Refractory Metal AlBeMet AM162 vs I-220H

Refractory Metal · grade comparison

Refractory Metal AlBeMet AM162 and I-220H are both refractory metal grades. I-220H is the stronger of the two: yield strength 345 MPa (50 ksi) against 193 MPa (28 ksi) for AlBeMet AM162, about 79% more; tensile strength follows at 462 MPa (67 ksi) vs 262 MPa (38 ksi). In exchange, AlBeMet AM162 is the more ductile: elongation 2.5% versus 2% for I-220H, and I-220H is harder (180 HB vs 100 HB). I-220H is lighter (1.85 g/cm³ vs 2.1 g/cm³ for AlBeMet AM162) and I-220H is stiffer (303 GPa vs 193 GPa). On the shop floor, AlBeMet AM162 machines more easily (fair vs poor).

AlBeMet AM162Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

I-220HChoose it when strength drives the design, or when weight is the constraint.

AlBeMet AM162 vs I-220H — frequently asked

Is I-220H stronger than AlBeMet AM162?

Yes. I-220H has a typical yield strength of 345 MPa (50 ksi) against 193 MPa (28 ksi) for AlBeMet AM162 — about 79% more. Tensile strength is 462 MPa (67 ksi) vs 262 MPa (38 ksi).

Which is cheaper, AlBeMet AM162 or I-220H?

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-220H?

AlBeMet AM162. Its machinability rates fair (45/100) against poor (25/100) for I-220H; for welding the order is AlBeMet AM162 first (poor, 25/100) then I-220H (poor, 20/100).
