Superalloys are a group of high-performance materials that are designed for use in extreme environments where high temperatures, stress and corrosion resistance are required. The term superalloy is often used interchangeably with high-performance alloy, advanced alloy or special alloy. However, each of these terms has a slightly different connotation. High-performance alloy generally refers to a metal that has been specially formulated to exhibit specific properties such as strength, durability or corrosion resistance. Advanced alloy refers to alloys that are developed using advanced manufacturing techniques or are made using non-traditional methods such as powder metallurgy. Special alloy encompasses alloys that have unique or specialized properties, such as those used in aerospace, biomedical or nuclear applications. Ultimately, regardless of the term used, superalloys are a critical component in advanced manufacturing and specialized applications.
