Round wire is cold drawn through a circular die and available in short lengths or complete spools. Since wire is drawn rather than rolled, it is highly flexible and can be easily wound into complex shapes.  Heat treatments can be used to set a permanent shape and to modify the thermal and mechanical properties.  As a raw material, we supply wire with black oxide and polished surface finishes. However, we have numerous other surface finishes available upon request for your application.

Price listed below is for 5 feet (1.5meter) of Nitinol wires. If multiple packs are purchased and continuous length is desired, please leave a note in the comment box during check out or contact us.
