Critical current of Nb{sub 3}Al is less sensitive to strain than Nb{sub 3}Sn. This characteristic makes a React-and-Wind method applicable in a large dimension coil. By applying the React-and-Wind method for Toloidal Field (TF) coil, technical difficulties in transfer of the conductor after reaction are eliminated and construction cost of magnet system can be reduced in comparison with a Wind-React-Insulate-Transfer method. Therefore, the Nb{sub 3}Al conductor has large potential as candidate for the TF conductor. The experiment of a 60 kA-12.5T Nb{sub 3}Al Insert is projected to demonstrate applicability of the React-and-Wind method with the Nb{sub 3}Al conductor. The React-and-Wind method will be employed in the winding and 0.4% bending strain will be applied to the conductor. The major characteristics of the Nb{sub 3}Al Insert are reported in this paper.
