Tungsten Carbide Rod Producing Countries
About 50 countries manufacture tungsten carbide rod in the world and the total output can reach to 27000t-28000t. The main producing countries are America, Russia, Sweden, China, German, Japan, England and France. The tungsten carbide rod market has reached the saturated condition so the competition is really fierce. China started to make tungsten carbide rod in the end of 1950s. After a long time research, the technique and output improve a lot in the 1960s-1970s. In 1970s, the tungsten carbide rod producing capability reached to 6000t, the total output reached to5000t which is second only to Russia and America, ranked the third place in the world.
About 600-700 enterprises produce tungsten carbide rod in the world. Among which the most competitive ones are Sandvik in Sweden and Kennametal in America. In 2000, tungsten carbide rod total sale is 88.72 billion dollars and they accounted for 40% of it.

Tungsten Carbide Round Rod
Tungsten carbide round rod is a shape for round rod, and the main material for tungsten carbide round rod is tungsten carbide. Tungsten carbide, also known as cemented carbide, is an extremely hard alloy made from tungsten and carbon that offers high wear resistance as well as good corrosion resistance. These tungsten carbide round rods are used for the manufacture of cutting tools for the metal, wood, plastic and other industries where hardness and wear corrosion resistance is required. Tungsten carbide round rods are available in standard lengths of 310 and 330 mm.
Tungsten carbide round rod has been ground to achieve the precise shape and size, and has a precision tolerance. The tungsten carbide round rod provides high wear resistance, and good corrosion and heat resistance. Tungsten carbide round rod is mainly applied in making drills, end mills and reamers. And it is also used for cutting, punching and measuring tools.

International solid carbide cutting tools industry status is mainly reflected in the following two aspects:
First, international solid carbide cutting tools industry status is reflected in that the output value of international solid carbide cutting tools the international is about $ 1.3 billion, of which PCB drill and micro-milling of 600 million (about 20% of micro cutter), the average unit price of 1 USD / support, about $ 600 million; metalworking of solid carbide cutting tools around 25 million (60 million or more cutters), the average price is about $ 30, with a total of about $ 700 million.
Secondly, international solid carbide cutting tools industry status is reflected in that the forefront of the solid carbide cutting tools is Germany, accounting for 60% market share. Asia, China, Japan, South Korea accounted for about 25%, North America 15%.

Tungsten Carbide Rod Corrosion Resistance in PH Value
Although tungsten carbide rod with cobalt binder has fairly good resistance to attack by acetone, ethanol, gasoline and other organic solvents as well as by ammonia, weak acids, and tap water. Exposure to formic, hydrochloric, hydrofluoric, nitric, phosphoric, sulfuric, and other strong acids, however, can result in a relatively rapid deterioration of the binder phase. Corrosion rates are affected also by temperature, the concentration and electrical conductivity of the corrosive agent, and by other environmental factors.
The following chart is the corrosion resistant details of tungsten carbide rod cobalt binder& tungsten carbide rod nickel binder in PH value.

Tungsten Carbide Rod Bending and Deformation Affecting Factors

Tungsten carbide rod bending and deformation affecting factors includes carbon gradient, cobalt gradient, temperature gradient and density gradient.
1.Carbon gradient. During the dewaxing and sintering process the carbon gradient would change continuously. Due to the different parts of the tungsten carbide rod has different decarburization and carbon pick-up capability, carbon gradient then comes into being. Setting time in different parts also changes which causes liquid phase moves to the setting section first and cause the bending and deformation of tungsten carbide rod.
2.Cobalt gradient. During the vacuum sintering process of tungsten carbide rod, the wettability of the cobalt for different parts causes the liquid cobalt moves ups and downs.
3.Temperature gradient. During sintering process, liquid cobalt often moves to the high temperature section. The higher the temperature, the higher the cobalt contents will be, thus the deformation of tungsten carbide rod will be more serious.
4.Density gradient. Due to the insufficient pressure and uneven surface of rolled material, density gradient becomes another important factor. Normally, tungsten carbide rod with low density will bend and deform more easily.
