Aluminum ingot (alloy ingot) is used alumina - cryolite produced by electrolysis. Aluminum ingot (alloy ingot) into the following industrial applications there are two categories: cast alloy ingot and deformed alloy ingot. Casting alloy and aluminum alloy ingot casting method is based on the production of aluminum castings; deformation of aluminum alloy ingot and processing methods based on pressure from the production of aluminum processed products: plate, belt, foil, tube, rod, type, wire and forgings. In accordance with & lt; & lt; remelting aluminum ingot & gt; & gt; national standards, "with the aluminum ingot remelting (alloy ingot) by chemical composition is divided into six grades, namely Al99. 85, Al99. 80, Al99. 70, Al99. 60, Al99 . 50, Al99.
