Considering the thickness of your design, you are in a good position in terms of strength. For aluminum, I would lean towards 6061 or 7075. Both are excellent due to their mechanical properties and are a popular choice for durable parts.

Hello, I am designing a bottle opener and want to use aluminum. I need an alloy that is strong enough. The opener will not be very thin, I am thinking of 3-4 mm at the thinnest points, so it should not bend, but I still want to be sure here. Does anyone have a recommendation?

Understood, thank you. I know that 6061 is a bit easier to work with and performs well overall, but would 7075 provide a significant advantage in terms of strength for a bottle opener?

Absolutely, 7075 is significantly stronger and more resistant to stress than 6061, which might be overkill for a bottle opener, but would definitely ensure that it can withstand any lever force without bending. The choice between 6061 and 7075 could come down to how much you prioritize strength over cost.

That makes sense, I appreciate the insight. Considering the balance between cost and performance, I tend towards 6061. Thank you very much!
