Spring temper is destroyed by heat. Contacts and spring fingers are etched or wire-EDM cut, never laser cut.
Machining C519 Phosphor Bronze with CNC Surface Grinding
When grinding C519 Phosphor Bronze, machinability is good; springy with excellent fatigue life. Our process plan reflects this so the finished part holds its tolerances without distortion or poor finish.
Documented parameters for C519 Phosphor Bronze mean predictable cycle times and stable, repeatable results.
Achievable Tolerances for CNC Surface Grinding C519 Phosphor Bronze
| Feature | Standard | Precision |

| Surface finish | Ra 0.4 µm | Ra 0.1 µm |
| Workpiece hardness | up to 62 HRC | up to 65 HRC |
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 Surface Grinding 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 Surface Grinding C519 Phosphor Bronze
Small design adjustments often cut cost and lead time. Allowing adequate grind stock, specifying realistic flatness over the true datum, and relieving corners help us hit tight tolerances on C519 Phosphor Bronze efficiently. If you send your model early, we will return practical DFM feedback before you commit to production.
Why C519 Phosphor Bronze?
Customers select C519 Phosphor Bronze for CNC Surface Grinding because it is springy, low-friction and corrosion-resistant. We handle grade verification and any required heat treatment or finishing.
CNC Surface Grinding Tolerances & Surface Finish
Ground C519 Phosphor Bronze reaches single-micron tolerances on size, flatness and parallelism, with surface finishes down to Ra 0.1–0.4 µm — and a near-mirror finish on suitable alloys.
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.
Secondary Operations & Finishing
Most C519 Phosphor Bronze 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 Surface Grinding C519 Phosphor Bronze
C519 Phosphor Bronze parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.

What We Need to Quote CNC Surface Grinding C519 Phosphor Bronze
- 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 C519 Phosphor Bronze 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.
