Key Features & Advantages

Elite High-Temperature Endurance: Retains high tensile strengths (≥1000 MPa) and resists creep under continuous 650°C loading limits.
Excellent Rheology Behavior: Spherical particle morphology (≥0.9) and high flow speed (≤18 s/50g) prevent layout layer voids.
Premium Post-Aging Response: Niobium modifications deliver profound precipitation responses to heat treatments for critical stress resistance.

APPLICATION SCOPE: Manufacturing aero-engine discs, rings, blades, shafts, fasteners, elastic elements, high-load sheet metal structures, and casings.

PACKAGING: Sealed in heavy industrial protective vials blanked with high-purity argon gas to halt surface oxidation.

IMPORTANT NOTICE: This product is highly sensitive to ambient exposure. Keep containers tightly sealed or handle exclusively within an anhydrous inert gas environment to prevent phase contamination or degradation before thermal validation.
