L605 Cobalt Chromium Alloy Sheet Description
L605 Cobalt Chromium Alloy Sheet consists of cobalt, chromium, tungsten and nickel. It is used in applications requiring high‐temperature performance. Quantitative tests indicate that mechanical properties are retained up to 1 500°F (816°C) and oxidation resistance is maintained up to 1 800°F (980°C). The material is confirmed to resist sulfidation, wear and galling.
L605 Cobalt Chromium Alloy Sheet is applied in situations that require moderate mechanical strength combined with high‐temperature capability. It is used in aerospace components, gas turbine engines and chemical processing equipment. The alloy is non-magnetic and demonstrates corrosion resistance in environments containing hydrochloric acid, nitric acid and sea water, thereby meeting the requirements of various scientific and industrial applications.
