Part Name: Impeller

Core Performance Advantages

Extreme lightweighting: With a density of only 3.7–3.9 g/cm³—about half that of nickel-based alloys (7.9–9.5 g/cm³)—a single aircraft engine can achieve weight savings of 90–136 kg, significantly reducing rotational inertia and improving the thrust-to-weight ratio.
High-temperature strength and toughness: With a long-term service temperature range of 700–850°C, it exhibits a yield strength of ≥340 MPa at 850°C, outstanding creep resistance and fatigue performance, and a sustained life exceeding 130 hours—far surpassing that of conventional titanium alloys.
High specific strength and high specific stiffness: Leading in both specific strength and specific stiffness, with an elastic modulus of approximately 160–175 GPa, it combines the toughness of metals with the heat resistance of ceramics, making it resistant to deformation and fracture even under high-speed operation.
Long-lasting corrosion resistance: Outstanding high-temperature oxidation and sulfidation resistance, with an oxidation weight gain of ≤0.9 mg/cm² at 850°C, making it suitable for harsh environments such as high‑temperature combustion gases and humid conditions, thereby extending equipment service life.
Energy conservation, cost reduction, and efficiency gains: In aviation applications, fuel consumption can be reduced by 1.5%–15%, and nitrogen oxide emissions can be cut by more than 30%; in the industrial sector, maintenance frequency is lowered, leading to a significant overall cost optimization.

Mainstream Materials and Processes

Classic alloy grades: Ti-48Al-2Cr-2Nb (GE 48-2-2) and Ti-(43–44)Al-4Nb-1Mo-0.1B (TNM), tailored to meet varying temperature and strength requirements.
Precision Manufacturing: Employing vacuum induction melting, hot isostatic pressing, and isothermal forging, combined with precision casting processes, the material exhibits a uniform, fine-grained microstructure, high near-net-shape dimensional accuracy, and excellent batch-to-batch consistency.

Core application areas

Aerospace engines: low-pressure turbine blades (e.g., GEnx, PW1100G) and high-pressure compressor blades, compatible with mainstream aircraft such as the Boeing 787 and the Airbus A320neo.
Heavy-duty gas turbines: For power generation and industrial‑drive applications, the high‑temperature‑stage blades and guide vanes are designed to withstand prolonged continuous operation at elevated temperatures.
New Energy and High-End Equipment: Heavy-duty turbocharger impellers, high-speed compressor blades, and marine propulsion turbine components, tailored to meet demands for high efficiency and energy savings.
