Tungsten carbide button introduction

Tungsten carbide buttons are widely applied in geological prospecting, coal mining and oil well boring. Because of its wear resistance and hardness (9.8 Moe's scale), tungsten carbide is ideally suited for wear parts, other machine parts and dies which are subject to severe service conditions, such as high temperatures, corrosion and abrasion. In recent years, tungsten carbide has emerged as a superior alternative to steel in many industrial applications.

Most of this tungsten carbide wear parts and the mining tools are made of straight WC-Co hard metals without any addition of other carbides. Fine and ultrafine grained WC hard metals have become more and more important today in the field of wear parts, tools for chipless forming and cutting tools for cast iron, non ferrous alloys and wood.

A large portion of the tungsten volume in cemented carbide is today used in wear part applications, where there is a wide range of products from the very small (such as balls for ball-point pens) to large and heavy products, such as punches, dies or hot rolls for rolling mills in the steel industry.

Properties of tungsten carbide button

1. Cemented carbide/tungsten/spherical button
2. Wearing resistance good
3. Best suited to hard rock
4. Abrasive to very abrasive
