Published typical values for C36000. Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.
Nothing much — this is the easiest metal in the shop. Worth asking about if a copper or bronze part is cost-driven rather than conductivity-driven.
Machining C377 Brass with CNC Punching
When punching C377 Brass, machinability is excellent (free-machining); fast speeds, clean finish. Our process plan reflects this so the finished part holds its tolerances without distortion or poor finish.
Documented parameters for C377 Brass mean predictable cycle times and stable, repeatable results.
Achievable Tolerances for CNC Punching C377 Brass
| Feature | Standard | Precision |
|---|---|---|
| Hole position across sheet | ±0.15 mm | ±0.10 mm |
| Hole diameter | ±0.10 mm | ±0.05 mm |
| Overall blank size | ±0.20 mm | ±0.10 mm |
| Minimum hole | 1.0 × thickness | 0.8 × thickness |
| Hole-to-edge distance | 2.0 × thickness | 1.5 × thickness |
| Burr height | 0.08 mm | 0.03 mm (deburred) |
| Sheet thickness range | 0.5–6.0 mm | 0.5–3.0 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.
CNC Punching Tolerances & Surface Finish
Punched C377 Brass holds hole-position repeatability around ±0.10 mm across the sheet, with consistent hole quality when punch/die clearance is matched to the gauge.
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.
CNC Punching 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.
Secondary Operations & Finishing
Most C377 Brass 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.
Design Tips for CNC Punching C377 Brass
Small design adjustments often cut cost and lead time. Keeping hole-to-edge and hole-to-hole distances at least 1.5–2× thickness avoids distortion and tearing in punched C377 Brass. If you send your model early, we will return practical DFM feedback before you commit to production.
Why C377 Brass?
Customers select C377 Brass for CNC Punching because it is free-machining with good conductivity. We handle grade verification and any required heat treatment or finishing.

Finishing Options for C377 Brass
| Finish | Thickness / effect | Why it gets specified |
|---|---|---|
| Nickel plate | 5–15 µm | Hard, bright, corrosion resistant |
| Chrome plate | 0.3–1 µm | Decorative, over nickel |
| Clear lacquer | 10–20 µm | Stops the natural tarnish |
| Tin plate | 3–15 µm | Solderable contacts |
| 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 Punching C377 Brass
- 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 C377 Brass 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.
