OVERVIEW

Precision Aluminium Machining with Cosmetic Anodising

Aluminium cuts fast and looks excellent when the machining and finishing are done correctly. Our high-speed milling and turning control burrs, tool marks and chatter, then we finish the parts to a uniform anodised, sandblasted or brushed surface — so your visible housings and structural parts arrive ready for assembly.

MATERIALS

Aluminium Grades We Machine

We stock certified aluminium bar, plate and block and advise on the right grade for strength, corrosion, machining and anodising.

6061 T6 / T651

The general-purpose workhorse: good strength, machinability, weldability and anodising for housings, plates, brackets and structural parts.

6063 T5 / T6

Excellent surface finish and anodising response, commonly used for frames, profiles, trims and visible cosmetic components.

7075 T6 / T651

High-strength aerospace alloy for robot, motorsport and high-load parts where stiffness-to-weight is critical; less corrosion resistant than 6061.

5052 H32

High corrosion resistance and formability for panels, enclosures and marine/chassis components with a smooth finished surface.

2024 T3 / T4

High-strength, fatigue-resistant aerospace alloy for structural and motorsport components, often used with protective coatings.

MIC-6 / ACP Cast Plate

Cast tool-and-jig plate with exceptional inherent flatness and stability for precision fixtures, baseplates and vacuum plates.

Aluminium Extrusions

We machine aluminium extrusions and profiles to final length and geometry, adding precision holes, pockets and end features.

Other / Customer Stock

5083, 6082, ADC12 die-cast and other aluminium grades, plus customer-supplied material, quoted on request.

SURFACE FINISH

Aluminium Surface Treatments

We specialise in the cosmetic and functional finishes that aluminium parts are known for, with careful masking of precision features.

Clear Anodising

Natural silver anodising that adds corrosion resistance and a clean, uniform look without changing the colour of the part.

Black Anodising

Deep, consistent black anodising — one of the most popular cosmetic finishes for housings, electronics, robotics and optical parts.

Red / Blue / Colour Anodising

Coloured Type II anodising in red, blue, gold and other colours for branding, identification and two-tone cosmetic effects.

Hard Anodising (Type III)

Thick, hard, wear-resistant anodising for sliding surfaces, tooling, bores and heavy-duty components, with or without colour.

Sandblasting / Bead Blasting

Fine bead blasting before anodising removes tool marks and gives a uniform, satin, premium matte cosmetic surface.

Brushing / Chromate

Linear brushing for a classic metal look, or chromate/chem-film conversion for electrical conductivity and corrosion protection.

FAQ

Aluminium CNC Machining FAQ

Practical answers from our engineering team. Still unsure? Send your drawing and ask.

Which aluminium grade should I choose?
6061 is the default for a good balance of strength, machinability, weldability and anodising; 7075 for high-strength/aerospace parts, 6063 for best cosmetic anodising and extrusions, 5052 for corrosion-resistant panels, and MIC-6 cast plate for flat fixtures. We recommend a grade during the free DFM review.
What tolerance do you hold on aluminium CNC parts?
Our standard follows ISO 2768-mK and we routinely hold ±0.01 mm on critical bores, mating faces and hole positions. Aluminium machines predictably, so we also control thin-wall deflection and flatness on lightweight parts.
Can you anodise aluminium parts in different colours?
Yes. We offer clear/silver, black, red, blue, gold and other colours of Type II anodising, plus hard anodising and two-tone effects. Sandblasting or brushing before anodising gives a uniform, premium matte or satin appearance.
What is the difference between anodising and hard anodising?
Standard Type II anodising is a thinner, colour-friendly decorative and corrosion-resistant layer. Hard anodising (Type III) is a much thicker, harder layer used for wear and abrasion resistance on sliding surfaces, tooling and bores, and it can be masked or coloured.
Can you machine heatsinks and thin-walled aluminium parts?
Yes. We machine high-fin-density heatsinks and cold plates as well as thin-walled housings and pockets, using high-speed strategies and careful work-holding to avoid chatter and distortion while keeping the parts flat and burr-free.
Do you provide material certificates and CMM reports?
Yes. Mill test certificates (EN 10204 3.1), first-article inspection reports and CMM dimensional reports with measured values are available on request, so every aluminium batch is traceable and documented.
What is the minimum order quantity for aluminium parts?
There is no fixed MOQ. We make one-off aluminium prototypes and pilot batches through to high-volume serial production; aluminium is fast and economical to machine, so prototype lead times are short.
How do you ship aluminium parts to the USA and Europe?
We protect anodised surfaces with film and protective packaging and ship by DHL/FedEx/UPS, air or sea freight under EXW, FOB or DDP terms. DDP to Germany, France, Italy, Spain and other EU countries includes customs and duty for door-to-door delivery.
