Gr 7

Valves are devices that control or regulate the flow of fluids or other substances and ensure one-directional flow. These valves may be hydraulic, pneumatic, motor or manual. Titanium Gr 7 Valves are made of a titanium containing alloy, as the name suggests. Grade 7 is a particular grade or type of titanium. Grade 1, 2, 3,4,11 and 12 are the other grades available.


Some of the important properties of grade 7 titanium are as follows:

  • It has a density of about 4.5 g/cc
  • Its Poisson ratio is approximately 0.37
  • Its heat of fusion is 325 J/g and its melting point is around 1665°C (maximum)
  • It is considered to be a good conductor with very less electrical resistivity.


Application of Titanium Gr 7 valves:

  • Titanium Gr 7 Valves are mainly used in chemical plants, for the development of different tools and instruments.
  • It is used in the production of corrosion resistant articles.


Grade 7 alloy of titanium is said to be equivalent to grade 2 in terms of physical and mechanical properties. It is also believed to have the best Weld ability and farcicality among all the alloys or grades of titanium.
