't post a silly comment like that again.
Just in aluminum alone tensile strength and hardness vary a great deal. The strongest aluminum alloy is over 100 times stronger than the weakest aluminum alloy. There are so many varying grades and types of every allow nothing even begins to be equal to that of another for any given application. ASME has numerous books with the wide ranging standards of all metals and alloys from plane carbon steel to zirconium and tantalum.
Then you have the way the metals are processed which varies quite a bit even for the same alloy. Metals can be cold rolled, hot rolled, cast, etc. Then there is annealing processes, hardening processes, along with anodizing which does a great deal to improve wear quality of metal on metal contacts. Anodizing alone has various levels which affect the quality and strength based on the type and process of the anodizing. Hardening works the same way and varies a great deal based on the process and desired result.
Also please go back to what _paralyzed_ said and understand neil is only offering help and advice. He can be a bit abrasive but that is just his British personality coming through.
