Why Compare FeSiMg Alloy 5%, 6% and 7% for Magnesium Treatment? Three magnesium levels exist because no single level covers every heat. A foundry treating thin sections in a small ladle is over-treating if it uses a 7% alloy; a plant pouring thick walls from a large ladle is under-treating with a 5%. The choice sits between two failures: too little magnesium leaves flake graphite and a scrap casting, while too much leaves shrinkage, dross and a hard, brittle structure that
