Dingding Titanium Industry: High performance titanium alloy solutions for the aerospace industry

The demand for "lightweight, high strength, high temperature resistance, and corrosion resistance" in aerospace equipment is driving continuous breakthroughs in material technology. As a national high-tech enterprise rooted in the "China Titanium City", Baoji Dingding Titanium Products Co., Ltd. relies on more than 20 years of experience in titanium material research and development and production, and creates aerospace specific titanium alloy rods, plates, wires and other products with military grade standards. They are widely used in key fields such as aircraft structural components, engine components, and spacecraft components, providing reliable material support for the aerospace industry.

1、 Focus on three core aerospace scenarios and accurately match equipment requirements

Based on a deep understanding of aerospace industry standards, the company customizes differentiated high-performance titanium alloy solutions to meet the performance requirements of different equipment, ensuring perfect compatibility between materials and equipment functions.

1. Titanium alloy for aircraft structural components: a perfect balance between lightweight and strength

The structural components of aircraft fuselage frames, wing beams, landing gear, etc. need to bear huge loads while reducing their own weight. The problems of fatigue and heavy steel in traditional aluminum alloys urgently need to be solved. The core pain points of customers in the aerospace industry are concentrated on "insufficient specific strength, poor fatigue resistance, and long processing cycles". Dingding Titanium Industry provides exclusive solutions based on aerospace grade titanium alloy grades such as TC4, TC11, and TA15

In response to the demand for "lightweight and weight reduction" of aircraft structural components, high-purity sponge titanium raw materials are used to produce TC4 titanium alloy rods through the "three time vacuum self consumption melting" process, with a tensile strength of 950MPa and a yield strength of ≥ 860MPa. The specific strength is 1.8 times that of high-strength steel, which can reduce the weight of structural components by 30% -40% and significantly reduce aircraft fuel consumption. For components such as wing beams that are subjected to alternating stress, the microstructure is optimized through the "isothermal forging+aging treatment" process, which increases the fatigue life of titanium alloy to more than 10 ^ 7 times, far exceeding the standard requirements of the aviation industry.

In response to the "ultra-high strength" requirements of key load-bearing components such as landing gear, TC11 titanium alloy plates are customized. After special heat treatment, the tensile strength exceeds 1100MPa while maintaining an elongation rate of over 12%, avoiding the risk of brittle fracture in low-temperature environments. We can customize titanium alloy rods with a diameter of 5-200mm and titanium alloy plates with a thickness of 2-50mm according to customer drawings, with dimensional tolerances controlled within ± 0.03mm, reducing subsequent machining and shortening equipment production cycles.

2. Titanium alloy for aircraft engines: breakthrough in both high temperature resistance and corrosion resistance

Aircraft engine compressor blades, casings, and other components work in a high-temperature and high-pressure gas environment of 300-600 ℃ for a long time, facing two core pain points of "high-temperature strength attenuation and gas corrosion". Dingding Titanium Industry has developed targeted high-temperature resistant titanium alloy series products such as Ti-6Al-4V ELI and TC17, providing precise solutions:

By adopting advanced technology of "electroslag remelting+directional solidification", the tensile strength of titanium alloy remains above 800MPa at high temperature of 600 ℃, and the high-temperature endurance strength reaches 400MPa/100h, far superior to ordinary titanium alloy. By surface aluminum silicon coating treatment, the corrosion rate in high-temperature gas environment is less than 0.008mm/year, solving the industry problem of "high-temperature corrosion failure" of engine components.

In response to the demand for "precision forming" of compressor blades, the titanium alloy rod provided has an internal grain size grade of 5 or above, without defects such as looseness or inclusions, and supports precision forging and five axis milling. It has provided customized materials that comply with GJB 2744A standards for multiple aviation engine enterprises, helping to improve their product performance.

3. Titanium alloys for spacecraft: stable and reliable in extreme environments

Spacecraft skins, rocket fuel storage tanks, satellite structural components, etc. need to withstand severe vibrations during the launch phase, extreme temperature differences in space (-180 ℃ to 150 ℃), and space radiation environments, with strict requirements for material "high and low temperature stability, anti vibration fatigue, and no magnetic interference". This is precisely the core concern of customers in the aerospace industry, and Dingding Titanium Industry's solution is as follows:

Customized TA7 titanium alloy sheet has an impact toughness of ≥ 80J/cm ² at -180 ℃ and a mechanical property degradation rate of less than 5% at 150 ℃, accurately adapting to extreme temperature differences in space. In response to the "high-pressure sealing" requirements of rocket fuel storage tanks, the weld strength of Ti-3Al-2.5V titanium alloy wire welding reaches over 95% of the base material, and the leakage rate of air tightness testing is less than 1 × 10 ^ -9 Pa · m ³/s, which meets the aerospace grade sealing standards.

The non-magnetic titanium alloy products provided for satellite structural components have a magnetic permeability of ≤ 1.003, which avoids interference with satellite navigation and communication systems, and has excellent radiation resistance performance to ensure the stability and reliability of satellites during space service.
