Superalloys are high-performance materials designed to withstand extreme temperatures and harsh environments. They are primarily used in applications like jet engines and gas turbines, where durability and strength are crucial. These alloys typically contain a combination of nickel, cobalt, and iron, along with other elements that enhance their properties. The unique composition of superalloys allows them to maintain their mechanical strength and resist oxidation and corrosion at elevated temperatures. This makes them essential in industries such as aerospace and power generation, where reliability and efficiency are paramount for performance and safety.
