What will affect the performance of the aluminum ingot in the process of casting?
In our daily industrial raw materials called aluminum ingot, according to the national standard (GB/T1196-2008) should be called "remelting with aluminum ingot", but we are used to "aluminum ingot"". It is with the alumina cryolite produced by electrolysis.
We all know that in 50s our technical standards are from the former Soviet Union, "A00" is the national standard in the Soviet Russian brand, "A" is the Russian alphabet, rather than English "A" word, nor the Chinese phonetic alphabet "A" and the international community, "said standard aluminum is more precise. Standard aluminium is the aluminum ingot containing 99.7% aluminium, which is registered in the London market.
There are two major types of aluminum ingot after industrial application: cast aluminum alloy and wrought aluminum alloy. Cast aluminium and aluminum alloy are used to produce aluminium castings by casting method. Wrought aluminium and aluminium alloy are produced by pressure process. They are plates, belts, foils, tubes, rods, shapes, wires and forgings. According to the national standard "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" (Note: Al number is aluminum content). Some people call "A00" aluminum, in fact, is aluminum containing 99.7% purity aluminum, called standard aluminum in the London market".
