Titanium plate is a high-performance sheet material made from titanium and titanium alloys through multiple precision machining processes. With its core advantages of "lightweight, high strength, corrosion resistance, and heat resistance", it has become a key material in the high-end manufacturing field. Its brand system is rich, with national standards covering TA1, TA2, TC4, TA15 and other series, and American standards corresponding to GR1, GR5 and other models, which can adapt to diverse needs from basic industries to cutting-edge technology.
In terms of performance, titanium plate exhibits outstanding comprehensive advantages: the density is only about 4.5g/cm ³, which is about 60% of steel, while the specific strength of mainstream grades such as TC4 reaches 220 MPa · cm ³/g, which is 1.3 times that of aluminum alloy. The high temperature resistance performance is significant, and the tensile strength of TA15 at 550 ℃ is still not less than 600 MPa, far exceeding the upper limit of aluminum alloy's tolerance; The corrosion resistance is more outstanding, with a corrosion rate of less than 0.001 mm/year in salt spray environment. TA9, TA10 and other grades are more resistant to strong corrosive media such as hydrochloric acid and chloride, without the need for additional coating protection. Some grades have excellent low-temperature performance, such as TA7 which can maintain good plasticity at -253 ℃, while medical grades such as TC4 ELI have biocompatibility and no abnormal release of metal ions.
The production process strictly follows the specifications, from melting titanium ingots in a vacuum consumable electric arc furnace, to hot rolling and cold rolling finishing, followed by annealing treatment to optimize performance, and finally achieving a precision standard of Ra ≤ 1.6 μ m through surface treatment such as acid washing. The product specifications cover a wide range, with thickness extending from 0.5mm to 80mm, width up to 3m, and length up to 6000mm. It supports customization in various states such as hot working (R), cold working (Y), and annealing (M), and implements domestic and foreign standards such as GB/T 3621 and ASTM B265 to ensure stable quality.
The application scenarios span multiple fields: in aerospace, TC4 is used for fuselage skin and Ti-5553 adapted landing gear support plate, which can achieve a 30% weight reduction; TA9 titanium plate in the chemical industry is an ideal material for heat exchangers and reactors; TC4 ELI in the medical field can manufacture implants such as artificial joints; In addition, it is widely used in scenarios such as seawater desalination and new energy equipment, becoming the preferred choice for lightweight and high-performance requirements.
