Alumel is a nickel-based alloy primarily composed of nickel, aluminum, and small amounts of other elements like manganese and silicon. It is known for its excellent resistance to oxidation and corrosion, making it suitable for high-temperature applications. Alumel is commonly used in thermocouples, which are devices that measure temperature by generating a voltage based on the temperature difference between two junctions. In addition to its use in thermocouples, Alumel is also utilized in various industrial applications, including aerospace and automotive industries. Its lightweight and durable properties contribute to improved performance and efficiency in these sectors, making it a valuable material in modern engineering.
