Tungsten vs. Titanium and other metals: Using The Moh''s Scale Of Hardness Chart To Determine Scratch Resistance When it is time to shop for a man''s wedding band, it is time to start wondering how titanium stacks up against tungsten carbide. The Moh''s Scale
Black silicon carbide is brittle and sharp, and has high hardness, low expansion coefficient，good thermal conductivity and electrical conductivity. It takes petroleum coke and high quality silicon as raw materials, adds salt as additive, and is fused through the electric resistance furnace at high temperature. hexagonal crystalline of microscopic shape, 3300kg/mm³ of microhardness.
Tungsten Carbide has a high melting point, 2,870 C (5,200 F), is also extremely hard ( Vickers hardness nuer = 2242) and has a low electrical resistivity (~2×10−7 Ohm•m), compared to other metals (e.g. vanadium 2×10−7 Ohm•m). Rockwell Hardness
Silicon Carbides (SiC) exhibit characteristically high hardness, wear resistance, corrosion resistance, and strength — even at high temperatures. CoorsTek has engineered a variety of silicon carbide processes and compositions which deliver properties and features optimized for specific appliion requirements including:
Grains of Silicon Carbide are bonded together by sintering obtain hard ceramics. They are widely used in using Brinell hardness testing machine. By selecting the ball indenter diameter 5mm and major load 250kgs, test was conducted for the 5.4.4 Computer
Silicon Carbide Powder, Abrasives, Black Silicon Carbide While silicon carbide has lower hardness and abrasive capacity than diamond and boron carbide, it is widely used for grinding non-ferrous materials, finishing
Silicon Carbide – SiC Silicon carbide was discovered in 1893 as an industrial abrasive for grinding wheels and automotive brakes. About midway through the 20 th century, SiC wafer uses grew to include in LED technology. Since then, it has expanded into numerous
A chart is then used to convert the averaged diameter measurement to a Brinell hardness nuer. Test forces range from 500 to 3000 kgf. A Brinell hardness result measures the permanent width of indentation produced by a carbide indenter applied to a test

The hardness of Ductile Iron is usually and best measured by the Brinell test, in which a 10 mm diameter hardened steel or tungsten carbide ball is pressed into a flat surface of the workpiece. Hardness is expressed as a Brinell Indentation Diameter (BID) or a Brinell Hardness Nuer (BHN).
The hardness of alumina ceramics is nearly three times that of stainless steel; silicon carbide is more than four times harder than stainless steel. This extreme hardness is one of many unique properties that makes Fine Ceramics "super materials" for modern technology.
