NiTi Actuating Wire
Nitinol SMA Actuating Wire, whose physical function resembles biological muscle, will contract when it is activated.
◎By heating it electrically, the wire will be activated when the temperature is above its transition temperature.
◎When the material cools, it can be stretched back to its original length for subsequent contractions.
◎The small size, light weight, ease of use and silent operation
◎Diameter Range: φ0.025~φ0.5mm
◎Surface State Options:
·Oxide Surface
◎Dimensional tolerances:according to the finished diameter range
