Nickel 200 vs Nitinol

Nickel Alloy · grade comparison

Nickel 200 and Nitinol are both nickel alloy grades. Nitinol is the stronger of the two: yield strength 400 MPa (58 ksi) against 148 MPa (21.5 ksi) for Nickel 200, about 170% more; tensile strength follows at 950 MPa (138 ksi) vs 462 MPa (67 ksi). In exchange, Nickel 200 is the more ductile: elongation 47% versus 30% for Nitinol. Nitinol is lighter (6.45 g/cm³ vs 8.89 g/cm³ for Nickel 200) and Nickel 200 is stiffer (204 GPa vs 75 GPa). On the shop floor, Nickel 200 machines more easily (fair vs not recommended) and Nickel 200 welds better (excellent vs fair).

Nickel 200Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.

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

Nickel 200 vs Nitinol — frequently asked

Is Nitinol stronger than Nickel 200?

Yes. Nitinol has a typical yield strength of 400 MPa (58 ksi) against 148 MPa (21.5 ksi) for Nickel 200 — about 170% more. Tensile strength is 950 MPa (138 ksi) vs 462 MPa (67 ksi).

Which is cheaper, Nickel 200 or Nitinol?

Both sit in the same relative cost tier ($$$, premium); the part price will be decided by machining time, tolerance and quantity rather than by the material.

Which is easier to machine, Nickel 200 or Nitinol?

Nickel 200. Its machinability rates fair (35/100) against not recommended (12/100) for Nitinol; for welding the order is Nickel 200 first (excellent, 85/100) then Nitinol (fair, 35/100).
