Features and characteristics of tungsten carbide rods

Tungsten carbide rods are mainly made of WC (tungsten carbide) and Co (cobalt) by metallurgical methods through powdering, ball milling, pressing, and sintering. The main alloy components are WC and Co. The composition content of WC and Co is different in different applications of carbide rods, which are used in an extremely wide range of applications. It is well known that cutting tungsten carbide rods are hard after quenching and tempering; they have good wear resistance and work well at high temperatures. Next, we take a look at the characteristics and features of tungsten carbide rods. Here are some answers.

Do you know what are the characteristics of a tungsten carbide rod?

Firstly, the tungsten carbide rod has high purity, low impurity content, and more stable physical properties. Secondly, spray drying technology is used, the material is protected by high purity nitrogen under fully sealed conditions, which effectively reduces the possibility of oxidation during the preparation of the mixture, resulting in higher purity and less pollution of the material. Thirdly, the density of the tungsten carbide rod is uniform: 300Mpa isostatic press is used for pressing, effectively eliminating the generation of pressing defects, and the density of the blanks is more uniform. Fourth, the tungsten carbide rod has excellent denseness, excellent strength, and hardness index. Tungsten carbide rod adopts marine low-pressure sintering technology, which effectively eliminates the air holes inside the long rod, and the quality is more stable. Fifthly, tungsten carbide rod adopts deep cooling treatment technology, which can improve the internal metallurgical organization of long rods, greatly eliminate internal stress and avoid cracks during the cutting and forming process of the product.

Properties of tungsten carbide rod.

Tungsten carbide products are divided into tungsten carbide rods, tungsten alloy cubes, tungsten alloy plates, and tungsten alloy balls depending on the shape of the product. The basic physical and chemical properties are similar, but they also have a high melting point, high density, high hardness, high strength, low coefficient of thermal expansion, high modulus of elasticity, wear resistance, high-temperature resistance, good thermal conductivity, etc. Of course, the specific properties of Tungsten carbide rods depend on the proportion of raw materials used. Most of them are alloy products with refractory tungsten as the hard phase and cobalt, nickel, iron, copper, and other metals as the binding phase. When the binding agent is copper, the color, melting point, density, and electrical conductivity of the tungsten carbide rod vary. As the copper content increases, the color of the tungsten carbide rod tends toward copper and the electrical conductivity is better. Tungsten Rods' melting point and density increase as the tungsten content increases.
