Multiple Carbides

CMTRM is the first enterprise engaged in the smelting and production of tungsten, molybdenum, tantalum and niobium in China. Through decades of technology accumulation and precipitation, the company has mastered the processing characteristics of various kinds of powder from raw ore control, smelting technology to powder preparation.

Product Description

复式碳化物Multiple Carbides

产品用途:

是生产硬质合金的重要原料,能够提高硬质合金的硬度,但同时降低了合金的横向断裂强度和相对密度。

Application:

It is an important raw material for the production of cemented carbide. It can improve the hardness of cemented carbide, but reduce the transverse fracture strength and relative density of cemented carbide at the same time.
