Cemented Carbide Ring for Industrial Wear Parts and Tungsten Carbide Applications

Cemented Carbide Ring Overview

Cemented carbide ring, commonly known as tungsten carbide or simply carbide, is a composite material consisting of hard carbide particles (primarily tungsten carbide, WC) bonded together by a metallic binder (usually cobalt, Co).

This combination results in cutting tools that are exceptionally hard, wear-resistant, and capable of operating at high temperatures and speeds.

It is widely used as an industrial wear-resistant and precision component.

Material Structure

Cemented carbide is a composite material consisting of:

Hard Phase: Primarily Tungsten Carbide (WC) grains, which provide the hardness.

Binder Phase: Typically Cobalt (Co), though Nickel or Iron are sometimes used.

This structure “cements” the hard grains together, providing toughness and preventing brittleness.

Key Properties

Hardness: Typically ranges from 1200 to 2000 HV, far exceeding hardened tool steel.

Density: Very high (approx. 14.5 g/cm³), giving a heavy and solid structure.

Thermal Stability: Maintains performance up to 800°C.

Elastic Modulus: About 2–3 times stiffer than steel, reducing deformation under load.
