KYS TITANIUMGr2 and Gr5
Gr2 is an unalloyed titanium grade; Gr5 is a Ti-6Al-4V alloy grade. Grade alone does not establish application suitability, product-standard compliance or material condition.
KYS TITANIUM
Titanium Grades
Distinguish material grade, product form and delivery condition.
| Grade / designation | Distinction and verification |
|---|---|
| Gr2 | Commercially pure, unalloyed titanium. Chemistry and mechanical requirements depend on product specification, dimensions and condition; the grade does not establish suitability for every environment. |
| Gr5 | Ti-6Al-4V alloy, distinct from unalloyed Gr2. Verify product form, condition and testing against the specified product standard. |
| Gr5 ELI | A commercial designation requiring clarification for Ti-6Al-4V ELI (extra low interstitial). The specified standard imposes tighter interstitial controls; ordinary Gr5 is not a substitute. Confirm the material designation, chemistry limits and actual records. |
| TC4 / Gr5 | A Ti-6Al-4V family comparison only. For TC4 review GB/T 3620.1 and the applicable product standard; for Gr5 review the relevant ASTM specification (for example B265 for sheet/plate, B348/B348M for bars). Compare editions, chemistry, properties, condition and inspection before accepting substitution. |
This comparison explains materials and does not add grades to KYS’s confirmed supply range. An ELI designation is not medical or implant certification.
Gr5 ELI: separate requirements
Gr5 ELI is listed separately from ordinary Gr5. A dimensional record does not establish medical suitability; verify the actual standard, condition and order requirements.
Do not assume unconditional equivalence
Cross-system comparisons require review of the edition, chemistry, mechanical requirements, product form and condition. Trade names do not replace review of actual documentation.
Information to include in an enquiry
Provide the desired grade, form, dimensions, quantity, intended use and document requirements. If the grade is undecided, describe operating conditions for further discussion.
A technical standard is not a certification awarded to KYS TITANIUM or to every product. Confirm the edition, scope and product conformity for each order.
