What’s the aluminium ingot

Aluminum, our daily industrial raw material is called aluminum ingot. According to the national standard (GB/T1196-93), it should be called “remelting aluminum ingot”, but everyone is used to “aluminum ingot”. It is produced by electrolysis using alumina-cryolite. There are two main categories of aluminum ingots after entering industrial applications: cast aluminum alloys and deformed aluminum alloys. Cast aluminum and aluminum alloy are castings for producing aluminum by casting method; deformed aluminum and aluminum alloy are processed products for producing aluminum by pressure processing method: aluminum plate, aluminum strip, aluminum foil, aluminum tube, aluminum rod, aluminum profile, aluminum wire and aluminum Forgings. According to the national standard of «Aluminum ingot for remelting», "Aluminum ingot for remelting is divided into six grades according to chemical composition, namely Al99.85, Al99.80, Al99.70, Al99.60, Al99.50, Al99. 00" (Note: the number after Al is the aluminum content). At present, some people call "A00" aluminum, which is actually aluminum with an aluminum purity of 99.7%, and is called "standard aluminum" in the London market. Everyone knows that China’s technical standards in the 1950s came from the former Soviet Union. “A00” is the Russian brand in the Soviet national standard. “A” is the Russian alphabet, not the English “A”, nor the Chinese phonetic alphabet. "A". When it is in line with international standards, it is more accurate to call "standard aluminum". Standard aluminum is an aluminum ingot containing 99.7% aluminum, which is registered on the London market.
Aluminum foil with moisture, easy to carry, safety and health advantages, in the international packaging  industry is very widely used.
