In the Rockwell hardness test, operators use different forces to detect the hardness of tungsten carbide, which are the different scales A, B, and C, namely HRA, HRB, and HRC. According to the hardness of the experimental material, scales with different hardness ranges are selected to represent:

Cemented carbide is made of refractory metal and binder by powder metallurgy process. It contains tungsten, cobalt, titanium, and other metal elements. Cemented carbide has a series of excellent properties such as high hardness, toughness, wear resistance, heat resistance, corrosion resistance, and high temperature resistance. It is known as "industrial teeth" and is used in the manufacture and military, aerospace, machining, metallurgy, oil drilling, mining tools, electronic communications, construction, and other fields.

Hardness is the ability of tungsten carbide to resist local deformation, especially plastic deformation, indentation, or scratches. Hardness is an index to measure the hardness of tungsten carbide, which can sensitively reflect the differences in chemical composition, metallographic structure, heat treatment process, and cold working deformation of metal materials.

Tungstencarbide hardness

As we all know, tungsten carbide is the second hardest tool material in the world, after diamond. Tungsten carbide is famous for its high hardness so it can be widely used in mining and oil, aerospace and machining, and so on. However, do you know how to measure the hardness of tungsten carbide? In this article, we are going to talk about this briefly.

These chip breakers are for traditional Stanley-type planes. To maximize your plane's performance, a thicker chip breaker (cap iron) can stabilize the blade's cutting edge, reducing vibration and chatter.

HRA: 60 kg load and a diamond cone indenter, used for materials with higher hardness. For example, steel sheet, and tungsten carbide.

Rockwell hardness tester is always used for detecting the hardness of tungsten carbide. The advantage of Rockwell hardness testing is that materials with higher hardness can be measured by changing the test scale. The test is easy to operate and will not destroy the tungsten carbide products.

Dec 27, 2022 — What are the twelve standard types of milling cutter? · End mill: An end mill is a milling cutter that has a cylindrical shape and a flat bottom.

The hardness of tungsten carbide is generally measured by Rockwell hardness. Rockwell hardness is an index to determine the hardness value by the depth of indentation plastic deformation, with 0.002 mm as a hardness unit.

Set your breaker very close to the cutting edge to best prevent tear-out. These chip breakers are 3mm (0.118") thick, almost twice as thick as a stock chip breaker.

According to different force methods, there are two ways to measure the hardness of tungsten carbide: the pressing method and the scribing method. In the pressing method, it can be divided into the static test method and the dynamic test method according to the different acceleration speeds. Among them, the static test method is the most commonly used, including Brinell hardness, Rockwell hardness, and Vickers hardness.

HRB: 100 kg load and a hardened steel ball with a diameter of 1.5875mm used for materials with lower hardness. For example, mild steel, non-ferrous metals, annealed steel, etc.
