Titanium Grade 5 / 6Al4V (For Springs)

Titanium Base Wire for wire springs, flat springs and wire products

Titanium Grade 5 has good tensile properties at ambient temperature and a useful creep resistance up to 300°C (570°F). 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. It can be used for any TSMC spring product such as wave springs, retaining rings and compression springs.
Titanium Grade 5 is also known as Titan Grade 5 and Allvac 6-4.

Key Features

  • Excellent strength to weight ratio
  • Higher strength at ambient temperatures than Grades 1 and 2
  • Good creep resistance up to approx 300 °C (570 °F)
  • Outstanding resistance to corrosion in most natural and many industrial process environments
  • Approximately half the density of nickel alloys
