6082-T6 parts machined on 16 simultaneous 5-axis centers, held to ±0.005 mm and inspected before every shipment. Send a drawing and get DFM feedback plus a quotation within 12 hours.
If any of these sound familiar, the fix is usually process control, not a new supplier.
A 3 mm wall on a 200 mm housing looks fine in the vise. Unclamp it and the flange lifts 0.15 mm. The part is scrap and the assembly shims no longer close. Soft jaws and a sequenced cut plan remove most of this risk before the first chip is cut.
A polished finish adds cost and cycle time. Buffing can also round a sealing edge and change the fit. We flag over-specified finishes during DFM review so you pay for the surface the joint actually needs.
On a 6082 plate with 60 M4 holes, a single setup error shifts the pattern 0.08 mm. The mating board will not drop in. Probing every hole on the machine catches the drift while the part is still clamped.
Hardcoat builds 25–50 μm per surface. A Ø10 H7 bore becomes Ø9.95 and the pin no longer slides. We machine to pre-plate dimensions and note the coating allowance on the drawing before anodizing runs.
6082-T6 cuts clean and holds tolerance. The work is deciding where to hold it and how much to take.
6082-T6 is a medium-strength alloy with good machinability. It cuts freely at 600–1,200 m/min surface speed, so cycle time is rarely the problem. Distortion is. A long extrusion or a thin plate moves when the clamps release, and the last 0.05 mm comes off a part that is no longer straight.
We plan the operation sequence around that. Roughing leaves 0.3–0.5 mm on critical faces, then a stress-relief pause, then finishing on soft jaws or a vacuum plate. For parts over 500 mm we use the Ø400 mm rotary table and finish in one continuous pass instead of repositioning.
On a rigid part with stable geometry, ±0.005 mm is repeatable across a production run. On a 4,000 mm extrusion with a 2 mm wall, it is not. Thermal growth alone moves a part that long by more than the tolerance over a 5 °C shop swing. We tell you which category your part falls into before quoting.
As-machined 6082 lands around Ra 1.6–3.2 μm. Where a seal or a sliding fit needs better, we take it to Ra 0.8–1.6 μm with a finishing pass and a change of insert geometry. Below Ra 0.2–0.8 μm means a separate operation, and we will say so.
Pick by strength, corrosion demand and how the part will be finished.
| Alloy | Typical use | Watch out for |
|---|---|---|
| 6082-T6 | Structural frames, brackets, housings | Lower fatigue strength than 7075 |
| 6061-T6 | General parts, enclosures, fixtures | Softer, threads wear faster |
| 7075-T6 | High-load aerospace and tooling | Poor weldability, costlier stock |
| 2024-T4 | Fatigue-loaded aircraft parts | Needs corrosion protection |
| 5083 | Marine plates, weldments | Harder to get a fine finish |
| ADC12 | Die-cast housings, high volume | Porosity in thick sections |
Most 6082 parts need one machining operation and one finishing step. Some need more.
16 simultaneous 5-axis centers for contoured faces, angled holes and parts that would otherwise need four setups.
27 three-axis and 12 four-axis machines for prismatic parts, plates and brackets where extra axes add nothing.
16 mill-turn centers handle shafts, bushings and fittings with cross-holes or flats in a single cycle.
One-off 6082 prototypes to check fit before tooling or a production run is committed.
Anodizing, hardcoat, plating, powder coating, bead blasting and laser marking, coordinated as one step.
For enclosures, the frame can be machined while the cover is formed or cast, then assembled and checked together.
Fifteen years in Dongguan, three plants, and a process that is measured rather than described.
Three wholly-owned plants across 7,600 m², with 150 technicians on the floor.

6082-T6 runs about 20 percent stronger than 6061-T6 in yield and holds up better in structural frames and brackets. It also machines slightly cleaner.
Choose 6061 when you need deep anodized colour consistency or the part is mostly cosmetic. Choose 7075 when the load is high and cost is secondary. 6082 sits in the middle and covers most industrial parts.
A 0.5 mm end mill is practical for slots and pockets, but depth is limited to roughly two times the diameter. Deeper pockets need a larger tool or a different geometry.
Threads down to M1.6 are cut with a tap or milled. Below that, thread strength in aluminium gets marginal and we will suggest an insert instead.
Clear and colour anodizing build 5–15 μm per surface and change the dimension by that amount. Hardcoat builds 25–50 μm and is much harder to control on edges.
Tell us the coating on the drawing and we machine to the pre-plate size. If a bore is a press fit, the allowance matters more than the finish callout.
Yes. There is no minimum order quantity, from a single prototype to runs over 10,000 parts.
Prototypes are usually cut from the same 6082-T6 stock as production, so the material behaviour matches. Process adjustments made on the prototype carry into the production plan.
A 2D drawing with tolerances and a 3D model if you have one. Note the critical dimensions, the finish and any coating.
If a feature is unclear, an engineer asks before quoting rather than assuming. That is why the quote takes up to 12 hours instead of 2.
Parts over 500 mm go on the larger travels, up to 4,000 × 400 × 150 mm. Thin walls are roughed with light passes and finished after a pause so internal stress releases.
Below 1 mm wall thickness on a long part, expect to trade some tolerance. We will tell you the realistic range before you place the order.
As-machined is Ra 1.6–3.2 μm. A finishing pass reaches Ra 0.8–1.6 μm, and Ra 0.2–0.8 μm is available where specified.
Beyond machining: clear, colour, hardcoat and conductive anodizing, electroless nickel, zinc, silver and gold plating, powder coating, black oxide, bead blasting, tumbling, brushing and polishing. Laser marking goes down to 1.5 mm character height.
Uploads are secure and confidential. An NDA is available on request before any drawing is shared.
ISO 27001:2022 is held for information security, so document handling follows a defined process rather than an informal one.
A process engineer reviews the file, flags anything that will not hold tolerance, and returns a quotation within 12 hours.
