Nickel Titanium (Nitinol or NiTi) belongs to a unique class of shape memory alloys. Its extraordinary properties stem from a thermoelastic martensitic phase transformation within the material. Standard Nitinol alloys typically consist of 55%-56% Nickel and 44%-45% Titanium. Minor adjustments in composition can significantly influence the material's performance characteristics.
Two Primary Categories of Nitinol:
Material Availability: Our alloys include Pure Nickel, NiCr Alloy, Fe-Cr-Al Alloy, and Copper Nickel Alloy. These are available in wire, coil, ribbon, strip, and foil forms.
