- About Us
Vanadium
Vanadium (V) is a lustrous, silvery-grey transition metal known for its high strength-to-weight ratio and excellent corrosion resistance. It has a melting point of 1910 °C and maintains structural integrity under extreme temperatures. Vanadium forms a stable oxide layer that protects it in oxidizing environments. Though not found freely in nature, it is typically sourced from vanadinite ores and petroleum residues.
Goodfellow’s range of Vanadium products, including Vanadium Disks, Pellets, Powders, and Sputtering Targets, supports advanced research in several high-tech industries. Vanadium is essential in areas such as battery technology, particularly in vanadium redox flow batteries, and high-performance steel alloys. It is also pivotal in the development of superconductors, aerospace components, and corrosion-resistant materials. Our Vanadium materials, known for their strength and conductivity, are ideal for research in energy storage, materials science, and electronics. These products cater to the needs of laboratory researchers and industry professionals, aiding innovations in metallurgy, nanotechnology, and energy efficiency.
