Aluminum cast 7075 equivalent

Aluminum cast 7075 equivalent

(OP)
I have a machined from block explosion proof box made out of 7075 aluminum, I would like to have it cast instead of machined, what kind of alloy will render similar properties to the machined out of stock 7075 aluminum?

RE: Aluminum cast 7075 equivalent

201 cast alloy would be the best you would be able to do. But,you will come up about 10ksi short on both yield and tensile compared to 7075-T73. If you are talking 7075-T6, you will be about 20ksi short with the 201 casting alloy. The elongation of the cast material will be about half that of the wrought 7075.
