Key words: black annealed binding wire, annealed back wire, annealed wire, black annealed iron wire, black annealed wire, black binding wire
Process :
Black iron wire includes cold drawing wire ,annealed wire and black oiled wire,all of them use the high quality wire rod which diameter is 6.5mm as raw material.
Cold drawing wire is produced through wire-drawing;annealed wire is though wire-drawing and anneal to finish.
we can do it into straight cutting wire,U type wire and also do according to users' special requirement
Roll the hot metal billet into a 6.5mm thick steel strip, that is, the wire rod, and then put it into the wire drawing device to draw the wire of different diameter, and gradually reduce the hole diameter of the drawing disk for cooling, annealing and coating. The processing technology  is made into a variety of different specifications of wire. It contains    ingredients: iron, cobalt, nickel, copper, carbon, zinc, and other        elements.

Black Annealed Wire Features:
Carbon steel wire with annealed heating treatment 
Soften and flexible character 
Low costs and economy 
Easy to handle or install 
Continuous coils and uniform diameters
Various sizes and packages available upon request Ideal for binding or mesh making.

Characteristics: softer than ordinary black iron wire, more flexible, uniform softness and consistent color.
Uses: Mainly used in construction, mining, chemical, welding mesh, welding hangers, reprocessing, etc. After annealing, the wire becomes soft and the flexibility increases. The effect of building the wire and tying the steel bar is even more effective.
At present, the production of annealed wire and steel wire is generally processed by drawing and galvanizing. In 1976, the Guangzhou galvanized iron wire factory successfully applied the new technology of electrolytic pickling, high-pressure washing and card electric drying in China, and successfully produced the continuous drawing line, which changed the drawing process from intermittent production to continuous production, which reduced the labor intensity. Reduced metal consumption. At that time, the domestic wire factory has been able to produce wire rope, spoke wire, rib wire, spring wire, bicycle saddle spring wire and other products. In the 1980s, hot-dip low-carbon steel wire, fan mesh wire, carbon structural steel wire, and bed steel wire were also introduced.
Packing: The packaging of black iron wire is the same as the packaging of galvanized wire. It is made of plastic, and it is wrapped in a thin layer of plastic, and then wrapped in a hemp or woven bag. !
Black Annealed Wire Applications:
Black Annealed Wire is mainly processed into coil wire, spool wire or big package wire. Annealed wire is used as tie wire or baling wire in building, parks and daily binding. Besides, black annealed wire is mainly used as industrial wire, construction wire, industrial bale tie wire and constructional tie wire, etc.
