Incoloy 909
Description:
Nickel Incoloy 909 is a nickel-iron-cobalt alloy which is widely used in precision engineering due to its high strength and minimal thermal expansion. As is the case with all Incoloys, the Incoloy 909 features excellent corrosion/oxidation resistance, high strength at high temperatures, and exceptional material and surface stability under harsh conditions. Combining the above characteristics brings the Incoloy 909 in the category of high-performance “superalloys”, the development of which is based on the application of pioneering chemical and processing methodologies.
