Titanium CP-Ti Grade 2 (AM Powder) vs Ti-6Al-4V (Grade 5) AM Powder
Titanium · grade comparison
Titanium CP-Ti Grade 2 (AM Powder) and Ti-6Al-4V (Grade 5) AM Powder are both titanium grades. Ti-6Al-4V (Grade 5) AM Powder is the stronger of the two: yield strength 1,020 MPa (148 ksi) against 530 MPa (76.9 ksi) for CP-Ti Grade 2 (AM Powder), about 92% more; tensile strength follows at 1,120 MPa (162 ksi) vs 640 MPa (92.8 ksi). In exchange, CP-Ti Grade 2 (AM Powder) is the more ductile: elongation 18% versus 12% for Ti-6Al-4V (Grade 5) AM Powder, and Ti-6Al-4V (Grade 5) AM Powder is harder (340 HB vs 205 HB). Ti-6Al-4V (Grade 5) AM Powder is stiffer (113 GPa vs 105 GPa) and Ti-6Al-4V (Grade 5) AM Powder runs hotter in service (350°C vs 300°C continuous). On the shop floor, CP-Ti Grade 2 (AM Powder) machines more easily (fair vs poor) and CP-Ti Grade 2 (AM Powder) welds better (excellent vs good).
CP-Ti Grade 2 (AM Powder)Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
Ti-6Al-4V (Grade 5) AM PowderChoose it when strength drives the design, or when the part sees heat.
CP-Ti Grade 2 (AM Powder) vs Ti-6Al-4V (Grade 5) AM Powder: 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.

CP-Ti Grade 2 (AM Powder) vs Ti-6Al-4V (Grade 5) AM Powder — frequently asked
Is Ti-6Al-4V (Grade 5) AM Powder stronger than CP-Ti Grade 2 (AM Powder)?
Yes. Ti-6Al-4V (Grade 5) AM Powder has a typical yield strength of 1,020 MPa (148 ksi) against 530 MPa (76.9 ksi) for CP-Ti Grade 2 (AM Powder) — about 92% more. Tensile strength is 1,120 MPa (162 ksi) vs 640 MPa (92.8 ksi).
Which is cheaper, CP-Ti Grade 2 (AM Powder) or Ti-6Al-4V (Grade 5) AM Powder?
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, CP-Ti Grade 2 (AM Powder) or Ti-6Al-4V (Grade 5) AM Powder?
CP-Ti Grade 2 (AM Powder). Its machinability rates fair (38/100) against poor (20/100) for Ti-6Al-4V (Grade 5) AM Powder; for welding the order is CP-Ti Grade 2 (AM Powder) first (excellent, 88/100) then Ti-6Al-4V (Grade 5) AM Powder (good, 60/100).
