Assess a specified copper, brass or bronze part with Jaquent. Identify the exact alloy and condition, functional contact or sealing faces, edge requirements and plating before machining and inspection are quoted.
Jaquent reviews copper-family parts such as fittings, terminals, contact components, rings and sleeves. The route depends on the specified alloy and condition, geometry, functional surfaces and finish. Copper, brass, bronze and nickel silver are different material families; they are not automatic substitutes.
If conductivity, thermal transfer, sealing or spring behavior drives the part, state the requirement and the documentation needed to verify the material. C110 / ETP is not an oxygen-free copper specification. Where oxygen-free stock or a particular conductivity is required, identify the exact specification and confirm the supply evidence.
Confirm plating and masking on functional faces, burr limits and any required restricted-substance declaration before quotation. Material names or photographs do not establish those requirements. For an undecided material, use the CNC material selection guide.
For material context, Wieland’s C36000 data sheet identifies a leaded free-machining brass. State any composition restrictions and required declarations for the specified alloy before release.
Specify the actual copper grade, supplied condition and any conductivity or material-record requirement. Review soft-face protection, chip removal and final contact geometry.
Review the specified brass grade for fitting, connector or threaded geometry. Material composition and any requested declarations must match the project specification.
Confirm the bronze grade, condition and required elastic or wear behavior. Thin regions, workholding and final measurement state need part-specific review.
| Specified family | Functional input | Machining questions | Acceptance input | Records and finishing |
|---|---|---|---|---|
| C110 / ETP copper | Required electrical or thermal function and exact material specification | Soft-face protection, chips, flatness and temperature | Critical faces, roughness, edge condition and final fit | Confirm material records and any plating/masking |
| C360-class brass | Exact brass grade, thread/fit function and composition requirements | Accessible features, cosmetic surfaces and burr removal | Thread class, dimensions and finished state | Confirm requested declarations and plated dimensions |
| Phosphor bronze | Grade, supplied condition and elastic or wear duty | Thin sections, support and movement after unclamping | Functionally relevant geometry and inspection state | Confirm stock, records and contact-surface treatment |
| Nickel silver | Exact specification and intended service environment | Stock form, geometry and finish | Project-specific requirements reviewed through DFM | Availability and documents confirmed before ordering |
Ductile copper can form persistent chips and built-up material at the cutting edge. Review tool geometry and chip evacuation for deep features, and identify contact faces that must be protected during machining and handling.
Temperature and stress released during material removal can affect long bars and broad contact faces. Identify flatness and fit requirements, and agree the state in which those features will be measured.
Identify functional contact or sealing surfaces and the required burr and cleanliness condition. Agree deburring, protected handling and any specific evaluation needed for those faces.
Thin spring or sleeve features can recover after unclamping. Specify the functional geometry and the free or supported state for acceptance; review support and finishing strategy against that requirement.
The drilling image and representative rings and fittings provide process and geometry context. They do not establish an alloy certificate, a conductivity result or a named customer project. Confirm exact material, functional-surface requirements and records in the quotation.
Soft contact faces, thin sections, workholding and the specified plating can affect final copper-alloy geometry. Identify critical faces and the required acceptance state.
Apply individually specified requirements and any general drawing tolerance to their stated scope and edition. Where neither applies, ±0.10 mm is a common quotation basis. Selected milling or turning features may be reviewed to ±0.01 mm. For a five-axis route, designated critical features may be reviewed to ±0.005 mm where material and geometry allow, confirmed through DFM. Swiss-turned linear features and critical wire EDM features have their own process-specific references; confirm the applicable service and feature rather than transferring one figure to every operation.
Pre-shipment inspection at the authorized manufacturing facility follows the drawing and agreed plan. Every-part checks apply to named features when specified; other checks can follow agreed sampling. Request material records, traceability, dimensional reports, customer FAI forms or a CoC in the quotation, with coverage and format confirmed. See functional tolerances and GD&T and inspection scope and required records.
Deburring, polishing, lacquer, and nickel, tin, or silver plating are available or coordinated per project. Specify conductive contact faces, coating thickness, masking, and surface-roughness requirements. Hardware install can ship with the same order when specified. Details: CNC surface finishes.
