Re: Which kind of Aluminum is a good choice

We use 2024-T3 (0.05") and 6061-T6 (0.09" and I think 0.063") for sheet metal. I believe we also have some 5052-H32 sheet laying around as well.

For general purpose stuff like superstructures and the like, 6061-T6 is generally the go-to.

For hex shafting, we either use 7075-T73 or 2024-T351 (we'll either get it from onlinemetals or mcmaster). As mentioned before, we've never had any sheared shafts when using aluminum.

Also, we come very close to being overweight every year (partly because of mismanagement of resources, but we also generally build tanks for robots for some reason).
