black annealed wire with vary diameter
Process: will the hot metal blank rolling into 6.5 mm thick steel bar is also the wire rod, and then put it into the drawing device inside draw different diameter line, and gradually reduce wire drawing dish aperture, cooling, annealing, coating and plating processing technology into all kinds of different specifications of the wire. It contains ingredients are: iron, cobalt, nickel, copper, carbon, zinc, and other elements.
black annealed wire with vary diameter
Features: black iron wire has good flexibility and elasticity, can be in annealing process control it's soft and hard degree, made by the high quality iron wire is made, mainly used in building industry as binding wire and cable tie. Silk number are mainly composed of 5 # - 38 # (silk by 0.17 4.5 mm) trait: better than ordinary black iron wire more soft, better flexibility, softness even, consistent color. USES: mainly used in construction, mining, chemical industry, wire welding, welding clothes hangers, reprocessing, etc. When annealed wire become soft, flexible degree increased, for building bind silk, binding reinforcement effect more.
