Linear Elastic Nitinol

When Linear Elastic Nitinol is subjected to strain, the stress increase is nearly proportional. This linear performance sets it apart from standard superelastic or shape memory Nitinol, which would deform more easily upon reaching its plateau stress. This product features a stiffer wire that offers greater pushability, primarily required by guidewire applications, along with greater strength without sacrificing 1:1 torque transmission. Linear Elastic Nitinol will recover up to 4% strain, which is not dependent on a temperature induced phase change.
