Tension annealing is a popular method to straighten superfine wire. This paper investigates the effect on wire straightness of heating temperature, tension, and initial radius of curvature during annealing. Results indicate in both phosphor bronze superfine wire and tungsten superfine wire that as the heating temperature and tension increases, the wire straightness improves. It is also found that straightness improves as the initial curvature radius increases.
