Core Material Advantages and Product Recommendations
Combining the unique properties of various special metals with the specific application requirements in the aerospace field, the following are targeted product solutions and performance guarantee descriptions:
1. Tungsten: Structural Guardian Under Extreme High Temperatures
With an ultra-high temperature resistance of over 3410℃, a high specific gravity of 19.3g/cm³, and excellent impact resistance, tungsten has become a core material for extreme high-temperature scenarios in aerospace. In terms of application scenarios, it is suitable for rocket engine nozzle throats, directly withstanding gas scouring above 3000℃; it is also used for counterweights in spacecraft inertial navigation systems and housings of high-temperature sensors. The precision tungsten rods, tungsten alloy forgings, and tungsten sheets with an accuracy of ±0.02mm produced by Baoji Yunjie Metal maintain a tensile strength of over 500MPa and an impact toughness of not less than 12J/cm² at 1600℃, ensuring no structural deformation under extreme high temperatures.
2. Molybdenum: Core Carrier for Efficient Thermal Management
Molybdenum exhibits high-temperature resistance of 1668℃, stable high-temperature strength, excellent thermal conductivity of 138W/(m·K), and good processability, playing a crucial role in aerospace thermal management scenarios. Specifically, it can be applied to guide vanes of aero-engine combustion chambers to optimize gas flow; used as thermal radiation shields for spacecraft to effectively insulate extreme temperatures; and manufactured into heating elements for high-temperature furnaces. Baoji Yunjie Metal's molybdenum alloy plates, molybdenum tubes, precision molybdenum foils with a thickness of 0.05-0.5mm, and various molybdenum special-shaped parts have a creep rate of only 0.02%/1000h at 1200℃, and their thermal conductivity is 3 times that of stainless steel.
3. Niobium: Dual Responsibility for Lightweight and Radiation Resistance
Niobium possesses excellent high-temperature toughness, and its lightweight density of 8.57g/cm³ gives it obvious advantages. It also has excellent radiation resistance and corrosion resistance to liquid metals. Its application scenarios include skin support structures of hypersonic vehicles; used as pipelines for nuclear thermal propulsion systems; and spacecraft reactor shielding components. The niobium alloy rods, niobium plates, and processed parts produced by Baoji Yunjie Metal have a tensile strength of ≥350MPa at 1000℃ and an elongation of over 20%, with no cracking risk in temperature cycles from -200℃ to 1500℃.
4. Titanium: Benchmark Material for Aerospace Lightweight
Titanium has the world's leading specific strength, can withstand an extreme temperature range of -253℃ to 600℃, and has excellent fatigue resistance and corrosion resistance. In applications, TC4/TC11 titanium alloys can be made into titanium alloy fan blades for high-bypass ratio engines with a profile contour accuracy of ±0.08mm; they are also used for fuselage frames, landing gear components, and spacecraft fuel tanks. The TC4/TC11 titanium alloy forgings, titanium plates, titanium tubes, and precision titanium processed parts of Baoji Yunjie Metal have a room-temperature tensile strength of ≥950MPa and a density of only 57% that of steel, which can achieve a lightweight weight reduction of over 30% for equipment.
