Refractory Metal AlBeMet AM162 vs O-30H

Refractory Metal · grade comparison

Refractory Metal AlBeMet AM162 and O-30H are both refractory metal grades. O-30H is the stronger of the two: yield strength 207 MPa (30 ksi) against 193 MPa (28 ksi) for AlBeMet AM162, about 7% more; tensile strength follows at 324 MPa (47 ksi) vs 262 MPa (38 ksi). O-30H is the more ductile: elongation 3% versus 2.5% for AlBeMet AM162, and O-30H is harder (140 HB vs 100 HB). O-30H is lighter (1.85 g/cm³ vs 2.1 g/cm³ for AlBeMet AM162) and O-30H is stiffer (303 GPa vs 193 GPa). On the shop floor, AlBeMet AM162 machines more easily (45 vs 35 out of 100) and AlBeMet AM162 welds better (25 vs 15 out of 100).

AlBeMet AM162 vs O-30H — frequently asked

Is O-30H stronger than AlBeMet AM162?

Yes. O-30H has a typical yield strength of 207 MPa (30 ksi) against 193 MPa (28 ksi) for AlBeMet AM162 — about 7% more. Tensile strength is 324 MPa (47 ksi) vs 262 MPa (38 ksi).

Which is cheaper, AlBeMet AM162 or O-30H?

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 AM162 or O-30H?

AlBeMet AM162, by a small margin. Both rate fair for machinability — 45/100 against 35/100 for O-30H; for welding the order is AlBeMet AM162 first (poor, 25/100) then O-30H (poor, 15/100).
