Refractory Metal Mo (Grade 360) vs Mo-La
Refractory Metal · grade comparison
Refractory Metal Mo (Grade 360) and Mo-La are both refractory metal grades. Mo (Grade 360) is the stronger of the two: tensile strength 760 MPa (110 ksi) against 700 MPa (102 ksi) for Mo-La, about 9% more. Mo (Grade 360) is the more ductile: elongation 15% versus 8% for Mo-La. Mo-La runs hotter in service (1,700°C vs 1,100°C continuous) and Mo (Grade 360) conducts heat better (138 W/m·K vs 120 W/m·K). On the shop floor, Mo (Grade 360) sits in a lower cost tier (high, $$$$) than Mo-La (specialty, $$$$$).
Mo (Grade 360)Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
Mo-LaChoose it when the part sees heat.
Mo (Grade 360) vs Mo-La: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all refractory metal 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.
