Grade 9 titanium alloy is an α-type titanium alloy with a nominal composition of Ti-3Al-2.5V, developed for cold-workable tubing applications. Its strength at room and high temperatures is 20%-50% higher than pure titanium, and its weldability and cold-forming properties are superior to TC4 alloy. The maximum operating temperature is approximately 315℃. Improving its strength through targeted heat treatment (age hardening) is virtually impossible. Its already excellent corrosion resistance can be further enhanced by adding small amounts of Pd (0.05%) or Ru (0.1%). Although its strength is not as high as TC4 alloy, its excellent cold-working properties make it widely used.
Typical Applications
Titanium Frames for Cycle, Bicycle tubing, Exhaust pipes, Tubing for Bikes, Marine engineering
Excellent resistance to general corrosion in seawater applications

Resistant to stress corrosion cracking in chloride and sour gas environments
Excellent resistance to pitting, crevice and erosion corrosion
Good formability and weldability
Very low thermal expansion
Excellent fatigue properties from Sandvik's proprietary processing that controls crystal texture
