Brass is our core, but we also machine selected aluminium and copper parts on the same precision turning lines — made to your drawing.
Some applications call for the light weight of aluminium or the conductivity of pure copper. We turn finished components from a focused, proven range of both — not a full alloy catalogue, but the grades our customers actually specify, held to the same tolerances and finish standards as our brass work. We machine parts from bar; we don't sell bar stock.
Aluminium parts: turned from 6061 & 6063
Copper parts: turned from C11000 (ETP)
Process: CNC turning & milling
Finishing: anodising (Al), plating (Cu) on request
Aluminium is roughly one-third the weight of brass with excellent corrosion resistance and a clean anodised finish — ideal where mass, not conductivity, drives the design.
| 6061Al-Mg-Si, T6 | Strong, weldable — general structural & mechanical parts |
| 6063Al-Mg-Si | Superior surface finish & anodising — visible turned parts |
Density ~2.70 g/cm³ · machined from round & hex bar · anodise-ready.
Electrolytic-tough-pitch copper is ≥99.90% pure with ~100% IACS conductivity — the choice when a part must carry current or heat that brass cannot.
| C11000Cu-ETP / CW004A | Electrical terminals, busbars, grounding, EV contacts |
Density ~8.96 g/cm³ · high thermal & electrical conductivity.
Full C11000 datasheet| If your priority is… | Choose | Why |
|---|---|---|
| Light weight / pneumatics | Aluminium 6061/6063 | ~⅓ the density of brass; strong-to-weight; anodisable |
| Electrical / thermal conductivity | Copper C11000 | ~100% IACS — far above brass; ideal for terminals & EV |
| Machinability, threads & DZR | Brass (core range) | Best all-round machining, thread strength & water suitability |
Note: aluminium and copper need galvanic-compatibility care in mixed-metal assemblies. We'll advise on the right grade for your application.
Typical values for the grades we machine, with brass (CW617N) shown for reference. Confirm against the full datasheet for design-critical work.

All made to your drawing in the grade you specify — we machine components, not finished assemblies; assembly and any approval remain the buyer’s.
| Metal | Finish | Purpose |
|---|---|---|
| Aluminium | Clear / colour anodise (Type II) | Corrosion resistance, colour, durable surface |
| Aluminium | Hard anodise (Type III) | Wear resistance for moving or load-bearing surfaces |
| Aluminium | Chromate conversion | Conductive corrosion protection & paint base |
| Copper | Tin / nickel / silver plating | Solderability, low contact resistance, anti-tarnish |
| Copper | Passivation | Reduce oxidation on bright copper |
Finishing is performed by qualified partners with our QC oversight; specify coating thickness and any contact-resistance or salt-spray requirement at quotation.
Aluminium and copper parts run on the same CNC turning and milling equipment as our brass components, with the same in-process inspection. Tooling, speeds and feeds are tuned per material; finishing (anodising for aluminium, plating for copper) is arranged on request.
Send your drawing or sample. We'll confirm the right grade, machining route and finish, and quote within 24 hours.
Aluminium and copper grades are machined to the published standards below; mill certificates per EN 10204 Type 3.1 are supplied as standard. Open any link to verify with the publishing body.
Last reviewed: June 2026. All parts are made to order — confirm grade, finish and tolerance at quotation. Brassland machines components to your drawing and holds ISO 9001, 14001 & 45001 only; product approval, performance testing and assembly of the finished part are the buyer’s responsibility.
