Titanium SP-700 Annealed vs SP-700-CR
Titanium · SP-700 temper comparison
SP-700 Annealed and SP-700-CR are two conditions of the same titanium grade, SP-700: Annealed versus CR (cold rolled). The chemistry is identical, so every difference below comes from the condition. SP-700-CR is the stronger of the two: yield strength 1,010 MPa (146 ksi) against 860 MPa (125 ksi) for SP-700 Annealed, about 17% more; tensile strength follows at 1,080 MPa (157 ksi) vs 930 MPa (135 ksi). In exchange, SP-700 Annealed is the more ductile: elongation 17% versus 8% for SP-700-CR, and SP-700-CR is harder (340 HB vs 300 HB). SP-700 Annealed runs hotter in service (350°C vs 250°C continuous). On the shop floor, SP-700 Annealed welds better (65 vs 55 out of 100).
SP-700 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
SP-700-CRChoose it when strength drives the design.
SP-700 Annealed vs SP-700-CR: 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.
