Thai Thavorn Casting Lathe Co.,Ltd
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).
Silicons | Article about silicons by The Free Dictionary
The hardness of silicon on Mohs’ scale is 7.0; the Brinell hardness is 2.4 giganew-tons per m 2 (GN/m 2), or 240 kilograms-force per mm 2 (kgf/mm 2). The modulus of elasticity is 109 GN/m 2 (10,890 kgf/ mm 2 ); the coefficient of compressibility is 0.325 × 10 −6 cm 2 /kg.
Tungsten carbide is a non-oxide engineering ceramic. It has the highest density among non-oxide engineering ceramics. In addition, it has the highest fracture toughness and the lowest heat capacity. The graph bars on the material properties cards below compare

Silicon (Si) An essential alloying element in most steels. Added to increase solid-solution strength and hardness as well as to increase hardenability. Is added to molten steel to remove oxygen (deoxidize). As a result of deoxidation, can form silie carbide in
The larger the indent left in the surface of a workpiece (specimen) by the Brinell indenter with a defined ball diameter and a defined test force, the softer the tested material. In order to determine the Brinell hardness (HBW) according to ISO 6506, the spherical, hard metal (tungsten carbide) indenter is pressed into a specimen (workpiece) with a defined test load (between 1 kgf and 3000 kgf).

Mohs scale of mineral hardness - Wikipedia
The Mohs scale of mineral hardness (/ m oʊ z /) is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. Created in 1812 by German geologist and mineralogist Friedrich Mohs, it is one of several definitions of hardness in materials science, some of which are more quantitative.
SSiC is formed by bonding together the crystals of alpha silicon carbide (α-SiC), which form at very high temperatures. It’s hardness is second only to that of diamonds, and is highly resistant to granular abrasion. The high purity of our ceramics (>98% SiC) also
Tungsten Carbide (WC)
Tungsten carbide parts are typically comprised of a cemented carbide (also known as hardmetals) − individual WC grains iedded in a metal binder matrix of either cobalt or nickel. The toughness and hardness properties can conform to specific appliion requirements by adjusting the grain size of the tungsten carbide and/or the binder content.
