Black annealed wire

Black annealed wire is made of low-carbon steel cold drawn, heated, constant temperature, insulation and other processing into a soft wire products. The use of wire is different, the composition is different, it contains the ingredients are: iron, cobalt, nickel, copper, carbon, zinc, and other elements. The hot metal blanks rolled into 6.5mm thick steel bar is the wire rod, and then into the drawing device into a different diameter of the line, and gradually reduce the diameter of the drawing plate, cooling, annealing, coating and other processing Craft made of a variety of different specifications of the wire.

Black iron 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 is increased. 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., it is widely used in wire mesh production. Post plating, first plating, etc
