Cobalt Pellets are a form of cobalt metal offered by Goodfellow within their range of pellets. Cobalt is known for its high tensile strength and lustrous appearance. The pellets can be used as catalysts in chemical reactions or as additive materials for alloys, allowing manufacturers to introduce cobalt's advantageous properties into their end products. The cobalt pellets provide a convenient way to work with measured amounts of cobalt for small-scale research and development purposes.
