For the production of ingots of aluminum products used in the form of an aluminum bar. Such a bar has a trapezoidal cross section, and one or more kinks - in the cross-sectional constrictions are used to divide the ingot. These semi-finished products - aluminum ingots, has an extensive range of mass and chemical composition (e.g., aluminum or aluminum AD1N A6). The form of ingots is determined by way of casting. The shape of pigs rules are not strictly regulated. There are restrictions only on the maximum weight of the ingot - Aluminum ingots (ingot) must not weigh more than two hundred kilograms. Form release more weight is the aluminum slab or bloom. aluminum slab is a rectangular blank (weight not more than 45 tons). Blum - blank square mass not exceeding 15 tons. Smelted aluminum ingots and bullion, is often used as primary and secondary materials. In the second case it acts as a secondary raw material of aluminum scrap and waste. Industrial aluminum ingots often contain copper, magnesium, manganese, silicon, zinc and incidental impurities is not, for the most part a technological aluminum ingot alloy with additions of alloying elements. Alloyed aluminum acquires new physical and chemical properties. Thus, aluminum-magnesium alloys are resistant to corrosion and high weldability (for example, aluminum alloy AMg6) aluminum ingot of the alloy claimed in mechanical engineering. Other brands, having a low resistance to corrosion, have high strength and toughness (aluminum alloy AD31, duralumin). Other alloys because of their strength and ductility at the same time used in the aviation industry (aluminum alloy VD17). For the production of bicycles popular aluminum 7005. A special place is occupied alloys produced by powder metallurgy - Sintered aluminum alloys. In this case, the material is made by sintering fine powder.
