TC4 /Gr5 Ti-6Al-4V Titanium Alloy Sheet Titanium Block

TC4 titanium alloy is composed of Ti-6Al-4V, containing 6% α-stabilizing element AI and 4% β-stabilizing element V, which belongs to (a+b) type two-phase titanium alloy, and it is the most widely used and most productive a+β type alloy at present. TC4 titanium alloy with a long time working temperature of up to 400℃ is widely used in the manufacture of fan and compressor disks and blades of engines and important load-bearing components such as beams, joints and bulkheads of aircraft structures. Important load-bearing components such as beams, joints and spacer frames in aircraft structures.

TC4 titanium alloy main products are bars, plates, tubes and machined parts, can be used to do 450 ℃ below the use of jet engines and turbine blades and turbine discs. TC4 titanium alloy has good welding performance, can be heat-treated to strengthen the general delivery of the use of the annealed condition.

TC4 titanium alloy strength :sb=1.012MPa.

Density of TC4 titanium alloy: g=4.4*103.

Specific strength of TC4 titanium alloy: sb/g=23.5, while the specific strength of alloy steel sb/g is less than 18.

Modulus of elasticity of TC4 titanium alloy: E=110GPa, about 1/2 of steel, so titanium alloy is easy to produce deformation when processing.

TC4 titanium alloy chemical composition: TC4 containing titanium (Ti) balance, iron (Fe) ≤ 0.30, carbon (C) ≤ 0.10, nitrogen (N) ≤ 0.05, hydrogen (H) ≤ 0.015, oxygen (O) ≤ 0.20, aluminum (Al) 5.5 ~ 6.8, vanadium (V) 3.5 ~ 4.5.
