Nickel is a shiny silvery-white metal widely used in steel, alloys, and coatings around the globe. It ranks as the 5th most common element on Earth and is one of the four ferromagnetic metals, alongside iron, cobalt, and gadolinium. Nickel is extensively utilized for corrosion protection in the electroplating industry and plays a crucial role in advanced applications within the aerospace, electronics, and medical sectors.
Properties | Nickel has a high melting point of 1453°C, is magnetic at room temperature, and offers excellent resistance to corrosion and oxidation. It is very tough, highly malleable, and easy to weld or alloy. |
Applications | Nickel is used in stainless steel, heat-resistant alloys, electroplated coatings, batteries, electronic components, and jet engines. It is also utilized in medical equipment and architectural applications. |
Approximately 65% of all nickel is used in the production of stainless steel, followed by 20% in high-performance alloys for aerospace and defense among others. Due to their outstanding performance at high temperatures, nickel alloys like Inconel and Hastelloy are indispensable in turbine jet engines, where temperatures reach up to 1480°C and the pressure up to 40 atmospheres.
Additionally, nickel is a favorite in the food industry, chemical plants, kitchen products, and even coins and batteries. Thanks to its versatility and reliable properties, nickel is used worldwide in more than 300,000 end products.

Nickel is primarily mined in countries such as Indonesia, the Philippines, Russia, and Canada. There are two main methods: from sulfide ores through smelting processes, or from laterite ores through acid or ammonia extraction. After extraction, the nickel is purified and processed into powder, pellets, or anodes, ready for use in alloys, electroplating, or battery applications.
