We carry a vast inventory of standard products in nearly every applicable grade of carbide for the woodworking industry. Chances are we have what you need in our catalog and on our shelves, and if not, we will custom manufacture to your specifications.  Tungsten Carbide DiesCarbide dies are a cheaper alternative to diamond and PCD dies and are often used for drawing wires from tough materials, such as carbon steel or stainless steel. Sometimes, tungsten carbide will leave a better finish on parts of a wire. We manufacture carbide dies in different shapes, like triangular, square, trapezium, hexagonal, octagonal, semicircle, stripped, flat, etc. Tungsten carbide dies are less expensive, but wear out quickly and loose size, therefore giving a shorter die life.

Tungsten Carbide ProductsIt is a ceramic material composed of approximately a 1:1 ratio of tungsten and carbon atoms. For practical applications it is alloyed with >6% of a softer metal, usually cobalt.
The primary attraction is its high strength and low ductility at high temperatures. Other important properties include thermal and electrical conductivity.
 Tungsten Carbide GradeIt is very good materials with high hardness, and good wear resistance and is widely used in the mining, petroleum, machining and steel industry as mining drill bits , cutting tools and so on. We can supply parts according to the users drawing and demand. |

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. We specialize in custom preforms. Tungsten carbide products are classified into three major categories:
• Wear Grades — used primarily in dies, machine and tool guides, and in everyday items such as line guides on fishing rods and reels. Used anywhere good wear resistance is required.
• Impact Grades — also used for dies, particularly for stamping and forming, and in tools such as mining drill heads.
• Cutting Tool Grades — the cutting tool grades of tungsten carbides are divided into two groups, depending on their primary application. If the carbide is intended for use on cast iron that is a nonductile material, it is graded as a cast iron carbide. If it is to be used to cut steel, a ductile material, it is graded as a steel grade tungsten carbide.
Cast iron carbides must be more resistant to abrasive wear. Steel carbides require more resistance to cratering and heat. The tool wear characteristics of various metals are different, thereby requiring different tool properties. The high abrasiveness of cast iron causes mainly edge wear to the tool.
Though tungsten demand is persistently growing owing to rapid development in national defense, civil and war industries throughout the globe, increase in supply shortage has become a major growth dampener for the distinctive metal. The growth of the tungsten market depends largely on new discoveries and explorations.
As cemented tungsten carbide is satisfying changing technical demands in milling and turning operations, it is considered a key material for cutting-tool inserts. Ceramic-metallic compounds and ceramics are being produced and used as replacements for cemented tungsten carbide in order to fulfill varying market demands. Demand for more distinctive metal, tungsten, is persistently growing owing to rapid development in national defense, civil and war industries throughout the globe. Tungsten carbide manufacture involves a complex sequence of operation, unique to this industry, in which almost every factor is critical to success. The original, and still the basic, product consists of fine tungsten carbide particles-the hard and abrasion-resistant constituent-bonded with tough, comparatively soft, metallic cobalt. Tungsten carbide can be supplemented or substituted by other hard constituents, such as the carbides or nitrides of other refractory metal, typically titanium, tantalum, niobium, chromium, vanadium, molybdenum or hafnium, independently or in combination, whilst the cobalt may similarly be alloyed with, or substituted by, nickel, nickel-molybdenum or similar metallic elements. The sintered product has often been compared to bricks or mortar, the comparison being true to the extent that the mortar (cobalt) is liquid during the final sintering and set solidly on being cooled from the sintering temperature. However, carbide is very much harder than brick and cobalt substantially tougher than mortar. Typical stages of manufacture are: .Production of tungsten metal powder (tungsten ore refine to tungsten metal). Preparation of tungsten carbide (the progression from tungsten powder to tungsten monocarbide WC_generally termed tungsten carbide) .Preparation of alloyed and other carbides (mix many kinds of metal according to certain proportion) .Admixture of cobalt to Produce grade powders Nov 2010 hot sold products:
