WOCO tungsten carbide : What is the difference between …
In conclusion, there are some difference between tungsten carbide and solid carbide. T ungsten carbide cutting blades is made of solid carbide, but if this cutting tool is solid carbide , that is saying that this cutting tool is very good quality, and long life span, bec ause some of the cutting tools have only carbide tips. not whole body made of carbide.

Rockwell scale - WikiMili, The Free Encyclopedia
The chief advantage of Rockwell hardness is its ability to display hardness values directly, thus obviating tedious calculations involved in other hardness measurement techniques. The equation for Rockwell Hardness is H R = N − d s {\displaystyle HR=N-{\frac {d}{s}}} , where d is the depth (from the zero load point), and N and s are scale factors that depend on the scale of the test being
Hardness of Steels - Brinell, Rockwell, Vickers
The test provides numerical results to quantify the hardness of a material, which is expressed by the Brinell hardness nuer – HB. The Brinell hardness nuer is designated by the most commonly used test standards (ASTM E10-14[2] and ISO 6506–1:2005) as HBW (H from hardness, B from brinell and W from the material of the indenter, tungsten (wolfram) carbide).
Hardness Conversion Chart, Calculator & Tests for …
The Brinell Hardness Test consists of indenting the test material with a 10mm diameter hardened steel or carbide ball subjected to a load of 3000 kg. For softer materials, there are alternate scales using a 1500 kg or 500 kg load to avoid excessive indentation.
