Forging-Grade Titanium Alloy Bar Stock

Product Specifications

Technical details and manufacturing context for Forging-Grade Titanium Alloy Bar Stock

Definition

Forging-grade titanium alloy bar stock is a semi-finished industrial material specifically engineered for subsequent metal forming operations including forging, pressing, and stamping. These bars are produced with controlled microstructure and mechanical properties to ensure optimal formability during hot or cold working processes. The material composition is precisely balanced to maintain strength while allowing plastic deformation without cracking or excessive wear on tooling. This product serves as the foundational raw material for producing high-performance forged components across aerospace, medical, and automotive industries. The bars are available in diameters ranging from 15 to 300 mm, with a diameter tolerance of ±0.05 mm, and standard mill lengths of 3000 to 6000 mm. The material is typically Ti-6Al-4V, with aluminum content between 5.5% and 6.75% and vanadium content between 3.5% and 4.5%. In the annealed condition, the minimum yield strength is 830 MPa, and the minimum elongation at fracture is 10%. The density is 4.43 g/cm³, and the weight per meter ranges from 0.5 to 10 kg depending on diameter. Surface roughness is maintained at a maximum Ra of 3.2 to ensure optimal forging contact. The recommended forging temperature range is 900–950°C. These parameters are referenced to ASTM B348 and ASTM B600 standards, which serve as procurement and verification references. It is essential to verify model-specific values and standards with the legal manufacturer or supplier before use.

Working Principle

The working principle of forging-grade titanium alloy bar stock is to provide uniform material properties and microstructure that allow controlled plastic deformation under compressive forces during forging operations. The alloy composition, particularly the balance of aluminum and vanadium, ensures that the material exhibits sufficient strength to withstand the forging process while maintaining ductility to avoid cracking. The controlled microstructure, achieved through precise manufacturing processes, enables consistent deformation behavior, reducing the risk of defects. The surface finish and dimensional tolerances are designed to facilitate proper die contact and material flow. During hot forging, the recommended temperature range of 900–950°C optimizes formability and reduces flow stress, allowing the material to be shaped into complex geometries without excessive tool wear. The material's response to compressive forces is predictable, enabling engineers to design forging processes with confidence in the final component's integrity.
