    Product Description

    Niobium carbide powder is light brown and has a metallic luster. In industrial applications, niobium carbide powder can be used to manufacture cermet, heat-resistant alloys and cemented carbide, and can also be used as an additive to cemented carbide, which can significantly improve the thermal hardness and thermal shock resistance, thermal compression resistance, and oxidation resistance of cemented carbide. In addition, niobium carbide can also be used to make cutting tools, with good thermal hardness, thermal shock resistance and thermal oxidation resistance.

    Quality control system


    Huarui has strict quality management system. We test our products first after we finish our production, and we test again before every delivery, even sample. And if you need, we would like to accept third party to test. Of course if you like, we could provide sample to you to test.

    Our product quality is guaranteed by Sichuan Metallurgical Institute and Guangzhou Institute of Metal Research. The long term cooperation with them can save a lot of testing time for customers.
