What is Stellite

Stellite is a non-magnetic alloy which contains a variety of different metal components with the main elements being cobalt and chromium. They are designed to be resistant to wear and corrosion, that become one of the most popular new remarkable alloy materials in 21 century. Originally created to replace traditional metal cutlery, prone to staining and general wear and tear, Stellite alloys now offers so much more. While the toughness and heat resistance of Stellite alloys are some of the main benefits, they also reduce the amount of machine finishing possible.



CERM’s Stellite

We CERM started the R&D and creation of Stellite alloy since 2001 and grew to be one of the global reputable manufacturer of Stellite later.  CERM offers many types of Stellite alloys composed of varying quantities of Co, Cr, Mo, W, Fe, Ni, B, Al, C, Mg, Si, Ti, S etc in different proportions. Most Stellite alloy compositions contain at least four to six of the listed elements and tailor-made composition is available upon the customer’s request. They combine excellent mechanical wear resistance, especially at high temperatures, with very good corrosion resistance.

Our Stellite alloys are available for purchase in the following product forms:

  • All Engineered Components

Our Stellite uses

  • Stellite alloys are used in the process of hardfacing.
  • Our Stellite alloys greatly improvised the manufacturing of poppet valves as well as the valve seats for valves. These alloys revolutionized the exhaust valves of internal combustion engines. The interval between maintenance of the valves and re-grinding of the valve seats was lengthened to a significant degree by reducing the erosion of the valves from hot gases.
  • The first third of M60 machine gun barrels (starting from the chamber) and the M2HB machine gun
  • are lined with Stellite. Stellite alloys were also used to make the shoulders and locking lugs of Voere Titan II rifles.
  • Stellite alloys are also frequently used to make the cast structure used for dental prosthesis.
  • Be used to create artificial hip joints as well as other bone replacements.
  • Stellite alloys have been used to manufacture turning tools for lathes. Stellite alloys have greater cutting abilities compared to carbon steel tools as well as some high speed steel tools. They are especially capable of cutting difficult materials like stainless steel.
