VK10 plate, hard alloy
Supplier — AvekGlob Company — offers at reasonable prices from the manufacturer plates made of a solid alloy grade VK10 (other designation VK10-HOM). The supplier guarantees the timely delivery of products to any address specified by the consumer.
The hard alloy VK10 is a highly melting compound of solid, ceramic tungsten carbide with viscous cobalt. This material is a composite of a metal matrix in which cobalt particles are placed in a matrix of tungsten carbide. Tungsten carbide may have the formula WC or WC 2, depending on the synthesis conditions.
A characteristic feature of this alloy is high strength, compression and hardness resistance, high electrical and thermal conductivity, at sufficiently low values of plasticity, toughness and shear resistance. The alloy is distinguished by an average sensitivity to shear and bending stresses. It is made in two modifications — VK10 and VK10M (in the latter case, the strength and hardness are reduced, but the resistance to impact loads is increased).
Urgency of application
The VK10 grade alloy is used in the manufacture of particularly strong tooling by pressing and sintering methods. It is used for making both cutting and cold-setting tools. To increase strength and rigidity, surface coatings are used. The VK10 alloy can be used to manufacture a deforming tool with increased wear resistance, for example, banding matrices).
In accordance with the technical requirements of GOST 3882−74, the alloy VK10 has the following composition:
Tungsten carbide — 90%;
Cobalt — 10%.

Assortment and properties
The hard alloy VK10 is obtained by sintering the dimensions of the initial mold taking into account the shrinkage. Available plates, discs and cylinders of various sizes. It is possible to obtain plasticized plates, previously sintered at high temperature. To obtain the final product it is necessary to use the technologies of electric spark, electric-arc or anodic-mechanical treatment. Less effective grinding with carborundum circles, followed by grinding with powders of boron carbide.
