Titanium Casting

Introduction of Titanium Casting Process

The Titanium casting process includes graphite mold casting and investment casting. Graphite mold casting is the main molding process for producing civilian titanium castings.

Investment casting is the main process for producing aviation titanium alloy castings with high precision, complex shape, smooth surface, and dense interior.

The most widely used titanium material is Ti-6A1-4V alloy. It has good casting performance and stable structural properties. Compared with wrought alloys of the same composition, the strength of cast titanium alloys is basically the same, but their plasticity and fatigue properties are about 40%~50% lower, while the Fracture toughness is slightly better.

Titanium material castings generally adopt stabilization annealing treatment, and the solid solution treatment and hydrogenation treatment in research can refine grains, improve microstructure, and improve alloy fatigue performance to the level of forgings. Hot isostatic pressing is a common treatment method for high-quality titanium castings.

Application of Titanium Castings

Titanium material castings are mainly used in the aerospace industry. Important components used include: engine compressor casing, intermediate casing, blades, hollow guide, inner ring, supercharger impeller, bearing housing and support, aircraft bracket, umbrella compartment, ear piece, short beam, flap slide rail, brake housing; Missile control cabin, tail wing, rocket rear head, common bottom, etc; Supports, scanner frames, mirror tubes, etc. for artificial satellites. Widely used in the manufacturing of corrosion-resistant pump bodies, valves, and impellers in civil industry; Spiral propellers for ships; The shell, bracket, and cylinder of precision machinery; Medical artificial joints, prosthetic limb components; Golf head, harness, bicycle parts, etc. for sports equipment.
