ASTM B890-25 — Tungsten Hardmetal XRF Analysis
Procurement reference for wavelength-dispersive XRF determination of metallic constituents in tungsten alloys and hardmetals.
Edition control: Active; ASTM B890-25. 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 B890-25 defines an XRF route for determining metallic constituent concentrations in tungsten-based alloys and hardmetals.
The method addresses representative preparation of powder and sintered material and can support acceptance to a grade specification when its material and analytical scope applies.
It is not applicable to every tungsten composite; official ASTM guidance excludes material systems that do not oxidize readily under the preparation route, including WCu, WAg and tungsten with cobalt-ruthenium binder. Exact composition family and laboratory capability must be screened first.
| Analytical method | Wavelength-dispersive X-ray fluorescence |
| Material context | Powder and sintered tungsten alloys and hardmetals |
| Procurement role | Metallic-constituent and grade-acceptance evidence |
| Scope boundary | Not applicable to every tungsten composite or binder system |
Where This Standard Fits
- ВК/ТК and other tungsten-hardmetal chemistry verification
- Powder and sintered batch analysis
- Independent or supplier laboratory report planning
- Checking whether a composite falls outside the preparation route
Ordering and Document Controls
- Exact ASTM edition and material family
- Expected metallic constituents and concentration ranges
- Powder or sintered specimen and representative sampling
- Fusion preparation and calibration standards
- Laboratory validation, results and uncertainty
- Grade specification, report identity and traceability
