As a professional cobalt-chromium-alloy manufacturer, we offer different kinds of cobalt chromium alloy products, including Cobalt Chromium Alloy 3, Cobalt Chromium Alloy 4, Cobalt Chromium Alloy 6, Cobalt Chromium Alloy 12, Cobalt Chromium Alloy 20 etc, in this article we will intorduce for you.
What Is Cobalt Chromium Alloy
Cobalt Chromium Alloy is a range of cobalt-chromium alloys designed for wear resistance. It may also contain tungsten or molybdenum and a small but important amount of carbon.
Applications of Cobalt Chromium Alloy
Typical applications include saw teeth, hardfacing, and acid-resistant machine parts. Cobalt Chromium Alloy was a major improvement in the production of poppet valves and valve seats for the valves, particularly exhaust valves, of internal combustion engines. By reducing their erosion from hot gases, the interval between maintenance and re-grinding of their seats was dramatically lengthened.
While Cobalt Chromium Alloy remains the material of choice for certain internal parts in industrial process valves (valve seat hardfacing), its use has been discouraged in nuclear power plants. In piping that can communicate with the reactor, tiny amounts of Cobalt Chromium Alloy would be released into the process fluid and eventually enter the reactor.
Properties of Cobalt Chromium Alloy
Cobalt Chromium Alloy is a family of completely non-magnetic and corrosion-resistant cobalt alloys of various compositions that have been optimised for different uses. Cobalt Chromium Alloys display outstanding hardness and toughness, and are also usually very resistant to corrosion. Cobalt Chromium Alloys are so hard that they are very difficult to machine, and anything made from them is, as a result, very expensive. Typically, a Cobalt Chromium Alloy part is precisely cast so that only minimal machining is necessary.
