Tungsten carbide classification

1. Hard alloy tungsten cobalt:
The main ingredients are tungsten carbide (WC) and adhesive cobalt (CO). Its brand is composed of "yg" ("hard, cobalt" Chinese Pinyin character). For example, YG8 indicates the average WCO = 8%, and the rest are tungsten cobalt hard alloy with tungsten carbide. Generally, tungsten cobalt alloys are mainly practical: hard alloy knives, molds and ground mineral products.

2. Tungsten titanium cobalt hard alloy
The main components are tungsten carbide, titanium carbide (TIC) and cobalt. Its brand number consists of "YT" ("hard, titanium" Chinese pinyin first) and the average content of titanium carbide. For example, YT15 means a tungsten titanium cobalt -like hard alloy with an average TIC = 15%, and the rest are tungsten and cobalt content with tungsten carbide and cobalt.

3. Tungsten titanium hard alloy
The main ingredients are tungsten carbide, titanium carbide, carbonized (or carbonized) and cobalt. This kind of hard alloy is also called universal hard alloy or universal hard alloy. Its brand number is composed of "YW" ("hard" and "Wan" Chinese Pinyin first) plus the serial number, such as YW1.

Advantages of hard alloys:
Hard alloys have high hardness, strength, wear resistance and corrosion resistance. They are known as "industrial teeth" and are used to make cutting tools, tools, cobalt gear and wear -resistant parts. , Machinery processing, metallurgy, oil drilling, mine tools, electronic communications, and construction areas, accompanied by the development of downstream industries, the demand for the hard alloy market has continued to increase.
And in the future, high -tech weapons equipment manufacturing, advancement of cutting -edge science and technology, and the rapid development of nuclear energy will vigorously improve the demand for high -tech and high -quality stability.

Tungsten carbide has the chemical symbol WC, though in industry it may be referred to simply as carbide (although this name is also given to other similar compounds, especially titanium carbide and tantalum carbide). In its natural state, it is a fine grey powder, which can either be sintered (compacted using heat or pressure) onto a surface, or cemented (bound with a metal to form a solid).

Tungsten carbide comes in grades, depending on which binders have been used – these are commonly cobalt or nickel. Other carbides may be added in order to boost specific properties, especially with regards to density, hardness or transverse rupture strength.
