Black iron wire is a common used wire in our life. Black iron wire is made of high quality iron or steel. So black iron wire with high strength can be used to hang some heavy things. And our products with high tensile and elongation strength are not easy to be broken when using it. Compared with galvanized wire, black iron wire has poor corrosion resistance. But it cost less. We have two kinds of black iron wires. One is hard drawn wire, another is soft annealed wire. We can control the hardness of black iron wire during the annealing process. You can choose suitable one depends on your use.

Feature

High bearing capacity.

High tensile strength and elongation strength.

Good elasticity, softness and flexibility.

Chromaticity consistent.

Smooth surface.

Various sizes to meet different needs.

Application

This kind of product market mainly is the Middle East large cable plant, Europe and the United States and some domestic cable plants. The commonly used specifications are 0.20mm, 0.24mm, 0.28mm, 0.30mm and 0.40mm.

Black iron wire has good elasticity and flexibility, can control its hardness and softness in the annealing process, made of high quality iron wire, mainly used in the construction industry for binding wire and tying wire.
Process.

The hot metal billet is rolled into a 6.5mm thick steel bar or coil, which is then put into a wire drawing device and drawn into different diameters of wire, and gradually reduce the diameter of the wire drawing disc, cooling, annealing, coating and other processing processes to make a variety of different specifications of wire. It contains the following components: iron, cobalt, nickel, copper, carbon, zinc, and other elements.
