Nickel Alloy CZ-100 vs K417G

Nickel Alloy · grade comparison

Nickel Alloy CZ-100 and K417G are both nickel alloy grades. K417G is the stronger of the two: yield strength 800 MPa (116 ksi) against 160 MPa (23.2 ksi) for CZ-100, about 5.0 times as much; tensile strength follows at 920 MPa (133 ksi) vs 380 MPa (55.1 ksi). In exchange, CZ-100 is the more ductile: elongation 25% versus 6% for K417G, and K417G is harder (345 HB vs 110 HB). K417G is lighter (7.8 g/cm³ vs 8.85 g/cm³ for CZ-100) and K417G is stiffer (205 GPa vs 180 GPa). On the shop floor, CZ-100 machines more easily (fair vs not recommended) and CZ-100 welds better (good vs not recommended).

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

K417GChoose it when strength drives the design, or when weight is the constraint.

CZ-100 vs K417G — frequently asked

Is K417G stronger than CZ-100?

Yes. K417G has a typical yield strength of 800 MPa (116 ksi) against 160 MPa (23.2 ksi) for CZ-100 — about 5.0 times as much. Tensile strength is 920 MPa (133 ksi) vs 380 MPa (55.1 ksi).

Which is cheaper, CZ-100 or K417G?

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 K417G?

CZ-100. Its machinability rates fair (35/100) against not recommended (10/100) for K417G; for welding the order is CZ-100 first (good, 60/100) then K417G (not recommended, 10/100).
