Nickel Alloy CZ-100 vs N30C

Nickel Alloy · grade comparison

Nickel Alloy CZ-100 and N30C are both nickel alloy grades. N30C is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 160 MPa (23.2 ksi) for CZ-100, about 88% more; tensile strength follows at 550 MPa (79.8 ksi) vs 380 MPa (55.1 ksi). In exchange, CZ-100 is the more ductile: elongation 25% versus 15% for N30C, and N30C is harder (195 HB vs 110 HB). N30C is stiffer (210 GPa vs 180 GPa) and N30C runs hotter in service (760°C vs 480°C continuous). On the shop floor, CZ-100 machines more easily (fair vs poor).

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

N30CChoose it when strength drives the design, or when the part sees heat.

CZ-100 vs N30C — frequently asked

Is N30C stronger than CZ-100?

Yes. N30C has a typical yield strength of 300 MPa (43.5 ksi) against 160 MPa (23.2 ksi) for CZ-100 — about 88% more. Tensile strength is 550 MPa (79.8 ksi) vs 380 MPa (55.1 ksi).

Which is cheaper, CZ-100 or N30C?

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 N30C?

CZ-100. Its machinability rates fair (35/100) against poor (20/100) for N30C; for welding the order is N30C first (good, 65/100) then CZ-100 (good, 60/100).
