Tungsten Carbide has a hardness close to diamond. This makes it a commonly used material for applications requiring high strength and wear resistance.  Other tungsten carbide properties include:high fracture strength, high thermal conductivity, high resistance to thermal creep, high electrical conductivity, high resistance to corrosion, high modulus of elasticity Tungsten carbide is harder than sapphire and retains a superior edge after extensive use. It is not a metal alloy but the product of powder metallurgy; very fine grains of two materials are mixed and fused under high temperature and pressure. The hardness of T.C contributes greatly to its durability when sectioning. Durability depends on many factors including types of sample being cut, frequency of use and care taken in handling the blades. Thin sectioning ability - Because of the nature of T.C, there is a minimum section thickness that can be obtained. At grain boundaries the edge is microscopically discontinuous. The size of these discontinuities makes smooth sections below 1µm seemingly impossible as in these thinnest of sections minor knife marks are more apparent. Since contrast in sections below 1µm is very low, thicker sections are preferred for most light microscopy applications. Embedding materials - Tissues are usually embedded in plastic resins like Histocryl, LR White, and Spurr’s, glycol-methacrylate or methyl-methacrylate. Resins do not diminish blade life. Curiously, wax is destructive to these extremely hard edges. It seems that wax can pluck particles from the very fine edge and, however soft the wax, it quickly blunts a tungsten carbide edge. A tungsten carbide is a requirement for sectioning very hard or tough materials. Tungsten Carbide blades increase productivity on softer specimens, because of the time saving achieved by eliminating frequent changes of disposable steel blades, glass knives or sharpening of steel knives and also the elimination of frequent alignment procedures and the material cost of other knives. Tungsten carbide blades can last for thousands of sections each.We produce a broad range of T.C preforms & blanks that are used for wear, cutting & metal-forming operations in a variety of industries around the world. Custom tungsten carbide formulations are made with nickel and chrome binders for corrosive applications.
