Frequently Asked Questions

What is Grade 9 titanium used for?
Grade 9 (Ti-3Al-2.5V, UNS R56320) is a 'half-alloy' with strength between CP and Grade 5. It's the go-to grade for thin-wall tubing: bicycle frames, aerospace hydraulic lines, and sports equipment. Better cold formability than Grade 5 makes it ideal for drawn tube applications.
