TIMET — timetal-15-3-3-3 ↗Retain and rewrite. TIMET describes it as alpha/beta; the palladium-bearing Grade 18 variant is separate.
- Correct the old near-alpha classification and unsupported '25% stronger' and universal better-machining comparisons.
- Remove the untraceable generic machining recommendation (32 %) and cutting-speed ranges; select machining data by actual material condition, tool and operation.
- The old O maximum 0.12% differs from the reviewed TIMET Grade 9 table 0.15%; do not publish the old composition as a governing acceptance table.

Primary source records
TIMET — timetal-3-2.5 ↗Retain and rewrite. The public producer-sourced abstract establishes identity; historical ELI cryogenic research cannot qualify all normal-grade stock.
- Remove universal 790 MPa/30 HRC and unqualified cryogenic suitability; current mechanical specification remains a gap.
- Remove the untraceable generic machining recommendation (20 %) and cutting-speed ranges; select machining data by actual material condition, tool and operation.

ASM Alloy Digest — Ti-5Al-2.5Sn, producer TMCA ↗
NASA — historical Ti-5Al-2.5Sn ELI investigation ↗Retain and rewrite. Sheet and bar/forging heat-treatment routes differ; the reviewed producer chemistry includes silicon limits that must be checked against the actual specification.
- Remove the unverified ASTM Grade 19 mapping. The old Si range 0.08–0.25% also differs from the reviewed TIMET table 0.06–0.13%; preserve the exact procurement specification instead of combining them.
- Remove one 1000 MPa strength and universal 400°C service claim; do not infer a maximum operating temperature from a summary.
- Remove the untraceable generic machining recommendation (18 %) and cutting-speed ranges; select machining data by actual material condition, tool and operation.

Primary source records
TIMET — timetal-6242 ↗Retain and rewrite. Its microstructure and properties depend on thermo-mechanical history; Grade 23 ELI is separate.
- Remove universal 950 MPa and the '45% lighter at comparable strength' shortcut without a matching design basis.
- Remove the untraceable generic machining recommendation (22 %) and cutting-speed ranges; select machining data by actual material condition, tool and operation.
Evidence: Identity / state reference. Current live page: read. Local preview: 200, noindex. Production unchanged.
Primary source records
TIMET — timetal-6-4 ↗Retain and rewrite. ELI has tighter interstitial limits than Grade 5; it is not automatically implant-certified stock.
- Remove 'cutting behaviour is identical' and universal 860 MPa; do not treat alloy identity as medical qualification.
- Remove the untraceable generic machining recommendation (22 %) and cutting-speed ranges; select machining data by actual material condition, tool and operation.
Evidence: Identity / state reference. Current live page: read. Local preview: 200, noindex. Production unchanged.
Primary source records
TIMET — timetal-6-4 ↗Retain and rewrite. The sheet separates a guaranteed minimum yield statement from typical mechanical data; commercially pure does not mean chemically pure.
- Do not present 345 MPa as a universal tensile value or 180 HV as all supplied Grade 2 stock.
- Remove the untraceable generic machining recommendation (40 %) and cutting-speed ranges; select machining data by actual material condition, tool and operation.
- The old carbon maximum 0.10% differs from the TIMET 50A sheet 0.08%; replace the unsourced chemistry table with the identified source/specification route.
Evidence: Identity / state reference. Current live page: read. Local preview: 200, noindex. Production unchanged.
Primary source records
TIMET — timetal-50a ↗Retain and rewrite. TIVAR 1000 virgin stock is a named example. Reprocessed, antistatic, lubricated and other modified UHMW grades need their own identity and data.
- Remove will not break under impact and highest abrasion resistance of any thermoplastic.
- A no-break test outcome concerns a particular specimen/method; ISO and ASTM datasheet columns are not unit conversions.

Primary source records
- Mitsubishi Chemical Advanced Materials TIVAR 1000 Virgin UHMW-PE
Mitsubishi Chemical Advanced Materials TIVAR 1000 Virgin UHMW-PE ↗Retain and rewrite. The cited W1 product is cold-drawn water-hardening drill rod with a supplier-specific carbon range; it does not establish every W1 product variant.
- Do not treat a commercial drill-rod carbon band as every W1 composition or assign one final HRC to all section sizes.
- Withdraw the legacy generic hardness (190–220 HB (annealed)) and tensile-strength (1,380 MPa (200 ksi) hardened) pair: the old page does not establish a matching product, heat treatment, section and test source.
- Remove the unsupported cutting-speed table and machinability percentage; select tooling only after the actual material condition is known.

Primary source records
- Buffalo Precision AISI W1 drill rod
Buffalo Precision AISI W1 drill rod ↗Retain and rewrite. Age-hardenable nickel superalloy; VIM/VAR and VIM/ESR routes and subsequent heat treatment are specified for the application. Rotating-part duty and general hot service are different cases.
- Replace the old blanket 760 °C service claim with application-specific time, stress and treatment requirements.
- Remove unsupported legacy machining percentages and generic cutting-speed tables.

Special Metals: Waspaloy technical bulletin ↗Retain and rewrite. Compare exact POM-H / POM-C / PA66 products and conditioning; link shared property facts to their material records.
