For more than 70 years, WC-Co materials have been used worldwide for numerous applications in tooling, mining equipment or wear parts. Unfortunately, it has been recently determined that the cobalt and tungsten oxides present risks and health issues. Furthermore, the worldwide demand for tungsten and cobalt has been continuously growing, although the mining stocks of both elements are limited, which increased their price over the years. This global context has led industrial companies to investigate alternative carbide based materials. Niobium carbides are increasingly considered to replace tungsten carbides for specific applications. Although those carbides present a slightly lower hardness, they have impressive wear properties and are twi...
