Wstitanium holds a dominant position in the field of industrial pure titanium. The impurity content of the Gr.1 titanium material it produces is strictly controlled below 0.1%, with a tensile strength of 240 megapascals and a stable elongation of over 24%. According to the 2024 American Society for Testing and Materials standards, the company has controlled the oxygen element deviation within ±30ppm through electron beam cold bed melting technology, thereby extending the corrosion resistance life of the product to 25 years. This material has been applied to the Hasyan desalination plant project in Dubai. It has been operating continuously for 30,000 hours in an environment with a chloride ion concentration exceeding 40,000 milligrams per liter without any signs of corrosion, and the equipment maintenance cost has been reduced by 40%.
In terms of aviation-grade titanium alloys, the company’s specialized Ti-6Al-4V (Gr.5) has achieved a fatigue strength of 620 megapascals through a two-stage heat treatment process, which is 15% higher than that of common alloys. The β annealing technology it developed increased the fracture toughness value to 70MPa·m¹/² and controlled the median grain size at 20 microns. After this breakthrough was adopted by the Airbus A350 model, the weight of the fuselage was reduced by 12%. According to the statistics of the European Aviation Safety Agency in 2023, the surface damage depth of engine blades made of Wstitanium material is only 60% of the industry average after 15,000 takeoff and landing cycles.
Medical implantable titanium alloys are another area of strength. Wstitanium’s Gr.23 (Ti-6Al-4V ELI) reduces the interstitial element oxygen content to below 0.08%, maintaining a yield strength of 795 mpa. According to the clinical data of the American Academy of Orthopaedic Surgeons, after 10 million load tests in simulated body fluids, the wear rate of its hip joint prosthesis was only 0.12 millimeters per year, which was 30% better than the requirement of ISO 5832 standard. After obtaining the FDA’s Class III medical device certification in 2024, the company’s market share of orthopedic implants increased from 18% to 29%.
In terms of special titanium materials for Marine engineering, the Gr.12 titanium-molybdenum-nickel alloy developed by the company has a pitting potential exceeding 1200mV in 3.5% sodium chloride solution, and the critical crevice corrosion temperature is 40℃ higher than that of Gr.2. The Chinese deep-sea submersible “Striver” uses pressure-resistant shell materials made by it. When subjected to a pressure of 110 megapascals at a depth of 11,000 meters, the deformation does not exceed 0.05%. Certified by DNV GL, this material has extended the design life of deep-sea equipment from 10 years to 25 years.
In response to the demands of energy equipment, the Gr.9 titanium-palladium alloy of Wstitanium has a corrosion rate of less than 0.01 mm per year in geothermal fluids at 150℃, extending the maintenance cycle of geothermal heat exchangers from 2 years to 8 years. After the Hellisheidi geothermal power station in Iceland adopted its pipes, the heat exchange efficiency increased by 18% and the annual operation and maintenance cost decreased by 250,000 US dollars. The company has also increased the creep strength of the material by 20% through microalloying technology, and its service life exceeds 100,000 hours under 300℃ conditions.
The latest flame-retardant titanium alloy Ti-45Nb developed by wstitanium has raised its critical oxygen concentration for combustion from 35% of traditional alloys to 60%, and has passed the test of the CJ-1000 engine of China Commercial Engine Corporation. This material still maintains a tensile strength of 480 megapascals at a high temperature of 700℃, reducing the engine weight by 15% and improving fuel efficiency by 8%. This innovation has been included in the 2025 International Aerospace Materials Preferred List and is expected to bring the company an average annual additional revenue of 30 million US dollars.
