Why Aluminum Is Our Most-Machined Material

We cut more aluminum than everything else combined. There's a reason for that — it machines beautifully, it's strong for its weight, and it doesn't break the bank. As a CNC aluminum parts custom processing manufacturer, AOOM Technology runs aluminum jobs daily across every industry you can name.

6061 vs 7075 — When to Use Each

6061 is the workhorse. It welds easily, anodizes well, and costs less. We use it for enclosures, brackets, housings, and prototypes. 7075 is stronger — closer to mild steel in tensile strength. We recommend it for structural parts, aerospace components, and high-load applications.

I had a client spec 7075 for a simple mounting plate that only carried 5 kg. Switched them to 6061, saved 30% on material, and the part still had a 5x safety factor. Knowing the grades saves money.

What We Can Do With Aluminum

Our 5-axis machines handle complex geometries in one setup. We mill pockets, drill angled holes, cut threads, and machine thin walls down to 0.5 mm. Surface treatments — clear anodize, hard anodize, powder coat, bead blast — we do them all in-house.

Tolerances: ±.005mm on critical features. Surface finish: Ra .8μm as standard, Ra .4μm achievable with slower finishing passes. We adjust our approach based on your requirements, not our convenience.

Prototyping to Production

A robotics startup came to us with a new gripper design in 6061. We machined 10 prototypes in 4 days. They tested, tweaked the design, and ordered 2,000 units. We ran the production batch with the same tooling and programs. Zero requalification needed.

Quality Checks on Every Part

CMM inspection isn't just for first articles. We check dimensions across the full run. Anodizing thickness is verified with eddy current gauges. Every shipment includes a certificate of conformance.
