Custom OEM Aluminum CNC Machining Parts

Aluminum CNC parts are used in almost every industry today. From high-performance automotive parts to lightweight components in aerospace and electronics, aluminum remains one of the most demanded materials for CNC precision. We have worked with this metal in real factory floor conditions, and it responds well under every machining operation.

If you are sourcing Aluminum CNC Parts from the USA, UK, Europe, or Asia, our facility can handle bulk orders and tight tolerance machining without delay. Whether it is for high-volume production or one off prototypes, we offer reliable CNC machining services using the right alloys and verified machining techniques.

  • OEM Custom Parts As per customer requirements and drawing or samples.

  • More then 50 Material Grade

  • Affordable Price For Bulk Quantity

  • Fast Shipping Wordwide

Products Made With Aluminum CNC Machining

We have machined aluminum into all types of parts. Not just prototypes or one-offs. Real production. Real loads. Real users.

    Heat Sinks and Cooling Plates

    Cut deep, balanced, and tapped. Often hard coat anodized. We have done these for LED panels, battery packs, and server racks.

    Mounting Brackets and Plates

    Common in aerospace interiors and camera rigs. Often thin. Needs good fixturing.

    Medical Casings and Frames

    Tapped holes, soft edges, no burrs allowed. Clean room prepped before packing.

    Bike and Auto Parts

    Handle mounts, pedal arms, throttle bodies. Finished smooth or coated matte.

    Drone Arms and Chassis

    Weight-critical. Often hollow or pocketed. Wall strength matters.

    Electronics Boxes and Covers

    Internal bosses, threading, gasket grooves. Often anodized after machining.

    Robotics End Effectors and Plates

    Sensor holders and motor plates. Often checked for flatness or parallelism.

    Custom Tools and Prototypes

    Test fixtures, jigs, clamps. Built for use, not display.

These are not items you find online. These are jobs built for actual machines and actual assembly lines. Every part goes through operator checks before boxing. It is not about volume. It is about doing it right.

What Types of CNC Processes We Use for Aluminum Parts

Different shapes and tolerances call for different machining setups. In our shop, the CNC operations depend on part geometry, material hardness, and finish requirements.

We use:

  • 3-Axis and 5-Axis Milling for accurate pocketing, slots, complex surfacing

  • CNC Turning for cylindrical and threaded parts

  • Drilling and Boring for holes within ±0.01 mm

  • Tapping for internal threads on lightweight parts

  • Wire EDM and Surface Grinding when extreme precision is needed

We also combine machining with deburring, polishing, and surface treatments to get the final component ready to use.

Finishing Options for CNC Machined Aluminum Parts

Finishing is where aluminum gets its final job done. You cannot skip it. A raw part may look fine today but will corrode or wear out in real use. We offer only finishes we have run ourselves. No catalog promises here. These have been tested on real jobs with real tolerances.

    Anodizing (Clear or Hard)

    Good for wear and corrosion. Makes parts stronger on the surface. We run type II and type III anodizing. Bath time and load spacing matter. Overcrowd the rack, and parts come out blotchy. We know. We have fixed it.

    Bead Blasting

    Takes off machine marks. Leaves a dull, even look. Used a lot for handles and casings. We control air pressure and media grade to avoid softening corners.

    Powder Coating

    Color with durability. Not just cosmetic. We pre-bake parts to avoid gas-out and then apply full coverage. We often coat parts that will live outdoors.

    Laser Marking

    For part numbers, logos, or trace codes. Works best after anodizing. Etch depth matters when parts face wear.

    Brushed or Polished Finish

    Some jobs want that clean visual touch. We finish by hand or wheel depending on request.

We match finishes to function. You do not anodize a sliding pin the same way you treat a bracket that just bolts down. Each one is handled based on how it will be used. That is not just a process that is attention.

Common Applications of Aluminum CNC Machined Parts

In the past two decades, we have supplied CNC aluminum parts across a wide range of industries. Each has its own drawing, alloy, and tolerance requirement.

    Automotive

    We have delivered brake levers, engine brackets, sensor housings, and valve covers in 6061 and 7075 aluminum.

    Aerospace

    Wing ribs, seat frames, and mounting blocks for aircraft cabin systems. Aerospace needs high strength with reduced weight.

    Electronics

    Heatsinks, laptop frames, connector housings. Aluminum is good for thermal and electrical use.

    Medical Devices

    Small batches of precision components for surgical equipment and diagnostic machines.

    Marine

    Rust-resistant fittings, clamps, and covers used in fresh and saltwater conditions.

Technical Capabilities for Aluminum CNC Parts

You need more than just a CNC machine. You need tolerance control, repeatability, and surface quality.

Our typical tolerances:

  • General parts: ±0.10 mm

  • Precision fit: ±0.05 mm

  • Hole diameters: H7 standard

  • Surface finish: Ra 1.6 to Ra 0.4 possible

Threaded options:

  • UNC/UNF, ISO metric, custom pitch

  • Internal/external threading with go/no-go inspection

Surface finish options:

  • Anodizing (clear, black, red)

  • Powder coating

  • Bead blasting

  • Chrome plating (on request)

Our team inspects every batch with micrometers, height gauges, pin gauges, and CMM when required.

Alloys of Aluminum We Work With

Each alloy offers different benefits. We help clients pick the right one based on strength, corrosion, machinability, and price.

  • 6061-T6 – The most balanced and widely used

  • 7075-T6 – Highest strength, used in aerospace

  • 2024 – Good fatigue resistance

  • 5052 – Excellent corrosion resistance, softer

  • 5083 – Marine-grade with high weldability

You can send your specs with alloy code or ask for a suggestion based on your application. We also offer raw material sourcing for full traceability.

Advantages of Aluminum Machining

Aluminum has more than one advantage. It is not just about weight. When handled right, it becomes the material that fits best in cost, function, and finish.

    Light Weight

    Easier to move. Less strain on equipment. Useful in anything that moves or lifts.

    Fast Machining

    Lower tool wear. Shorter cycles. Higher daily output.

    Heat Transfer

    Good for thermal paths. Used in electronics, power units, and battery builds.

    Surface Versatility

    Can be anodized, coated, etched, or left raw. Looks clean either way.

    Corrosion Resistance

    With the right finish, it lasts outdoors, near salt, or around chemicals.

    Cost-Effective

    Price per part drops fast after the first few runs. Tooling lasts longer. Less spindle time means lower hourly costs.

We have seen all this firsthand. A well-machined aluminum part just works. It does not crack under torque. It does not warp during mounting. It aligns, fits, and holds.

That is what matters.
