After annealing, the wire will become soft, flexibility will increase, iron is a relatively active metal, and more active than hydrogen, so it is a good reducing agent. At room temperature, iron is not easy to react with oxygen, sulfur, chlorine and other non-metallic elements in dry air. Its production cost is lower, its use and scale are also relatively wide, and it has better protective function. Therefore, it is an important material for steel parts in strict working environment.

2. To avoid galvanized iron wire being gripped by tools like pliers or hardened claws, when the wire suffers from tension or bending stress, scoring or pooping on the surface can lead to damage.

Black iron wire application in the process, the main is through the hot metal billet rolling into six point five mm wire rod, and then put it in the drawing into a line of different diameter, the plant and then gradually narrow drawing plate aperture, cooling and annealing, plating process, such as making a variety of different specifications of the wire, the wire compared with ordinary black iron wire, will be more softer, Softness is also very uniform, color is also consistent, widely used in the construction industry, mining, chemical industry, welding mesh, welding coat hanger, reprocessing industry and so on.

It is arguably, the strongest aluminum grade in the 6000 series used for making aluminum profiles for windows and doors. 6063 grade is extruded and features some of the ideal properties for doors and windows.
