Vanadium disks are made from vanadium, which is a transition metal valued for its high tensile strength, hardness and resistance to corrosion. Available in 938 variations, they provide options for different levels of strength, durability, weight, size and cost. Potential applications include being used in high-performance engines and aircraft due to vanadium's strength at high temperatures. Vanadium Disk are a great example of our in-house ability to create high-quality customized materials.
