Steel Wires are widely used not only in manufacturing but also in everyday life. Steel wire for general purpose are made of mild steel with a diameter of 0.5-12.0 mm. Production is carried out using a method that is associated with repeated cold drawing.
Black iron or annealed wire is softer, more flexible, uniform in softness and consistent in color. Mainly used in construction, mining, chemical and so on.
Advantages of iron wire annealing: After wire annealing, the wire elongation will increase. The product is softer and increases the applicable range of wire. The black iron wire can be electro galvanized, hot-dip galvanizing, electroplating copper, etc.
