Today, Xiamen Betalent Carbide Co.,Ltd will explain the difference between the cemented alloy and carbide alloy for you. The carbide alloy belongs to cemented alloy, but the cemented alloy is not necessarily carbide alloy. The differences between them are:
(1) Cemented alloy is made of the refractory metal and hard compound of bonded metal by the powder metallurgy technology. It is an alloy material with a very high hardness.
High quality alloys have a range of excellent properties, such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance. Especially their high hardness and wear resistance can remain essentially unchanged even at 500°C. It still has a high hardness at 1000°C. The ceramic having certain properties of a metal.
(2) Carbide alloy is also known as tungsten titanium alloy or high speed steel or tool steel. The hardness is Vickers 10K, second only to the diamond. The term "sintered composite material" refers to sintered composite material consisting of at least one metal carbide.
Carbide alloy and cemented alloy have a range of excellent properties such as high hardness, wear resistance, high strength and toughness, heat resistance and corrosion resistance. The advantages of carbide alloy lie in its high hardness and wear resistance. Even at 1000℃, it still has a very high hardness. It can be called the second diamond. The grain size of the carbide composition (or phase) is usually between 0.2 and 10 microns.
(3) Carbide alloy is made by the technology of adding ferrotungsten to molten steel during the steelmaking. It is made from the raw materials of tungsten smelting, and it is also known as high speed steel or tool steel, and its tungsten content is generally 15 to 25%. Cemented alloy is sintered with cobalt or other bonded metals by powder metallurgy technology. Tungsten content is usually more than 80%. That is to say, all alloys whose hardness exceeds HRC65 can be called the cemented alloy.
