This is not a true statement. The different alloys properties do vary greatly, but their modulus does not. checking aluminum
alloys 3003, 5086, 6061, and 7075, in tempers ranging from H-0 to T6, I find all listed modulus's are from 10,000,000 to 10,600,000. This difference is insignificant.
It is common knowledge that all steel
alloys have the same modulus.
When working with properties of strength, corrosion
, etc alloy and heat treat are very significant. When working with modulus of elasticity they are not, at least as regards aluminum and steel alloys.
