Aluminum 7075
The strength option — roughly twice the yield of 6061, at a real cost in corrosion resistance and machining.
Tougher to cut than 6061 and it will not let you leave a sharp edge. Some shops try 6061 first because it is easier; we quote 7075 when the drawing calls for it.

Figures below are what our shops achieve on prototype quantities. A production order may justify tighter — or looser — tolerances, and that is a conversation, not a default.

What engineers ask about Aluminum 7075
These are the questions that come up on almost every Aluminum 7075 drawing. If your question is not here, send it with the drawing and we will answer it in the quote.
Is 7075 worth the extra cost over 6061?
Only if the part is actually load-limited. We review the drawing and tell you which features carry the load and which do not — a hybrid approach often removes the premium without losing performance.
Why does 7075 corrode faster than 6061?
Its higher alloy content gives it less resistance to galvanic and salt corrosion. For exposed parts we discuss a protective coating or a substitution before quoting.

When not to use Aluminum 7075
We would rather tell you on day one than ship you a part that was never the right answer. If one of these applies to your project, say so in the enquiry.
- Marine or salt-spray service without a protective coating
- Parts where machinability and cost are the deciding factors — 6061 is usually the better answer
- Cosmetic anodised parts where 6061 would look identical
