Approximately 70% of all nickel produced globally is used in the manufacture of stainless steel. Nickel imparts critical properties to the alloy — corrosion resistance, ductility, formability, and strength at both high and low temperatures. The most common grade, austenitic stainless steel (304/316), contains 8–12% nickel. It is used in construction, food processing equipment, kitchenware, medical devices, and architectural elements where long-term durability is essential.

Nickel is a strategic raw material for the energy transition. Class 1 nickel (≥99.8% purity) is used in NMC (Nickel-Manganese-Cobalt) and NCA (Nickel-Cobalt-Aluminum) cathode chemistries for lithium-ion batteries. Higher nickel content increases energy density, allowing electric vehicles to achieve longer driving ranges. Demand from the EV sector is projected to grow significantly through the next decade as the global automotive industry transitions toward electrification.

Nickel-based superalloys (such as Inconel, Hastelloy, and Monel) are designed to retain mechanical strength and resist creep and corrosion at temperatures exceeding 1000°C. These alloys are indispensable in jet engine turbine blades, combustion chambers, gas turbines for power generation, and rocket components. Without nickel superalloys, modern aviation and space exploration would not be possible.

Nickel electroplating deposits a thin protective layer on metal surfaces to prevent corrosion, reduce wear, and improve aesthetic appearance. It is widely used in automotive components (bumpers, trim), plumbing fixtures, electronics, and consumer goods. Electroless nickel plating is also applied in oil & gas, chemical processing, and printing equipment where uniform thickness on complex geometries is required.
