Cemented carbide products with cobalt-nickel binders are essential materials widely used in industrial, military, metallurgical, petroleum drilling, mining tools, and construction applications. These high-performance materials combine the hardness of carbides with the toughness of metallic binders, making them indispensable in demanding environments. However, despite their robust nature, these products require a Safety Data Sheet (SDS) to ensure safe handling, processing, and regulatory compliance. This article explores why an SDS is necessary for cemented carbide products with cobalt-nickel binders, detailing their composition, hazards, safety measures, and regulatory requirements.
