VT machining provides CNC Honing Tungsten Copper for customers who need accurate, repeatable Tungsten Copper components. Because Tungsten Copper is combines tungsten strength with copper conductivity, we adapt the process to suit — controlling the variables that matter for this alloy.

Published typical values for W75Cu25. Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.
Two phases with very different behaviour in one part. EDM gives a far more consistent result than milling on fine features, and it is the usual route for heat-spreader profiles.
How CNC Honing Tungsten Copper Works
Abrasive media or tooling refine the Tungsten Copper surface in controlled stages, removing the previous step's marks until the target roughness and edge condition are reached.
We start from your supplied geometry and tolerance scheme. The setup is designed to minimise re-clamping, which protects positional accuracy across features. A first article is verified against the drawing before the balance of the batch is released.
Achievable Tolerances for CNC Honing Tungsten Copper
| Feature | Standard | Precision |
|---|---|---|
| Surface roughness | Ra 0.8 µm | Ra 0.05 µm |
| Edge break | 0.1–0.3 mm | 0.05 ±0.02 mm |
| Material removed | 0.02 mm | 0.005 mm |
| Bore roundness after honing | 0.005 mm | 0.002 mm |
| Cross-hatch angle | 45° ±10° | 45° ±5° |
| Cosmetic grade | uniform satin | mirror, no visible lines |
| Masking of datum faces | on request | standard |
Standard is what a normal quotation assumes. Precision is available on nominated features and is priced separately, because it needs extra setups, in-process gauging and CMM verification. Call out only the features that need it — blanket-tightening a drawing is the single most common reason a quote comes back expensive.
CNC Honing Quality & Inspection
Quality is built in, not inspected on. We monitor key features during the run and confirm them at final inspection, with CMM verification available for tight tolerances. We provide the inspection and traceability records your quality system requires.
Design Tips for CNC Honing Tungsten Copper
Small design adjustments often cut cost and lead time. Telling us the target Ra, the cosmetic faces and any masking needs lets us finish Tungsten Copper efficiently without over-processing. If you send your model early, we will return practical DFM feedback before you commit to production.
Working with Tungsten Copper
Tungsten Copper is combines tungsten strength with copper conductivity. We translate those properties into a process plan: the right tooling, speeds, feeds and fixturing for the alloy.
Where the grade, temper or heat-treat condition matters to performance, we confirm it with you and can supply material certificates. Material is procured to recognised standards for consistent, repeatable results.
CNC Honing Tolerances & Surface Finish
Finishing brings Tungsten Copper to a defined roughness target — from a uniform satin to Ra values as low as 0.05 µm — with controlled, repeatable edge breaks.
The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.
Secondary Operations & Finishing
Most Tungsten Copper parts need some finishing, which we manage in-house or through vetted partners. Options include deburring and edge-breaking, heat treatment, surface grinding, polishing, and plating or anodising for corrosion resistance and appearance. Give us the finished-part requirement and we will sequence every operation correctly.
Applications of CNC Honing Tungsten Copper
Tungsten Copper parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.
How to Order CNC Honing Tungsten Copper
Starting your project takes one email. Send your CAD or 2D drawing, the Tungsten Copper grade and condition, the quantity and any finish or inspection requirements. We respond quickly with price, lead time and any DFM notes, in clear English.

What We Need to Quote CNC Honing Tungsten Copper
- GeometrySTEP or IGES for the 3D model, plus a PDF drawing if you have tolerance callouts. A dimensioned sketch is enough to start.
- MaterialThe exact Tungsten Copper grade and condition — temper, heat-treat state or hardness. If you are not sure, tell us the function and we will suggest one.
- QuantityPrototype count and the expected annual volume. Both change how the part is made and therefore what it costs.
- TolerancesWhich features are critical. Everything else runs to our standard tolerance, which is what keeps the price sensible.
- FinishSurface treatment, cosmetic requirements, and any faces that must be masked.
- DocumentsWhether you need a material certificate, dimensional report, FAIR or PPAP with the shipment.
Missing something from the list is not a problem — send what you have. We will come back with the specific questions rather than a generic form.

Request a QuoteFrequently Asked Questions
What material thickness or size range suits CNC Honing Tungsten Copper?
We machine Tungsten Copper across a broad size range; share your part envelope for confirmation.
Does CNC Honing Tungsten Copper require dedicated tooling?
Most Tungsten Copper finishing work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What surface finish is achievable on Tungsten Copper with CNC Honing?
Our finishing processes refine Tungsten Copper surfaces to Ra values as low as 0.05 µm for cosmetic or sealing faces.
How clean are the edges produced by CNC Honing on Tungsten Copper?
Our deburring leaves Tungsten Copper with a consistent, controlled edge break and burr-free surfaces.
