UPM Cobalt Alloy L605 (UNS R30605) is a solid-solution-strengthened, cobalt-20chromium-15tungsten-10nickel alloy. This corrosion- and heat-resistant alloy is typically used for intermittent service up to 870 °C (1600 °F), and for continuous service up to 1095 °C (2000 °F), but usage is not limited to such applications. This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as forming and heat treating. Filing Code: Co-131. Producer or source: United Performance Metals.
