6061 is the default workhorse

6061-T6 balances price, machinability, strength, and finish options for many CNC parts.

7075 is for strength

7075-T6 is useful for high-strength lightweight parts, but it costs more and may require careful corrosion protection.

5052 is a sheet metal favorite

5052 forms well and is common for bent enclosures, brackets, covers, and panels.
