- High fracture toughness (K₁C ≥ 50 MPa·m¹/²)

- Excellent fatigue resistance

- Fine tempered martensite matrix with controlled impurity elements and grain boundary segregation.

- Applications: Aircraft landing gear struts, main load-bearing joints, seat rails, high-strength fasteners.

Superalloy bar: Operating continuously in extreme thermal-mechanical environments

- Exceptional high-temperature strength and creep resistance

- Outstanding oxidation/thermal corrosion resistance

- Excellent thermomechanical fatigue performance

- Stability in the quantity, size, morphology, and distribution of γ' phase (Ni₃(Al, Ti)).

- Applications: Engine turbine disks, turbine shafts, compressor disks, key fasteners for combustion chambers.

Titanium alloy bar: Achieving a combination of high strength, light weight, and corrosion resistance

- Top-tier specific strength

- Excellent fatigue resistance and crack propagation resistance

- Superior corrosion resistance

- The ratio, morphology, and texture of α+β phases. Purity (control of interstitial elements O and N) is crucial.
