Slender or thin diameter wires which contract like muscles when electrically driven so it’s become interesting point to know the effect unique parameters as light weight value of SMA, load or distance gain with instant time response for its actuation. In this proposed work the two springs having different number of turns and different diameter as 0.1 and 0.2 mm are prepared with the help of fixture-cum- spring tool then heat treatment was provided in the furnace at 530°C for 45 min and then cooled for 16 hours just by switch-off the furnace and placed in contact of air upto 6 hr to opening of the gate of furnace. The parameters include the average wire temperature, average strain capacity, scale-load capability response and wire-current and voltage during working.
