The production of stainless steel: Nickel is a crucial ingredient in stainless steel, with typical concentrations ranging from 8 to 12% nickel. This addition enhances the steel's corrosion resistance and improves its strength and ductility, making it an ideal choice for a variety of applications.
Alloys: Nickel is utilised in a range of alloys, including those with copper (for coinage and marine applications) and with chromium (for high-performance applications). Superalloys, which often contain significant amounts of nickel, are used in the aerospace and high-temperature industries.
Batteries: Nickel is a key component in rechargeable battery systems, particularly in nickel-metal hydride (NiMH) batteries and nickel-cadmium (NiCd) batteries. It is crucial for the performance and longevity of these batteries.
Electroplating: Nickel plating is a process used to protect metals against corrosion and wear, as well as to enhance their aesthetic appeal. It provides a hard, polished finish that enhances the durability of the underlying metal.
Catalysts: Nickel is employed as a catalyst in a number of chemical reactions, including those involved in the hydrogenation processes used in the production of margarine and other food products.
The chemical industry employs nickel compounds, such as nickel sulfate, in the production of catalysts and in electroplating processes.
In marine applications, nickel alloys are highly resistant to seawater corrosion, making them ideal for marine applications, including shipbuilding and offshore structures.
