Nickel is one of the most common elements used today. What you may not know though is that it had very little commercial use until the 20th century. This was because of the difficulty of refining and extracting it.


The use of nickel is tied closely to the development of steel alloys. It built a reputation as a useful additive to different alloys, particularly stainless steels. This is because it could offer excellent corrosion and thermal resistance.

Today you can find a lot of alloys that contain nickel. As well as featuring in many types of steel, there are lots of materials where it is the principal element. This includes things like alloy 90 and NiCr 80:20. These are key for the development of products like jet engines and components for chemical plants.

Nickel’s melting temperature is 1453 degrees Celcius. This is much higher than other metals like aluminium and copper. But, it is lower than metals such as tungsten. The capacity to work at higher temperatures however is not just about the melting temperature. It also depends on how easy the metal is to work in these conditions. Nickel remains very workable, including retaining its weldability and ductility.

Additional attributes

Nickel and its alloys also have extra attributes that let them work at higher temperatures. They include their capacity to create a stable, thick oxide layer. When you heat this, it safeguards the nickel from attacks. It is possible for the layer to be many microns thick. This depends on the environment and temperatures which you expose your metal to.

Another interesting fact about nickel alloys is that they can resist carburisation. What usually happens is that metals absorb carbon at high temperatures. It happens with iron and steel. Doing so can make them harder. That can be an advantage in some cases but in others it can cause brittleness and other issues. Luckily, nickel can resist it.
