Classification of cemented carbide

2021-03-18

1. Tungsten-cobalt cemented carbide:

The main components are tungsten carbide (WC) and binder cobalt (Co). The grade is composed of "YG" (the initials of the Chinese pinyin of "hard and cobalt") and the percentage of the average cobalt content. For example, YG8 means that the average WCo=8%, and the rest is tungsten-cobalt cemented carbide of tungsten carbide. Generally, tungsten-cobalt alloys are mainly used in: cemented carbide tools, molds and geological products.

2. Tungsten-titanium-cobalt cemented carbide:

The main components are tungsten carbide, titanium carbide (TiC) and cobalt. The grade consists of "YT" (the initials of the Chinese pinyin of "hard and titanium") and the average content of titanium carbide. For example, YT15 means that the average TiC=15%, and the rest is tungsten carbide and cobalt tungsten-titanium-cobalt cemented carbide.

3. Tungsten-titanium-tantalum (niobium) hard alloy:

The main components are tungsten carbide, titanium carbide, tantalum carbide (or niobium carbide) and cobalt. This kind of cemented carbide is also called general cemented carbide or universal cemented carbide. The grade is composed of "YW" (the initials of the Chinese Pinyin of "hard" and "myriad") plus a sequence number, such as YW1.

Advantages of cemented carbide:

Cemented carbide has high hardness, strength, wear resistance and corrosion resistance, and is known as "industrial teeth". It is used to manufacture cutting tools, knives, cobalt tools and wear-resistant parts, and is widely used in military, aerospace and aviation , Mechanical processing, metallurgy, oil drilling, mining tools, electronic communications, construction and other fields, with the development of downstream industries, the market demand for cemented carbide continues to increase.

And in the future, the manufacturing of high-tech weapons and equipment, the advancement of cutting-edge science and technology, and the rapid development of nuclear energy will greatly increase the demand for high-tech and high-quality and stable cemented carbide products.
