Frequently Asked Questions

Titanium Grade 5 Round Bar is an alpha-beta titanium alloy rod containing 6% aluminum and 4% vanadium. Manufactured under ASTM B348 and AMS 4928 standards, it is the most widely used titanium alloy worldwide due to its extreme strength-to-weight ratio, high temperature tolerance, and corrosion resistance.

Titanium Grade 2 is commercially pure (unalloyed) titanium offering maximum ductility and superior corrosion resistance, but lower tensile strength (344 MPa min). Titanium Grade 5 is an alloyed grade offering almost double the yield strength (880 MPa min) for structural high-load applications, though with slightly reduced cold formability.

Yes. Titanium Grade 5 manufactured to ASTM F1472 specifications is fully certified for medical implant applications, surgical tools, and dental fixtures due to its non-magnetic properties and excellent biocompatibility.

Every shipment includes an EN 10204 3.1 Mill Test Certificate detailing heat numbers, chemical composition, mechanical test results, ultrasonic test reports, and compliance with ASTM B348 and AMS 4928 standards.

Common finishes include bright, polished, ground, pickled, and machined finishes, depending on the required dimensions, surface condition, and application.

Yes. Titanium Grade 5 can be heat treated to improve its strength and mechanical properties. Common treatments include solution treatment and aging, performed according to the applicable material specification.
