The strands in this wire have better fatigue resistance under repeated flexing than the copper strands in standard continuous-flex wire, so it will last longer. Often used in low-current signaling in automated applications such as robotics, it withstands continuous motion without degrading data or signal transmission.

Metallic tinsel wire has thin strands of metal wrapped around a fiber core to provide better flexibility and longer service life than carbon fiber wire. Wire with a Kevlar plastic core has 7 strands.
