Did you know that cobalt is utilized in aviation? It's true! Cobalt alloys are used in jet engines because of their stability at high temperatures. They are corrosion and wear and heat resistant, making them perfect for components in challenging area applications. In this article, we will tackle the applications of cobalt alloys in aviation and how they help keep our planes running smoothly.

Cobalt Alloys: Why and How Used


Cobalt alloys have a long history in aviation. They were first used in jet engines in the early days of military fighter jets. The rationale for this is that cobalt alloys can withstand high temperatures without corroding or breaking down. This made them perfect for components in areas of the engine that are subject to extreme heat and stress.

How Are Cobalt Alloys Applied?

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

Cobalt Alloys of Today

Nowadays, cobalt alloys are still used in jet engines. They are also utilized in other parts of the plane, such as the brakes and wheels. Cobalt alloys help to make these components more durable and resistant to wear and tear. This means that they can last longer and perform better, even under the most challenging conditions.
