Refractory Metal AlBeMet AM162 vs I-70-H

Refractory Metal · grade comparison

Refractory Metal AlBeMet AM162 and I-70-H are both refractory metal grades. I-70-H is the stronger of the two: yield strength 205 MPa (29.7 ksi) against 193 MPa (28 ksi) for AlBeMet AM162, about 6% more; tensile strength follows at 310 MPa (45 ksi) vs 262 MPa (38 ksi). I-70-H is the more ductile: elongation 4.5% versus 2.5% for AlBeMet AM162, and I-70-H is harder (120 HB vs 100 HB). I-70-H is lighter (1.85 g/cm³ vs 2.1 g/cm³ for AlBeMet AM162) and I-70-H is stiffer (303 GPa vs 193 GPa). On the shop floor, AlBeMet AM162 machines more easily (45 vs 35 out of 100).

AlBeMet AM162 vs I-70-H — frequently asked

Is I-70-H stronger than AlBeMet AM162?

Yes. I-70-H has a typical yield strength of 205 MPa (29.7 ksi) against 193 MPa (28 ksi) for AlBeMet AM162 — about 6% more. Tensile strength is 310 MPa (45 ksi) vs 262 MPa (38 ksi).

Which is cheaper, AlBeMet AM162 or I-70-H?

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 I-70-H?

AlBeMet AM162, by a small margin. Both rate fair for machinability — 45/100 against 35/100 for I-70-H; for welding the order is AlBeMet AM162 first (poor, 25/100) then I-70-H (poor, 20/100).
