What is Tungsten Carbide? Tungsten Carbide is the result of joining or alloying carbon with Tungsten, hard and thick metal with a high softening point. Tungsten Carbide events a profound dark tone in its untreated, normal state however can be cleaned, sandblasted, or cut to give it a wide scope of completing feel. There are some interesting facts about Tungsten Carbide: Tungsten carbide is two to three times harder than
Today we talk about how to detect the hardness of cemented carbide. 1. Hardness testing method Hard alloy hardness testing mainly adopts Rockwell hardness tester to test HRA hardness value. PHR series portable Rockwell hardness tester is very suitable for testing the hardness of cemented carbide. The weight accuracy of the instrument is the same as that of the desktop Rockwell hardness tester, and it is very convenient to use and carry. Cemented carbide is a kind of metal. The hardness test can reflect the difference in mechanical properties of cemented carbide materials under different chemical composition, structure and heat treatment process conditions. Therefore, the hardness test is widely used in the inspection of cemented carbide properties and supervision of heat treatment. The correctness of the process and the research of new materials. 2. Hardness testing features It is a non-destructive test, and the test method is relatively simple. The hardness test of cemented carbide has strong adaptability to the shape and size of the test piece, and the test efficiency is high. In addition, there is a certain correspondence between the hardness of cemented carbide materials and other physical properties. For example, hard alloy hardness test and tensile test are basically testing the ability of metal to resist plastic deformation, and these two tests are testing the similar characteristics
