The wire is one of the types of metal products, the wire is characterized by a very large ratio of its transverse and longitudinal dimensions. Like other types of rolled metal, the wire is made of steel, aluminum, copper, nichrome and many other types of metals and alloys. The production of wire is carried out by drawing metal through a series of successively decreasing holes - fillers, which makes it possible to obtain a wire of any required diameter. A metal wire is a long thread with high strength, sufficiently high flexibility and, depending on the material from which the wire is made, different electrical conductivity. The wire is used in all industries and a huge number of products and goods are made from it, both for industrial and domestic purposes. Today's industry produces various types of wire, differing from each other in the metal or alloy from which the wire is made, in physical and chemical properties, and also in the field of application.
