Samarium Cobalt (Rare Earth) Magnets

Uses for Samarium Cobalt Magnets

These strong magnets are used in a variety of applications. Favoured for many specialist applications where temperature or corrosive environments are an issue. Many precision control systems in aircraft, marine and spacecraft use Samarium Cobalt Magnets due to their great temperature stability. As precision is a crucial element of these devices round magnets such as Samarium Cobalt discs are most commonly used. The magnetic field produced by Samarium Cobalt cylinders and discs is far more targeted then that created by a block shaped magnet. Samarium Cobalt disc magnets are also a preferred choice for industrial designers, manufacturers and craftspeople.

Samarium Cobalt Magnet properties:

Samarium Cobalt magnets are an alloy composed of SmCo5/Sm2Co17, produced by the powder metallurgical method. These magnets are extremely hard and brittle in nature. They have high demagnetisation resistance and excellent anti-corrosion properties. Samarium Cobalt also exhibits outstanding thermal stability. The limited availability of raw material supply results in a relatively high cost. Please feel free to contact our sales team if you require any further information.

FAQs

Samarium cobalt magnets vs neodymium magnets?

The most significant difference between Samarium cobalt magnets and Neodymium magnets is the magnetic strength. Neodymium magnets are by far the outperformers by this measure. However Samarium Cobalt magnets are far better placed to withstand high temperature or humid environments.

What are samarium cobalt magnets used for?

They are used as component parts in highly technical mechanical operations where heat or humidity are factors.

What is the samarium cobalt magnet temperature limit?

300 degrees Celsius. We do our best to include the relevant technical information on the product page for each magnet. We have further information available in our Knowledge Base including the temperature range for all forms of permanent magnets.

Who are samarium cobalt magnet suppliers?

AMF is Australia’s most trusted magnet supplier. Unlike many of our competitors we have continued to stock Samarium Cobalt magnets to ensure we have a diverse range of magnets available for our customers.
