Tungsten carbide is a chemical compound containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through sintering for use in industrial machinery, cutting tools, chisels, abrasives, armor-piercing shells and jewelry.
Tungsten carbide is approximately twice as stiff as steel, with a Young's modulus of approximately 530–700 GPa,and is double the density of steel—nearly the same as gold.
Colloquially among workers in various industries (such as machining), tungsten carbide is often simply called carbide. Historically referred to as Wolfram, Wolf Rahm, wolframite ore was then later carburized and cemented with a binder creating a composite now called "tungsten carbide". Tungsten is Swedish for "heavy stone".
Sintered tungsten carbide–cobalt cutting tools are very abrasion resistant and can also withstand higher temperatures than standard high-speed steel (HSS) tools. Carbide cutting surfaces are often used for machining tough materials such as carbon steel or stainless steel, and in applications where steel tools would wear quickly, such as high-quantity and high-precision production. Because carbide tools maintain a sharp cutting edge better than steel tools, they generally produce a better finish on parts, and their temperature resistance allows faster machining. The material is usually called cemented carbide, solid carbide, hardmetal or tungsten-carbide cobalt. It is a metal matrix composite, where tungsten carbide particles are the aggregate, and metallic cobalt serves as the matrix.
Passion Tool supplies various products for corrugated Paper Board industry such as razor slitting blades, grinding stones, cross cutting blades and paper cutting blades. We specialize in powder metallurgy and apply to the production of carbide tools. Since its inception, we have carried out the company mission of "Never accept defective products". After nearly 20 years of development, Chengdu Passion has become one of the leaders in the national corrugated knife industry.
Being one of the renowned manufacturers and suppliers, We are engaged in offering a wide range of Industrial Blade. Our Industrial Blades are extensively acclaimed for acute sharpness and excellent finish. The entire Industrial Blades offered by us are manufactured using premium quality components and extensively acclaimed for durability and high performance.
The long-term cooperation with many well-known overseas and domestic corrugated cardboard enterprises is witnessed Passion tool’s advanced techniques.
We use high-quality tungsten carbide raw material, we specialize in the production of tools by powder metallurgy process. We press the powder and then sinter it in a vacuum furnace to form the knife blanks. This is the initial shape of the tungsten steel knife, and it takes more than a dozen processes to become a precision knife.
In the knife revolution, knife manufacturers play an important role. They follow the progress of material science, update the knife manufacturing method, and interact with the market.
