Solid alloys tungsten-cobalt

Solid alloys tungsten-cobalt

Supplier — AvekGlob company — offers at reasonable prices from the manufacturer solid alloys based on tungsten carbide and cobalt. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Technical specifications

Solid alloys are highly melting compounds of solid, ceramic tungsten carbide and viscous cobalt. These materials are 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. The cobalt content ranges from 1% to 30% by weight, depending on the application.

The main properties of these alloys — strength, hardness, high electrical and thermal conductivity, with low plasticity and resistance to bending.

Urgency of application

Hard alloys based on tungsten carbide and cobalt are used in the manufacture of extra-strong instrumental brushes by pressing and sintering methods. To increase strength and rigidity, surface coatings are used.

From the considered alloys also produce mountain and cutting tools, as well as wear-resistant parts of machines.

Chemical composition and physical and mechanical properties

In accordance with the technical requirements of GOST 3882−74, the most common solid alloys of the WC-Co system of domestic production have the following performance characteristics:
