What is CP-Ti Powder (GB/T 30265)?

CP-Ti Powder (GB/T 30265) is unalloyed titanium powder covered by GB/T 30265 and roughly equivalent to ASTM B817 Type I powder, with a consolidated density of 4.51 g/cm³. It is supplied as irregular HDH powder for press-and-sinter work and as spherical gas-atomised, PREP or plasma-spheroidised grades for HIP, MIM and laser or electron-beam additive manufacturing. Engineers select it where corrosion resistance, ductility and biocompatibility matter more than strength. Strength is well below Ti-6Al-4V powder, and residual porosity in as-sintered parts limits welding and anodising. CP-Ti Powder (GB/T 30265) has a density of 4.51 g/cm³ (0.163 lb/in³), heavier than 57% of titanium grades. It melts at 1,660°C (3,020 °F). CP-Ti Powder (GB/T 30265) has a yield strength of 350 MPa (50.8 ksi) and a tensile strength of 450 MPa (65.3 ksi) — weaker than 79% of titanium grades. Elongation at break is 12% and the elastic modulus is 105 GPa (15.2 Msi).

Working with CP-Ti Powder (GB/T 30265)

Is CP-Ti Powder (GB/T 30265) easy to machine?

Machine consolidated PM parts with sharp uncoated carbide, low speed (30–60 m/min), heavy rigid setup and flood coolant; titanium chips and grinding dust ignite easily.

Can CP-Ti Powder (GB/T 30265) be welded?

GTAW/EBW/LBW with full argon or vacuum shielding gives sound joints, but porous as-sintered parts outgas — weld only HIP'd or >99 % dense material.

Can CP-Ti Powder (GB/T 30265) be formed, bent or molded?

Cold-press at 400–700 MPa with lubricated die (HDH powder), vacuum sinter 1200–1300 °C; spherical GA/PREP powder is used for HIP, MIM and laser/electron-beam AM under inert atmosphere.
