Non-magnetic tungsten alloy products: excellent performance, wide range of applications

Non-magnetic Cemented Carbide is non-magnetic mainly because its composition avoids the involvement of ferromagnetic elements, making it magnetically non-magnetic or very weakly magnetic. Conventional cemented carbides use cobalt as the binding metal, which is ferromagnetic. Non-magnetic Cemented Carbide avoids the source of ferromagnetism by instead replacing cobalt with a non-magnetic metal such as nickel or copper.

Even if small amounts of potentially magnetic components are used, the overall magnetic properties are reduced by controlling the proportions so that the magnetic properties of these components cancel each other out.

Non-magnetic Cemented Carbide is used in a wide range of scenarios where magnetic interference needs to be avoided, such as geological exploration, medical devices, and electronics. Materials are designed specifically to address these needs and maximize magnetic suppression.

For example, in logging and measurement with drilling (MWD, LWD) equipment, non-magnetic Cemented Carbide avoids magnetic interference and ensures accurate geological data collection. Common products include drill collars, stabilizers and anti-friction sleeves. Non-magnetic alloys are also used in surgical instruments and imaging equipment components.
