Aluminum remains one of the most practical CNC materials because it machines quickly, supports tight tolerances, and balances cost with strong overall performance. The combination of low weight, corrosion resistance, and post-processing flexibility makes it useful across aerospace, robotics, electronics, medical devices, and industrial equipment.
Reference pages from Hubs and Xometry both emphasize aluminum's strong strength-to-weight ratio, machinability, and broad alloy selection. We see the same pattern in production: 6061 is a reliable general-purpose choice, 7075 is favored for higher strength, and other grades are selected when marine resistance, decorative anodizing, or higher fatigue performance matter.

General-purpose aluminum for machined housings, plates, mounts, and welded assemblies.
Higher-strength aluminum for weight-sensitive parts that still need strong mechanical performance.
Useful where corrosion resistance and formability matter more than peak strength.
Often chosen for aerospace-style applications where fatigue behavior and high strength are important.

For many projects, 6061 is the safest starting point because it is easy to machine, weldable, widely available, and balanced in cost and performance. If the part needs higher strength, 7075 is often the better choice. If corrosion resistance or marine exposure matters more, grades like 5052 or 5083 may fit better.
6061 is usually better for general-purpose machined parts, fixtures, housings, and welded assemblies. 7075 is stronger and more suitable for high-load parts, but it is usually selected when the strength advantage justifies the material premium and different downstream requirements.
Anodizing is one of the most common choices because it improves corrosion resistance and surface durability while supporting cosmetic color control. ZigiTech can also review bead blasting, brushing, chromate conversion, and powder coating based on the part function.
