Nickel Alloy CZ-100 vs M30H

Nickel Alloy · grade comparison

Nickel Alloy CZ-100 and M30H are both nickel alloy grades. M30H is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 160 MPa (23.2 ksi) for CZ-100, about 3.3 times as much; tensile strength follows at 740 MPa (107 ksi) vs 380 MPa (55.1 ksi). In exchange, CZ-100 is the more ductile: elongation 25% versus 15% for M30H, and M30H is harder (290 HB vs 110 HB). M30H is lighter (8.3 g/cm³ vs 8.85 g/cm³ for CZ-100) and CZ-100 conducts heat better (50 W/m·K vs 17 W/m·K). On the shop floor, CZ-100 machines more easily (fair vs poor) and CZ-100 welds better (good vs poor).

CZ-100Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

M30HChoose it when strength drives the design, or when weight is the constraint.

CZ-100 vs M30H — frequently asked

Is M30H stronger than CZ-100?

Yes. M30H has a typical yield strength of 520 MPa (75.4 ksi) against 160 MPa (23.2 ksi) for CZ-100 — about 3.3 times as much. Tensile strength is 740 MPa (107 ksi) vs 380 MPa (55.1 ksi).

Which is cheaper, CZ-100 or M30H?

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, CZ-100 or M30H?

CZ-100. Its machinability rates fair (35/100) against poor (18/100) for M30H; for welding the order is CZ-100 first (good, 60/100) then M30H (poor, 25/100).
