Titanium B817 Type II vs CP-Ti Powder (GB/T 30265)
Titanium · grade comparison
Titanium B817 Type II and CP-Ti Powder (GB/T 30265) are both titanium grades. B817 Type II is the stronger of the two: yield strength 855 MPa (124 ksi) against 350 MPa (50.8 ksi) for CP-Ti Powder (GB/T 30265), about 144% more; tensile strength follows at 930 MPa (135 ksi) vs 450 MPa (65.3 ksi). B817 Type II is harder — 330 HB against 160 HB for CP-Ti Powder (GB/T 30265) — which matters for wear surfaces and threads. B817 Type II is stiffer (113 GPa vs 105 GPa) and B817 Type II runs hotter in service (350°C vs 300°C continuous). On the shop floor, CP-Ti Powder (GB/T 30265) machines more easily (fair vs poor), CP-Ti Powder (GB/T 30265) welds better (very good vs good), and CP-Ti Powder (GB/T 30265) forms better (good vs poor).
B817 Type IIChoose it when strength drives the design, or when surface hardness matters.
CP-Ti Powder (GB/T 30265)Choose it when the part is machined in volume, or when it will be welded.
B817 Type II vs CP-Ti Powder (GB/T 30265): propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all titanium grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

B817 Type II vs CP-Ti Powder (GB/T 30265) — frequently asked
Is B817 Type II stronger than CP-Ti Powder (GB/T 30265)?
Yes. B817 Type II has a typical yield strength of 855 MPa (124 ksi) against 350 MPa (50.8 ksi) for CP-Ti Powder (GB/T 30265) — about 144% more. Tensile strength is 930 MPa (135 ksi) vs 450 MPa (65.3 ksi).
Which is cheaper, B817 Type II or CP-Ti Powder (GB/T 30265)?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, B817 Type II or CP-Ti Powder (GB/T 30265)?
CP-Ti Powder (GB/T 30265). Its machinability rates fair (35/100) against poor (20/100) for B817 Type II; for welding the order is CP-Ti Powder (GB/T 30265) first (very good, 80/100) then B817 Type II (good, 60/100).
