The feasibility of producing cemented carbide with niobium tantalum is discussed in detail

In recent years due to tantalum raw material water up, so that the price of tantalum containing alloy all the way up. But because people think that the role of tantalum in the carbide can not be replaced with other raw materials, so the face of the price rise is seem powerless. We know that the material is very similar to the performance of tantalum is niobium, and a mention of niobium most people will immediately think of alloy brittle However, after a correct understanding of the characteristics of tantalum and niobium, it has been carefully designed to use niobium tantalum or part of niobium tantalum is completely feasible, and even in some alloy types.
