Material replacement

Hi,
I am looking for a material for turning rather than casting with the same properties as A360.
I need to test a part that would usually be cast from A360 or A356, but the test-part can not be cast (as casting is way to expensive for a order size of 1).
The part is tube-shaped and will be tested by clamping one side and then trying to twist (with a giant pneumatic wrench) on the other end.

I need to know how and where I can find the right material for the test part. Is there a database where I can find materials by property?

A360 and 356 is aluminum... Contact you local materials distributor and buy some 6061 AL or equivalent.

Hi Kelly,
I was just looking into the specifications of 6000-series aluminium on matweb. Thanks for your help.
