products?informationAluminum ingots in our daily industrial is a raw materials, according to the national standard (GB/T 1196-2008) should be called & quot;remelting aluminum ingot& quot;, but we call & quot;aluminum ingot& quot;. It is with the alumina cryolite produced by electrolysis. After entering the industrial application of aluminum ingots in two categories: Aluminum Alloy Aluminum Alloy casting and deformation. Cast aluminum and aluminum alloy is a casting method for the production of aluminum castings; deformation of aluminum and aluminum alloy production of aluminum processing products: plate, belt, foil, tube, rod, type, line and forging. According to the national standard & quot;aluminum ingots for remelting by chemical composition is divided into 8 grades, namely Al99.90, Al99.85, Al99.70, Al99.60, Al99.50, Al99.00, Al99.7E, Al99.6E& quot; (Note: Al number is aluminum content). Someone called & quot;A00& quot; is actually 99.7% aluminum, aluminum purity aluminum, called standard aluminum in the London market& quot;. We all know that in 50s our technical standards are from the former Soviet Union, & quot;A00& quot; is the national standard in the Soviet Russian brand, & quot;A& quot; is the Russian alphabet, rather than English & quot;A& quot; word, nor the Chinese phonetic alphabet & quot;A& quot; and the international community, & quot;said standard aluminum is more precise. Is the standard aluminum containing 99.7% aluminum ingots, registered in the London market is that it.SpecificationsITEMComposition(%)AL ≥Impurities ≤FeSiCuGaMgZnOthersTotalAL99.9099.90.070.050.0050.020.010.0250.0160.1AL99.8599.850.120.080.0050.030.020.030.0150.15AL99.7A99.70.20.10.010.030.020.030.030.3AL99.7099.70.20.120.010.030.030.030.030.3AL99.6099.60.250.160.010.030.030.030.030.49AL99.5099.50.30.220.020.030.050.050.030.5AL99.00990.50.420.020.050.050.050.051Aluminum ingot surface should be smooth, no slag, cracks, porosity, surface crack length is less than 1.5mm, the surface of slag and the depth of the crack edge wrinkles will not exceed the 2mm section, no crack, porosity and sla
