ASTM B702-93(2024) — Copper–Tungsten Electrical Contacts
Procurement reference for powder-metallurgy copper–tungsten electrical contact components within the standard’s limited scope.
Edition control: Active; ASTM B702-93 reapproved in 2024. This original MNK-G.S.A summary does not reproduce or replace the protected ASTM publication. Confirm the current authorised edition and governing order documents before use.
Scope in Procurement
ASTM B702-93(2024) covers copper–tungsten electrical contact components made by powder-metallurgy procedures. The standard uses inch-pound units only; it does not include another unit system.
The chemical composition and qualification testing are agreed between manufacturer and user, with tests selected for the contact component. Physical-property qualification uses production parts where practicable or applicable.
The specification must not be extended automatically to every WCu heat sink, EDM electrode, block, rod or custom part. Uses outside electrical contacts may require a customer specification or another documented route.
| Product context | Copper–tungsten electrical contact components |
| Manufacturing context | Powder metallurgy |
| Procurement role | Composition and function-led qualification control |
| Scope boundary | Not a universal specification for all WCu products or applications |
Where This Standard Fits
- Copper–tungsten electrical contact inquiries

- Aligning composition and physical-property testing
- Separating electrical-contact compliance from thermal-management or EDM supply
Ordering and Document Controls
- Exact ASTM designation and active edition
- Copper–tungsten composition required by the user
- Contact geometry, function and service conditions
- Manufacturing route and production-part qualification
- Required physical, electrical and mechanical evidence
- Inspection documents, traceability and delivery destination
