Tungsten Carbide Cutting Tools Properties

Tungsten carbide is one of the best metals that have been found to withstand excessive forces that cause impact damages.

Tungsten carbide cutting tools properties.

However it lacks sufficient toughness which is an essential property for cutting tools. Cemented carbides commonly use tungsten carbide titanium carbide or tantalum carbide as the aggregate. Carbide tool does not lose their hardness up to 1000 c. Tungsten carbide wc itself has a very high hardness beyond corundum or alumina and its hardness is rarely reduced as the operating temperature increases.

Tungsten carbide wc one of the most widely used cutting tool material in modern machine shops. They can withstand very high speed cutting operation. Strength tungsten carbide has very high strength for a material so hard and rigid. It consists of tungsten tantalum and titanium carbide with cobalt as a binder when the binder is nickel or molybdenum then it is called cermet.

Carbide cutting surfaces are often used for machining through 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. Titanium carbide tic and tungsten carbide are important industrially and are used to coat metals in cutting tools. It consists of fine particles of carbide cemented into a composite by a binder metal. Most of the time carbide cutters will leave a better surface finish on the p.

Therefore with tungsten carbide hardfacing your cutter tools will have better hardness and strength properties. Sintered tungsten carbide cobalt cutting tools are very abrasion resistant and can also withstand higher temperatures than standard high speed steel hss tools. Providing an ultrafine stoichiometric tungsten carbide powder with a specific surface area of more than 4 m 2 g and a non oxide purity of equal to or better than 99 9. Other materials such as titanium carbide tantalum carbide and niobium carbide are added to improve the properties of the material when cutting.

And providing a vacuum or inert atmosphere during the. Some exhibit a range of stoichiometries being a non stoichiometric mixture of various carbides arising due to crystal defects. Due to its high wear resistance characteristic it is applied in many applications that includes metal cutting mining wear parts x ray tubes. Mentions of carbide or tungsten carbide in industrial contexts usually refer to these cemented composites.

Cemented carbide tools are extremely hard. Some of them e g. These carbides have metallic properties and are refractory.

Without these additives when cutting ferrous materials the tungsten carbide tool may experience a chemical reaction between the tool and the chips of the work piece that leaves craters in the tool especially at high cutting speeds. A binderless high purity tungsten carbide cutting tool material made by a sintering procedure comprising the steps of.
