Titanium Grade 5 has good tensile properties at ambient
temperature and a useful creep resistance up to 300oC
(570oF). Resistance to fatigue and crack propagation is
excellent. Like most titanium alloys, Grade 5 has
outstanding resistance to corrosion in most natural and many
industrial process environments. The ability to age harden
this alloy makes it a good choice for such applications as
springs and fasteners.
Applications include:
- Aerospace
- Surgical Implants
- Jewellery
- Chemical
- Springs
- Bolts
- ...and various other fasteners
