For manufacturers that can industrially produce magnesium content higher than 99.99%, we collectively refer to magnesium ingots that meet the national standard of 99.95% to 99.99% as “high-purity magnesium”, without deliberately distinguishing between “high-purity magnesium” and “ultra-purity magnesium”. In addition, the titles of magnesium ingots are also very complicated, such as “magnesium ingots”, “first-class magnesium ingots”, “secondary magnesium ingots”, “metal magnesium ingots“, “metal magnesium”, “magnesium metal” and so on. The name that everyone is usually used to actually refers to the general magnesium ingot.
