Silicon Metal 441 contains maximum impurities of 0.4% iron, 0.4% aluminum, and 0.1% calcium. This balanced composition makes it widely used in aluminum alloy production, silicone compounds, and chemical industries. It offers a good combination of purity and cost-effectiveness, making it suitable for general applications.
Silicon Metal 3303, on the other hand, has lower aluminum (0.3%) and calcium (0.03%) content compared to 441. With higher purity and fewer impurities, 3303 is preferred in industries that require stricter quality standards, such as high-performance aluminum alloys, chemical processing, and special materials for electronics.
