1、 Core material characteristics

1. High strength and lightweight

TC4 has a tensile strength of ≥ 895MPa, a density of only 4.43g/cm ³, and a specific strength three times that of stainless steel. It is suitable for reducing the weight of aircraft skeletons by more than 40%.

TA19 improves high-temperature performance by high zirconium/molybdenum content, with a strength retention rate of over 90% at 600 ℃, and is used for aircraft engine blades.

2. Extreme environmental stability

Low temperature brittleness resistance: TA9 titanium rod has a fracture toughness of ≥ 70MPa · m ¹/² in liquid hydrogen environment at -196 ℃, ensuring the structural safety of rocket fuel storage tanks.

Deep sea corrosion resistance: Ti80 is specially developed for deep sea equipment, with a 25% increase in compressive strength compared to TC4 and optimized hydrogen embrittlement resistance.

Radiation resistance: The neutron absorption cross section of zirconium alloy rods used in nuclear power is reduced by 15%, and the nuclear fuel cycle is extended to 24 months.
