The first cemented carbide developed was tungsten carbide (introduced in 1927) which uses tungsten carbide particles held together by a cobalt metal binder. Since then, other cemented carbides have been developed, such as titanium carbide, which is better suited for cutting steel, and tantalum carbide, which is tougher than tungsten carbide. [1]
Ceratizit is a producer of cemented carbide products. The company manufactures cutting tools and products for wear protection, such as solid carbide tools and inserts, hard material rods, and wear parts, such as turning tools, drills, and milling cutters for private labels, distribution partners, and end consumers.
In 1974, the first carbide saw with a vertical slide was developed by Arno Willemeit, the co-inventor of the Braunschweig tooth geometry. [5] It was produced by the company Ohler in Remscheid, Germany. Framag, an Austrian company later took over the production of this type of machine and also built it as a layer saw.
Cementite (or iron carbide) is a compound of iron and carbon, more precisely an intermediate transition metal carbide with the formula Fe 3 C. By weight, it is 6.67% carbon and 93.3% iron. By weight, it is 6.67% carbon and 93.3% iron.
Karl Schröter used liquid-phase sintering to bond or "cement" Moissan's tungsten carbide particles with cobalt in 1923 in Germany. Cemented (metal-bonded) carbide edges greatly increase the durability of hardened steel cutting tools. W.H. Nernst developed cubic-stabilized zirconia in the 1920s in Berlin. This material is used as an oxygen ...
Element Six is a company specialised in providing synthetic diamond, cubic boron nitride and other superhard materials for industrial use. Part of the De Beers Group, Element Six employs over 1,900 people and its primary manufacturing sites are located in the UK, Ireland, Germany, South Africa, and the US.
Pramet's roots date to 1933 when the Stellwag company began production of cemented carbide and natural diamond tools. The Pramet organization was founded in 1951 in Šumperk , Czech Republic. [ 7 ] The company name is derived from the principle of the technology used to produce its products – powder metallurgy .
Treibacher Industrie AG is a manufacturer of chemical and metallurgical precursors for industrial applications. It produces ferrovanadium and ferromolybdenum for the steel and foundry industries, powders for the cemented carbide industry, and materials for ceramic applications, as well as fine chemicals for the pharmaceutical and catalyst industries.
