Haynes 25 (L605) foil is a cobalt-based alloy composed primarily of cobalt (balance), with significant amounts of chromium (20%), tungsten (15%), and nickel (10%), along with smaller amounts of iron, molybdenum, and carbon. This composition gives it excellent strength, corrosion resistance, and high-temperature stability. The alloy maintains good mechanical properties, including a tensile strength of around 1,200 MPa, excellent creep resistance, and outstanding oxidation resistance at elevated temperatures (up to 1,100°C). These properties make it ideal for high-stress, high-temperature applications, especially in aerospace and chemical industries.
