CNC Bending Nickel Silver from VT machining delivers precision Nickel Silver parts produced to your exact drawing. CNC bending forms sheet metal to precise angles using a programmed press brake and back-gauge, and we tune every parameter to the behaviour of Nickel Silver, which is corrosion resistant with a bright silver-white finish.

It is bought for its colour as often as its properties, so cosmetic faces are masked through deburring and handled in gloves from the machine onward.
How CNC Bending Nickel Silver Works
The Nickel Silver blank is bent or formed against tooling under CNC-controlled ram travel and back-gauge positioning. Bend allowance and springback are compensated in the program so finished angles hit the print.
Programming is driven directly by your 3D model or print. Work-holding, tool selection and the cutting strategy are planned around the critical features and the material before the first chip is cut. First-off inspection confirms the process is centred before production continues.
Achievable Tolerances for CNC Bending Nickel Silver
| Feature | Standard | Precision |
|---|---|---|
| Bend angle | ±1.0° | ±0.5° |
| Flange length | ±0.30 mm | ±0.15 mm |
| Hole-to-bend distance | ±0.30 mm | ±0.15 mm |
| Minimum inside radius | 1.0 × thickness | 0.8 × thickness |
| Minimum flange height | 4 × thickness + radius | 3 × thickness + radius |
| Bend-to-bend spacing | ±0.30 mm | ±0.15 mm |
| Sheet thickness range | 0.5–8.0 mm | 0.5–4.0 mm |
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.
Working with Nickel Silver
As a material, Nickel Silver is corrosion resistant with a bright silver-white finish. Our setup reflects the alloy's machinability so the finished part is accurate and free of avoidable defects.
We verify the exact grade and condition before machining, and traceable mill certs are available on request. We can work to your nominated material source or specification when required.
Secondary Operations & Finishing
Finished Nickel Silver parts can move straight into secondary operations under one roof. Typical add-ons are deburring, passivation, anodising, plating, blasting, polishing and laser marking. We coordinate the whole chain so you receive complete, inspection-ready parts.
CNC Bending Tolerances & Surface Finish
Formed Nickel Silver holds bend angles to about ±0.5° and consistent flange dimensions, with bend allowance compensated for the material and thickness.
Exact achievable figures depend on the alloy, the feature size and the part geometry. Tell us which dimensions are critical and we will advise feasibility up front.
Design Tips for CNC Bending Nickel Silver
We are happy to suggest design tweaks that improve manufacturability. Consistent bend radii, adequate flange lengths and grain-direction awareness reduce cracking and springback in formed Nickel Silver. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Bending Quality & Inspection
We control quality throughout the process, not just at the end. In-process checks plus final inspection — including CMM where specified — keep every Nickel Silver part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Applications of CNC Bending Nickel Silver
Customers order CNC Bending Nickel Silver components for everything from instrumentation to structural and functional assemblies. Whether you need a single prototype or recurring production volume, the same process discipline applies.
How to Order CNC Bending Nickel Silver
Getting a quote is simple. Share your model, the material grade, your quantity and target tolerances. You receive a clear quotation with lead time and honest manufacturability feedback.
Parts We Have Run in Nickel Silver
Three representative CNC Bending Nickel Silver jobs, with the callouts that actually drove the process plan. Yours will differ — these are here so you can judge whether your part is in our range before you spend time on an RFQ.
Sheet-metal enclosure
- Material
- Nickel Silver
- Size
- 300 × 200 × 120 mm
- Key callouts
- Bend angle ±0.5°, diagonal ±0.5 mm
- Batch
- 400 pcs
Bend sequence chosen so no flange collides with the tool on the last hit.
Chassis with countersinks
- Material

- Size
- 450 × 300 × 2 mm
- Key callouts
- Countersink depth ±0.1 mm, 6 bends

Countersinks formed before bending while the sheet is still flat and supported.
Radiused cover
- Material
- Nickel Silver
- Size
- R150 × 500 mm
- Key callouts
- Radius ±1 mm, no tool marks
- Batch

Bumped in 14 small steps rather than rolled, because the batch does not justify a roll set.
Finishing Options for Nickel Silver
| Finish | Thickness / effect | Why it gets specified |
|---|---|---|
| Deburr / edge break | 0.05–0.3 mm | All parts unless the drawing says otherwise |
| Bead blast | Ra 1.6–3.2 µm | Uniform matt finish, hides tool marks |
| Laser marking | — | Part number, lot code, data matrix |

What We Need to Quote CNC Bending Nickel Silver
- 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 Nickel Silver 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.

How clean are the edges produced by CNC Bending on Nickel Silver?
Machined Nickel Silver edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
What is the typical lead time and minimum order for CNC Bending Nickel Silver?
CNC Bending prototypes for Nickel Silver can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
Which industries use CNC Bending Nickel Silver parts?
CNC Bending Nickel Silver parts are used across aerospace, medical, automotive, electronics, semiconductor and general industrial sectors — anywhere precise Nickel Silver components are required.
Why is Nickel Silver a good choice for CNC Bending?
