What are the standards for the price of aluminum ingots?

According to the national standard, "aluminum ingots for remelting are divided into six grades according to chemical composition, namely, al99.85, Al99.80, Al99.70, Al99.60, Al99.50 and Al99.00" (note: the number after Al is aluminum content). What some people call "A00" aluminum is actually aluminum with a purity of 99.7%, which is called "standard aluminum" in the London market. As we all know, China's technical standards in the 1950s all came from the former Soviet Union. "A00" is a Russian brand in Soviet national standards, and "A" is a Russian letter, not an English "A" or a Chinese phonetic alphabet. In line with international standards, it is more accurate to call it "standard aluminum". Standard aluminum is an aluminum ingot containing 99.7% aluminum.
