Working with CP-Ti Grade 2 (AM Powder) BJT-SINT
Is CP-Ti Grade 2 (AM Powder) easy to machine?
Use sharp uncoated-carbide or PVD tools, low surface speed (30–60 m/min), heavy positive rake, high-pressure flood coolant; never dwell — Ti work-hardens, galls and fine chips/dust are a fire hazard.
Can CP-Ti Grade 2 (AM Powder) be welded?
Excellent GTAW/EBW/LBW weldability provided the weld pool and hot HAZ are fully shielded with argon/helium trailing and backing gas; welds stay ductile, discoloration beyond straw indicates contamination.
Can CP-Ti Grade 2 (AM Powder) be formed, bent or molded?
Parts are net-shape from the printer; recoater/scan strategy plus 600 °C stress relief before plate removal controls warp, and powder must be sieved and handled under low-moisture inert conditions to limit O/H pickup.
What surface finishes work on CP-Ti Grade 2 (AM Powder)?
Support removal, blasting, tumbling, chemical etch or abrasive-flow polishing to cut as-built Ra 8–20 µm; anodizes to bright interference colors and passivates naturally per ASTM F86 for medical use.

CP-Ti Grade 2 (AM Powder) BJT-SINT — frequently asked
What is CP-Ti Grade 2 (AM Powder) BJT-SINT used for?
CP-Ti Grade 2 (AM Powder) BJT-SINT is typically used for dental frameworks, chemical process components, marine hardware, heat exchanger parts and medical device housings. In short: most ductile AM titanium; unalloyed corrosion-resistant powder; medical and chemical duty.
What is the yield strength of CP-Ti Grade 2 (AM Powder) BJT-SINT?
CP-Ti Grade 2 (AM Powder) BJT-SINT has a typical yield strength of 350 MPa (50.8 ksi) and a tensile strength of 460 MPa (66.7 ksi) — weaker than 79% of titanium grades. Strength varies by condition: see the 2 listed tempers.
Is CP-Ti Grade 2 (AM Powder) BJT-SINT easy to machine?
Not especially — machinability is rated fair (40/100, better than 93% of titanium grades). Use sharp uncoated-carbide or PVD tools, low surface speed (30–60 m/min), heavy positive rake, high-pressure flood coolant; never dwell — Ti work-hardens, galls and fine chips/dust are a fire hazard.
Can CP-Ti Grade 2 (AM Powder) BJT-SINT be welded?
Yes — weldability is rated very good (70/100). Excellent GTAW/EBW/LBW weldability provided the weld pool and hot HAZ are fully shielded with argon/helium trailing and backing gas; welds stay ductile, discoloration beyond straw indicates contamination.
What surface finishes work on CP-Ti Grade 2 (AM Powder) BJT-SINT?
