Published typical values for C51000. Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.
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 Cylindrical Grinding
C519 Phosphor Bronze behaves predictably under CNC Cylindrical Grinding once parameters are dialled in: machinability is good; springy with excellent fatigue life, and we tune the operation accordingly.
We hold reference parameters for this grade, so repeat orders of C519 Phosphor Bronze run consistently from one batch to the next.
Achievable Tolerances for CNC Cylindrical Grinding C519 Phosphor Bronze
| Feature | Standard | Precision |
|---|---|---|
| Size (OD, ID, thickness) | ±0.005 mm | ±0.002 mm |
| Flatness over 100 mm | 0.010 mm | 0.003 mm |
| Parallelism | 0.010 mm | 0.003 mm |
| Roundness | 0.005 mm | 0.002 mm |
| Squareness | 0.010 mm | 0.005 mm |
| 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 Cylindrical Grinding 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 C519 Phosphor Bronze part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
CNC Cylindrical 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.
Final tolerances are governed by the material's behaviour, wall thickness and overall stiffness. We give honest DFM feedback if a callout would be costly or better achieved another way.
Why C519 Phosphor Bronze?
C519 Phosphor Bronze is chosen when a part needs what this grade offers — it is springy, low-friction and corrosion-resistant. We confirm the grade and any temper or heat-treat condition with you before machining.
Secondary Operations & Finishing
Finished C519 Phosphor Bronze 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.
Design Tips for CNC Cylindrical Grinding C519 Phosphor Bronze
We are happy to suggest design tweaks that improve manufacturability. 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.

What We Need to Quote CNC Cylindrical 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.
