Titanium Grade 1 vs Ti-6Al-5Zr-0.5Mo
Titanium · grade comparison
Titanium Grade 1 and Ti-6Al-5Zr-0.5Mo are both titanium grades. Ti-6Al-5Zr-0.5Mo is the stronger of the two: yield strength 900 MPa (131 ksi) against 220 MPa (31.9 ksi) for Grade 1, about 4.1 times as much; tensile strength follows at 1,030 MPa (149 ksi) vs 300 MPa (43.5 ksi). In exchange, Grade 1 is the more ductile: elongation 30% versus 10% for Ti-6Al-5Zr-0.5Mo, and Ti-6Al-5Zr-0.5Mo is harder (310 HB vs 120 HB). Ti-6Al-5Zr-0.5Mo is stiffer (120 GPa vs 103 GPa) and Ti-6Al-5Zr-0.5Mo runs hotter in service (520°C vs 300°C continuous). On the shop floor, Grade 1 machines more easily (fair vs poor), Grade 1 welds better (excellent vs good), and Ti-6Al-5Zr-0.5Mo sits in a lower cost tier (high, $$$$) than Grade 1 (specialty, $$$$$).
Grade 1Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
Ti-6Al-5Zr-0.5MoChoose it when strength drives the design, or when the part sees heat.
Grade 1 vs Ti-6Al-5Zr-0.5Mo: 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.
