Widia: what is it?<\/h1>
\"widia\"<\/figure>\r\n
Widia is a material with a very high degree of hardness. Also known as Cemented Carbide<\/strong> or Hard Metal<\/a>, it is mainly used in mechanical machining. <\/span><\/span><\/figure>\r\n
The term derives from the German wie Diamant or “hard as diamond”. In fact it is a very hard alloy, obtained by adding tungsten carbide to a cementing metal such as cobalt. It was the German Krupp who registered the trade name Widia and first used the material as a cutting tool in 1927. <\/span><\/span><\/figure>\r\n

Features of Widia<\/h2>\r\n
The characteristics of Widia are hardness<\/strong> and high density. In other words, the material is resistant to abrasion, pressure and deformation. Also, it resists corrosion, erosion, metallic seizure and high temperatures. In short, Widia components and tools are not subject to wear. They are harder than steel ones. And they withstand the highest cutting temperatures. <\/span><\/span><\/figure>\r\n

\u00a0The Widia <\/span><\/span>Production<\/span><\/span><\/h2>\r\n
production process is called sintering. What’s it about? First of all the carbide, tungsten and cobalt powders are mixed. Then they are pressed and exposed to high temperatures. As a result, the tungsten carbide particles are incorporated into a cobalt metal matrix. Up to form a single block. With Widia, hard metal producers can achieve: Exclusive products such as<\/span><\/span> gears,<\/span><\/span> machining tools or mechanical components. <\/span><\/span><\/figure>\r\n
Semi-finished products such as widia bars, cylinders and rough inserts, which will then be processed to make tools and tools in hard metal. <\/span><\/span><\/figure>\r\n
Thanks to grinding with diamond wheels<\/strong> or diamond pastes for sanding, the hard metal is refined. Thus it obtains the desired shape, size and type of surface. Types of use of Widia A material such as Widia is resistant and of considerable hardness. Therefore it meets the needs of multiple industrial applications. Among other things, it is used in the following industrial sectors: <\/span><\/span><\/figure>\r\n
