Machining materials
Select material by function, finish and inspection risk.
A material name alone is not enough. The alloy or grade, condition, certificate requirement, finish and mating environment all affect the manufacturing plan.

Material definition
Specify the exact grade and condition
Equivalent-looking materials can behave differently during machining, finishing and service. A complete RFQ identifies the standard, grade and any certificate or traceability expectation.
- Alloy, grade, temper or heat-treatment condition
- Customer-approved equivalents, if any
- Material certificate and lot requirements
- Environmental and mating-material considerations
Finish compatibility
Consider surface treatment before features are finalized
Coating thickness, masking, passivation, cosmetic zones and contact surfaces can affect dimensions and inspection. Define them on the drawing instead of leaving them to a purchase-order note.
- Finished versus pre-finish dimensions
- Masked threads and electrical contacts
- Cosmetic surface classification
- Post-finish inspection requirements
Questions buyers ask
Technical answers before the RFQ.
Can I request a material equivalent?
List acceptable standards or request a documented proposal. Substitution should never be assumed.
Should material certificates be requested at RFQ stage?
Yes. Certificate and lot-traceability requirements can affect sourcing, cost and lead time.
