Non-ferrous metal is presented by products from aluminum, copper, brass, zinc, bronze, lead, etc. In view of the high cost of these alloys metal rolling from them, in comparison with ferrous metal, rather expensive. Though, It should be noted, as volumes of use of this type of material are much lower. Non-ferrous metal is irreplaceable at construction of premises, and its different types, at establishment of a water supply system and systems of gas supply, at construction of bridges. From color metal rolling produce steel fencings, balcony protections, a ladder handrail. Non-ferrous metal is applied in road construction, mechanical engineering, shipbuilding, agriculture, and also in production of household appliances. The demand of material is proved by existence of high operational qualities. As non-ferrous metal is presented by different alloys, each of which has the unique properties, at the choice of material it is necessary to consider its further mission. So, heat conductivity, small weight, an excellent malleability, durability, stability before low temperature indicators of aluminum does it irreplaceable in industrial spheres, aircraft industry, at production of a foil. Flexibility and good conductivity of copper give the chance to use it by production of a cable, and also in power plant engineering. Thanks to durability, reliability and corrosion firmness became, products from this alloy are applied not only in industrial and construction branches, but also in the solution of household tasks. Feature of non-ferrous metals is their ability to change the properties as a result of training. Material easily gives in to different ways of processing: to stamping, rolling, forging, pressing, cutting, welding and soldering.
