Abstract
A superelastic strand used for windings in a golf ball or as strings for a racquet of the type used for racquet sports. The strand is made with at least one fiber of a superelastic material which may be wound into a cable incorporating other fibers of polymeric or superelastic materials. The superelastic material used in the strand can be a nickel-titanium alloy which is heat treated to provide superelastic qualities.
