Advantages Of Annealed Wire

1. Black iron wire has strong elasticity and good flexibility, and its softness can be adjusted during annealing. It is made of steel wire and is mainly used for bundling and binding in the construction industry. The main thread sizes are 5 # -38 # (with a thread diameter of 0.17-4.5mm), which are softer, softer, and more uniform than ordinary black threads, with even chromaticity.
2. The production of steel wire generally adopts wire drawing process and galvanizing treatment. In 1976, new technologies such as electrolytic pickling, high-pressure cleaning, and card electric drying were first applied in China for continuous production of extension lines. The extension line process was changed from intermittent production to continuous production, weakening labor intensity and reducing metal consumption. At that time, domestic manufacturers were already able to produce steel wires such as wire ropes, spokes, umbrella ribs, springs, and bicycle saddle springs. In the 1980s, hot dip low-carbon steel wire, fan network wire, carbon structure wire, and bed surface wire were successively used for stapling.
