Tungsten carbide is a hard metal that is used in manufacturing cutting tools and wear-resistant parts like molds. It can be combined with other metals to produce other types of carbides. One example of this combination is tungsten carbide-cobalt which is the most popular Tungsten carbide alloy with the combination of hard material tungsten carbide and binder material cobalt.<\/p>\r\n
Tungsten carbide is manufactured by a series of production processes like powder mixing, pressing, sintering, and so on. During the sintering process, the binder material like cobalt will melt and help the mixing and binding of the tungsten carbide to increase the compaction and density of the final alloy.<\/p>\r\n
Tungsten carbide is one of the best candidates for recycling. While it is a very valuable metal, it can also be a source of scrap. For example, scrap tungsten carbide can be melted down and refined to form new pieces of tungsten carbide.<\/p>\r\n
Porozmawiamy o 6 kluczowych parametrach materia\u0142owych w\u0119glika wolframu. W \u015brodowisku akademickim w\u0119glik spiekany jest materia\u0142em stopowym o wyj\u0105tkowo wysokiej twardo\u015bci i dobrej odporno\u015bci na zu\u017cycie, kt\u00f3ry jest wykonany z proszku w\u0119glika wolframu (faza utwardzona) z metalu ogniotrwa\u0142ego o wysokiej twardo\u015bci jako g\u0142\u00f3wnego sk\u0142adnika i metali, takich jak kobalt i nikiel (faza wi\u0105\u017c\u0105ca) jako spoiwa, poprzez mielenie kulowe, prasowanie i spiekanie. Mo\u017cemy to po prostu rozumie\u0107 jako materia\u0142 metalowy o wysokiej twardo\u015bci i dobrej odporno\u015bci na zu\u017cycie. W\u0119glik wolframu jest zwykle okre\u015blany ze wzgl\u0119du na w\u0142a\u015bciwo\u015bci fizyczne, ale jego kompatybilno\u015b\u0107 chemiczna mo\u017ce si\u0119 r\u00f3\u017cni\u0107 w zale\u017cno\u015bci od spoiwa metalu. Na przyk\u0142ad w\u0119glik wolframu zwi\u0105zany z niklem jest bardziej odporny na korozj\u0119 ni\u017c w\u0119glik wolframu zwi\u0105zany z kobaltem.<\/p>\r\n\r\n\r\n\r\n
According to the relevant parameters of physics, the mechanical properties of cemented carbide are mainly shown in the following material parameters:<\/p>\r\n
The hardness of Tungsten Carbide is a function of its density, or how much of a material’s mass is contained in a unit volume. The SI unit for this property is kilograms per cubic meter, and the English unit is pounds per cubic foot. For a cubic inch of Tungsten Carbide, its density is 14.5 g\/cm3. And for different grades of tungsten carbide-cobalt alloy, the density can vary from 13-15g\/cm^3. And the hardness can go from HRA86 to HRA95 which is one of the hardest materials in the world, second only to diamond.<\/p>\r\n\r\n\r\n\r\n
The bending strength of cemented carbide is lower than that of high-speed steel. Even YG8 cemented carbide with high bending strength has only about half of that of high-speed steel. The higher the cobalt content in cemented carbide, the higher its strength. With the same cobalt content, the bending strength of WC tic Co alloy decreases with the increase of TiC content. In addition to the types of carbides, the size of WC grains also affects the strength of cemented carbide. The bending strength of coarse-grained cemented carbide is higher than that of medium grain cemented carbide.<\/p>\r\n\r\n\r\n\r\n
