Key Features & Advantages

Excellent Weldability & Structure: Formulated explicitly to match demanding high-temperature welded structures with minimum crack vulnerability.
Elite Powder Flow Profile: Strict spherical form factor (≥0.9) and excellent rheology flow (≤18 s/50g) prevent packing void formation.
High-Temperature Stress Endurance: Possesses robust room-temperature tensile baseline (≥1050 MPa) and maintains stable thresholds at 900°C.

APPLICATION SCOPE: Manufacturing critical high-temperature welded structures, including aero-engine combustion chambers, afterburners, and hot-section structural containment shells.

PACKAGING: Vacuum-sealed within high-durability laboratory containers overlaid with a dry argon gas envelope to prevent particle decay.

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.
