Tungsten carbide grades and applications:
In the industrial field, tungsten carbide is widely used. As the world’s largest producer, China has nearly 900 cemented carbide manufacturers, each with an independent grade system. Different grades vary in composition and performance, and selecting the right tungsten carbide grades is key to maximizing material efficiency.
This article will analyze China’s national standard cemented carbide grades and compare them with international ISO standards and U.S. C-series standards to provide a clear selection reference.
