Aluminum CNC Machining

Precision CNC machining for aluminum alloys 6061, 7075, 5052, 6063, and 2024. 3-axis to 5-axis milling and turning. Anodizing and surface finishing available.

Why Aluminum

Lightweight, Strong,
Cost-Effective

Aluminum is the most widely machined metal — and for good reason. It's lightweight, strong, corrosion-resistant, and machines 3–5x faster than steel. For prototypes and production parts alike, aluminum delivers the best balance of performance, cost, and lead time.

At YEYUAN CNC, we machine aluminum daily. Our tooling, speeds, feeds, and coolant strategies are tuned for each alloy grade — from easy-cutting 6061 to the higher demands of 7075 aerospace aluminum.

Alloy Grades

Aluminum Alloys
We Machine

Aluminum 6061

Most versatile aluminum alloy. Good strength, excellent corrosion resistance, and great machinability. The go-to choice for general-purpose machining.

Typical Applications: Prototypes, structural brackets, electronic enclosures, bicycle frames, marine hardware.

Aluminum 7075

High-strength aerospace-grade aluminum. Comparable to mild steel in strength at 1/3 the weight. More challenging to machine than 6061 but delivers exceptional strength-to-weight.

Typical Applications: Aerospace structural components, high-stress bicycle parts, rock climbing equipment, molds and tooling.

Aluminum 5052

Excellent corrosion resistance, especially in marine environments. Good formability and weldability. Lower strength than 6061/7075.

Typical Applications: Marine hardware, fuel tanks, sheet metal enclosures, chemical processing equipment.

Aluminum 6063

Architectural aluminum with excellent surface finish after anodizing. Medium strength, very good extrudability.

Typical Applications: Architectural extrusions, window frames, heat sinks, furniture, decorative parts.

Aluminum 2024

High-strength aerospace alloy with excellent fatigue resistance. Lower corrosion resistance — typically used with alclad coating.

Typical Applications: Aircraft structures, military vehicles, truck wheels, precision fittings.

FAQ

Common Questions

6061 vs 7075 — which should I choose?

6061 is the default — good strength, great corrosion resistance, easy to machine, lower cost. Choose 7075 only if you need steel-like strength at 1/3 the weight. 7075 costs about 30–50% more and can't be welded. When in doubt, send us your application details and we'll recommend.

What anodizing options are available?

Type II (decorative) anodizing in clear, black, blue, red, gold, and green. Type III (hardcoat) for wear resistance — typically dark gray or black, 50–75μm thickness. We also offer chemical film (chromate conversion) as a lighter, cheaper alternative for corrosion protection.

What's the lead time for aluminum parts?

Typically 3–7 days for prototypes (1–10 pcs), 7–15 days for production runs. Rush service available — we've turned simple parts in 48 hours. Anodizing adds about 2–3 days because it's done off-site at a partner facility we've worked with for years.

Can you match an existing part I have?

Yes. Send us the sample and we'll reverse-engineer it — 3D scan or manual measurement depending on complexity. We'll create a STEP model and send it for your approval before cutting metal. This works well for legacy parts where the original drawings are long gone.

What if my design isn't optimized for machining?

That's exactly what our DFM review is for. We'll flag: walls that are too thin, pockets that are too deep, internal corners without radii, unnecessary tight tolerances, and features that require expensive setups. You get a marked-up drawing with suggestions — implement what makes sense, ignore the rest.

Do you keep spare parts or hold inventory?

We can hold safety stock for regular production parts — you give us a forecast, we build ahead, and ship on your schedule. Minimum for stock-holding agreements is usually 3 months of consistent orders. Storage is free for the first month.
