Nickel

Nickel

Nickel (Ni) is a lustrous, silvery-white metal with excellent corrosion resistance and high-temperature performance. It has a melting point of 1455 °C and is ferromagnetic at room temperature. Nickel is valued for its mechanical strength, ductility, and stability in aggressive environments. Its electrical and thermal conductivities are moderate but highly stable over time. Nickel naturally forms a passivating oxide layer, enhancing resistance to oxidation and corrosion. Widely used in alloys and electroplating, nickel supports applications in energy, electronics, aerospace, and advanced manufacturing. In scientific research, high-purity nickel is employed in catalysis, vacuum technology, and magnetics.

Goodfellow’s range of high-purity Nickel (Ni) products, including Nickel Rods, Sputtering Targets, Pellets, and Nanocrystalline Nickel Foils, are crucial for advanced research and industrial applications. Known for its exceptional corrosion resistance, high conductivity, and versatility, Nickel is extensively used in aerospace, electronics, and energy storage. Nickel-based materials are key in battery development, corrosion-resistant alloys, and semiconductor devices. Our Nickel products support laboratory and production innovation in materials science, electrochemical research, and thin-film deposition. With a broad range of forms and customized options, Goodfellow provides Nickel solutions that meet the needs of researchers and professionals across cutting-edge industries.
