Refractory Metal Mo1/Mo2 SINT vs Mo1/Mo2-SR
Refractory Metal · Mo1/Mo2 temper comparison
Mo1/Mo2 SINT and Mo1/Mo2-SR are two conditions of the same refractory metal grade, Mo1/Mo2: SINT (sintered) versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. Mo1/Mo2-SR is the stronger of the two: yield strength 580 MPa (84.1 ksi) against 250 MPa (36.3 ksi) for Mo1/Mo2 SINT, about 132% more; tensile strength follows at 700 MPa (102 ksi) vs 300 MPa (43.5 ksi). Mo1/Mo2-SR is the more ductile: elongation 18% versus 1% for Mo1/Mo2 SINT, and Mo1/Mo2-SR is harder (225 HB vs 143 HB). Mo1/Mo2 SINT is lighter (9.8 g/cm³ vs 10.22 g/cm³ for Mo1/Mo2-SR) and Mo1/Mo2-SR is stiffer (320 GPa vs 275 GPa). On the shop floor, Mo1/Mo2 SINT machines more easily (50 vs 40 out of 100).
Mo1/Mo2 SINTChoose it when weight is the constraint, or when the part is machined in volume.
Mo1/Mo2-SRChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
Mo1/Mo2 SINT vs Mo1/Mo2-SR: 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.

Mo1/Mo2 SINT vs Mo1/Mo2-SR — frequently asked
Is Mo1/Mo2-SR stronger than Mo1/Mo2 SINT?
Yes. Mo1/Mo2-SR has a typical yield strength of 580 MPa (84.1 ksi) against 250 MPa (36.3 ksi) for Mo1/Mo2 SINT — about 132% more. Tensile strength is 700 MPa (102 ksi) vs 300 MPa (43.5 ksi).
Which condition does FabDigit quote by default, SINT or SR?
SR is the default Mo1/Mo2 condition in the FabDigit quote flow. The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, Mo1/Mo2 SINT or Mo1/Mo2-SR?
Mo1/Mo2 SINT, by a small margin. Both rate fair for machinability — 50/100 against 40/100 for Mo1/Mo2-SR; for welding the order is Mo1/Mo2-SR first (poor, 20/100) then Mo1/Mo2 SINT (poor, 15/100).
