Drawing-specified beryllium copper machining
C175 Beryllium Copper CNC Machining
We manufacture custom CNC-machined components to customer drawings and specifications. Before accepting a C175 project, we review the exact alloy and temper, material availability, machining requirements, occupational health controls, and inspection criteria.
“C175” alone is not a complete purchasing specification. We do not select or substitute a grade or temper without your approval, and we do not promise unverified material performance.
Material
Confirm exact designation and condition
Process
Review geometry, risks, and route
Acceptance
Align inspection to your criteria
Start with the specification
C175 is not a complete material callout
We confirm the alloy designation and governing material standard before planning production. C17500 and C17510 are distinct alloy designations with different compositions; neither should be assumed from a general reference to “C175.” C17200 is also a separate alloy and is not an interchangeable substitute.
If your drawing specifies a material condition, certification, or source, include it in your RFQ. We will raise apparent conflicts between design requirements and the specified condition for your engineering review.
Material identity
- Exact alloy designation and applicable material standard
- Required temper or condition
- Approved material source and substitution restrictions
Performance & documentation
- Required mechanical, electrical, or other properties
- Material certification and traceability requirements
- Any specified heat treatment or additional processing
We assess the specified material condition against your functional requirements.
We do not infer or guarantee finished-part performance from an alloy name alone. Required properties must be supported by the applicable material specification, condition, and your acceptance criteria.
Machining capabilities
We select the route against the drawing
Our listed equipment includes CNC milling centers, CNC lathes, turn-mill machines, and Swiss-type lathes. Final process suitability and capability must be reviewed against geometry, tolerances, quantity, material condition, and inspection plan.
CNC milling
For custom milled features and components.
CNC turning
For turned profiles, shafts, sleeves, pins, and bushings.
Turn-mill machining
For parts combining turned profiles with milled features.
Swiss-type machining
For evaluation of small-diameter and other suitable components.
Equipment specifications are not a guarantee of achievable part tolerances. We review final capability against the drawing and project requirements.
Surface quality & inspection
Define finish and acceptance before production
We review critical dimensions, tolerances, features, and surface-finish callouts before selecting a machining route. Please state requirements for roughness, edge condition, burr control, cosmetic appearance, and any post-machining treatment on the drawing or in the project specification.
We establish inspection against your drawing and acceptance criteria. Specific reports, records, and documentation should be agreed during quotation and order review.
Available inspection resources
- CMM: three-dimensional dimensions and geometric features
- Optical measurement: profiles, hole positions, and dimensions
- Dimensional instruments: micrometers, height gauges, and gauges
- Surface and hardness: roughness and hardness testing equipment
- Thread verification: thread plug and ring gauges for specified threads
Occupational health & safety
Safety is part of our project evaluation
Machining beryllium-containing alloys requires attention to occupational health and safety. Solid material and machining-generated dust or fine particles do not present the same exposure conditions.
We review the material and process information, potential machining risks, required controls, and applicable workplace health and safety requirements before accepting a C175 project. Cutting, deburring, grinding, polishing, cleaning, and other operations must be evaluated for potential exposure and controlled in accordance with applicable regulations and material safety information.
We do not assume routine controls are sufficient for every operation or jurisdiction. Any required handling, containment, ventilation, cleaning, waste management, or exposure-control measures must be addressed before production. Please share customer EHS requirements, restricted-process requirements, and compliance documentation expectations. Acceptance depends on confirming that necessary controls can be met.
Quality systems
Quality review for custom components
Our quality management systems are certified to ISO 9001, ISO 13485, AS9100D, ISO 14001, and IATF 16949. Certification applicability depends on the project and relevant certification scope, which we can review during supplier qualification.
ISO 9001
Certification scope reviewed for project applicability.
ISO 13485
Certification scope reviewed for project applicability.
AS9100D
Certification scope reviewed for project applicability.
Tell us your required sampling plan, inspection records, material documentation, traceability, and customer-specific quality requirements. We will confirm what can be provided during project review.
Quotation readiness
Is C175 CNC machining a fit for your project?
We can evaluate prototype, repeat-order, and production requirements subject to project scope and process suitability. Clear material identity, component requirements, and acceptance criteria help us assess supply, machining feasibility, risk controls, and inspection needs before quoting.

- Current drawing with dimensions, tolerances, and surface-finish requirements
- Material certification, traceability, source, and substitution requirements
- Quantity, order frequency, and target delivery schedule
- Inspection, documentation, and customer qualification requirements
- Applicable occupational health, safety, and environmental requirements
- Restrictions on material sourcing, substitution, or processing
Project review questions
What we confirm before proceeding
Request a C175 machining review
Send us the complete specification, drawing, and project requirements
We will review the specified grade and temper, material-supply requirements, machining route, safety considerations, and inspection criteria before confirming whether we can support the project.
For an efficient review, include your current drawing, material standard, quantity, acceptance criteria, and any EHS or customer qualification requirements.
