Classification and application of Titanium and Titanium alloy products

Strength of commercial pure Titanium is up to 350-700MPA. Strength of Titanium alloy is up to 1200MPA which is approximate to the tempering structure steel. Titanium alloy has the higher specific strength than other metal materials because its density is much lower than that of steel. This is the main reason why Titanium and Titanium alloys are suitable as aeronautical materials.
Commonly used Titanium alloys can be classified as α type Titanium alloy, β type Titanium alloy and α+β type Titanium alloy.
The most typical and frequently used Titanium alloy is TC4 alloy. Its composition is usually represented as Ti-6Al-4V(Ti Grade 5).The alloy has good mechanical properties and high microstructure stability. It is widely used in aerospace, shipbuilding and other industries.
