The precision drawing equipment is equipped with a real-time online diameter measuring system. The tolerance for fine wires is controlled within +/-0.005mm, and the thick wires are controlled according to international standard percentages. Stress relief and grain refinement during multi-pass processing ensure that the material has excellent plasticity and uniform structure.

(2) What Should You Know About Heat Treatment and Surface Treatment Process?

Annealing treatment is a key process for regulating the performance of nickel wire. By controlling the heating temperature (usually 600-900℃) and holding time, work hardening can be eliminated and the material plasticity can be restored. Atmosphere protected annealing avoids surface oxidation and maintains material purity. Surface treatment includes four types: glossy surface, semi-glossy surface, pickled surface, and polished surface. The bright surface is suitable for decoration and precision electronics, the pickled surface is suitable for welding to remove oxide scale, and the polished surface is used for medical devices with high cleanliness requirements.
