Black iron wire

Specifications: Wire diameter 0.81-6.4mm
Process: the hot metal billet is rolled into wire rod of 6.5mm thick steel strip is then put into the drawing apparatus pulled into a different diameter line, and gradually narrow the pore size of the drawing tray, cooled, annealed, coated made from a variety of different specifications of wire and other processes. It contains the ingredients are: iron, cobalt, nickel, copper, carbon, zinc, as well as other elements.
Features: black wire has good elasticity and flexibility, and can control the hardness of the annealing process, made ​​of high quality iron wire, mainly used in the construction industry as binding wire and binding wire. Wire No. 5 # -38 # (wire by 0.17-4.5mm)
Purposes: mainly used in construction, mining, chemical, welded mesh, welded hanger reprocessing. Annealed wire softened increase pliability, doing construction tie wire, steel banding effect more.
