Steve,
     The company that I have the information is Ryerson Tull, INC
Their subsidary is Joseph T. Ryerson & Sons, INC.  They have many
distribution points across the U.S. and here is the data since I finally
remembered to bring my data book to work with me.

Yield Strength: 40,000 psi
Brinell Hardness: 95
Ultimate Shear Strength: 30,000 psi
Endurance limit: 14,000 psi
Modulus of Elasticity: 10,000 psi (Avg of tension and compression)


And for those that asked about 7075 T-6

7075 T-6, T651
Ultimate Strength: 83,000 psi
Yield Strength: 73,000 psi
Brinell Hardness: 150
