Refractory Metal AlBeMet AM200 vs S-65
Refractory Metal · grade comparison
Refractory Metal AlBeMet AM200 and S-65 are both refractory metal grades. S-65 is the stronger of the two: yield strength 230 MPa (33.4 ksi) against 200 MPa (29 ksi) for AlBeMet AM200, about 15% more; tensile strength follows at 350 MPa (50.8 ksi) vs 275 MPa (39.9 ksi). S-65 is the more ductile: elongation 4.5% versus 3% for AlBeMet AM200, and S-65 is harder (115 HB vs 100 HB). S-65 is lighter (1.85 g/cm³ vs 2.13 g/cm³ for AlBeMet AM200) and S-65 is stiffer (303 GPa vs 188 GPa). On the shop floor, S-65 machines more easily (45 vs 35 out of 100).
S-65Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
AlBeMet AM200 vs S-65: 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.

AlBeMet AM200 vs S-65 — frequently asked
Is S-65 stronger than AlBeMet AM200?
Yes. S-65 has a typical yield strength of 230 MPa (33.4 ksi) against 200 MPa (29 ksi) for AlBeMet AM200 — about 15% more. Tensile strength is 350 MPa (50.8 ksi) vs 275 MPa (39.9 ksi).
Which is cheaper, AlBeMet AM200 or S-65?
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, AlBeMet AM200 or S-65?
S-65, by a small margin. Both rate fair for machinability — 45/100 against 35/100 for AlBeMet AM200.
