Cobalt Alloys | Uses and Characteristics

Steel, aluminum, titanium, zirconium, the list of raw materials used for metal components can go on and on. With so many options, deciding on the right type of material for your project can get overwhelming. It’s important to understand the properties, benefits, and applications of different types of metals to see which best fits your specific needs. Keep reading to learn all about the popular metalworking material like cobalt alloy.

What are Cobalt Alloys?

Cobalt alloys are metal alloy. But it’s not just any metal alloy. This alloy is a cobalt-chromium “superalloy”. It was designed specifically for high wear resistance and superior performance in hostile environments. It’s resistant to cavitation, erosion, corrosion, galling, and abrasion. The combination of Cobalt and Chromium also enables the metal to have an extremely high melting point. It is typically used in temperatures ranging from 600 – 1112 °F (315 – 600 °C). Molybdenum or tungsten and a small amount of carbon are also sometimes added to cater to specific applications. Cobalt alloy was developed in the early 1900s as an alternative for cutlery that stained easily.

What are Cobalt Alloys Applications?

Due to its favorable properties, there are numerous cobalt alloy applications. Some of the major applications include saw blade facing and acid-resistant machine parts. It has greatly improved the production of poppet valves, valve seats, and exhaust valves for internal combustion engines. This alloy is also preferred for M2HB machine gun and machine gun barrels, medical parts (e.g. artificial hip joints, bone replaces, dental cast structures, etc.), and turning tools for lathes.
