Process: will the hot metal slab rolling into 6.5 mm thick steel rod is, then place them in a drawing in the diameter of the different device pulling into line, and gradually reduce wiredrawing dish aperture, for cooling, annealing, coating, coating processing technology into different kinds of different specifications of the wire. It contains the components are: iron, cobalt, nickel, copper, carbon, zinc, and other elements.

Characteristics: more than ordinary black wire soft, flexibility, stronger, softness even, chroma consistent.

USES: mainly used in construction, mining, chemical, welding nets, welding clothes hangers, and processing, etc. After annealing wire become soft, increase flexibility, for building tied silk, binding reinforcement effect more.
