Black Annealed Wire
Black annealed 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.
