Properties of Aluminium 7075

Please can anyone help me with the properties of Aluminium 7075 so that it can be used to model the material for a CubeSat frame in CST

Thanks in advance :)

https://en.wikipedia.org/wiki/7075_aluminium_alloy

Actually, I needed some properties like permittivity for simulating in CST

Not sure if this helps but I see the dielectric constant of aluminum powder listed as 1.6 - 1.8. If I'm not mistaken it varied greatly between aluminum powder and aluminum shavings. I did not see any information regarding 7075 specifically.

permittivity of a metal? It's presumed to be imaginary.
