Working with CP-Ti Powder for MIM MIM-VA
Is CP-Ti Powder for MIM easy to machine?
Sintered CP-Ti machines like wrought Grade 2 — low speed, high feed, sharp uncoated carbide and flood coolant; avoid dwelling (work-hardening and fire risk from fine chips/powder).
Can CP-Ti Powder for MIM be welded?
GTAW/laser/resistance welding under full argon shielding works well on HIPed parts; as-sintered porosity can outgas and cause weld porosity, so pre-bake and use HIPed material for critical joints.
Can CP-Ti Powder for MIM be formed, bent or molded?
Feedstock at 50–62 vol % solids, mould 160–190 °C tool 30–50 °C; solvent/catalytic + thermal debinding then vacuum (<10⁻² Pa) or high-purity Ar sintering at 1250–1350 °C with 13–18 % linear shrinkage — never sinter in nitrogen or on graphite without a Y₂O₃ barrier.
What surface finishes work on CP-Ti Powder for MIM?
Bead blasting, tumbling, chemical etch (HNO₃/HF) for oxide removal, then Type II colour or Type III anodising; passivation per ASTM F86 for medical parts, PVD/DLC and plasma nitriding also used for wear.

Is CP-Ti Powder for MIM MIM-VA easy to machine?
Not especially — machinability is rated poor (28/100, better than 59% of titanium grades). Sintered CP-Ti machines like wrought Grade 2 — low speed, high feed, sharp uncoated carbide and flood coolant; avoid dwelling (work-hardening and fire risk from fine chips/powder).
Can CP-Ti Powder for MIM MIM-VA be welded?
Yes — weldability is rated good (60/100). GTAW/laser/resistance welding under full argon shielding works well on HIPed parts; as-sintered porosity can outgas and cause weld porosity, so pre-bake and use HIPed material for critical joints.
What surface finishes work on CP-Ti Powder for MIM MIM-VA?

What is the maximum service temperature of CP-Ti Powder for MIM MIM-VA?
CP-Ti Powder for MIM MIM-VA is rated for continuous use to about 300°C (572 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between CP-Ti Powder for MIM MIM-AS and CP-Ti Powder for MIM-GR4?
MIM-AS is the default condition — default supply condition for MIM CP-Ti parts: 96–99 % dense, properties comparable to annealed wrought Grade 2 except reduced fatigue and ductility. GR4: pick when the highest unalloyed-Ti strength is needed (dental/surgical instruments); ductility and impact toughness drop markedly. Yield strength is 380 MPa in MIM-AS versus 520 MPa in GR4.
