Samarium Cobalt Magnets
Samarium Cobalt Magnets or SmCo Magnets are rare earth magnets that offer high magnetic performance. Although they are not as powerful as Neodymium magnets, SmCo magnets start to outperform NdFeB magnets at around 150 to 180C. They are a very stable magnet and offer good corrosion resistance, so are particularly suited to military, aerospace, marine, automotive and other high stress applications.
Latest High Grades available now.
SmCo Magnets can be used in high temperature applications, typically up to 350C.
Start to outperform Neodymium magnets at temperatures above 150C.
High Tolerances can be achieved.
Very good corrosion resistance.
Can be coated for specific automotive and marine applications.
All Manufactured at ISO9001, ISO14001 and TS16949 accredited audited partners.
Certificates of Conformity, MSDS and PPAP’s available.
New XGS33 grade of Samarium Cobalt for higher stability and magnetic performance at raised temperatures;
Samarium Cobalt Magnets can be made in blocks, discs, rings, arcs, spheres, triangles, trapezoids and many other shapes. Please call or contact us for your specific requirements or for any technical assistance. Rapid prototyping and UK stock holding for Kanban / JIT deliveries is available. All customer specific magnets are inspected at our UK magnetic inspection facility. For full details of our capabilities visit: bunting-berkhamsted.com/magnets-experts

Other Products and Services from Magnet Applications
Grain Boundary Diffused Magnets
Grain Boundary Diffused (GBD) Neodymium magnets are the most powerful magnets currently available. They are the premium choice for maximum performance.
Grain Boundary Diffused magnets employ a secondary manufacturing process to concentrate the Heavy Rare Earth Element Dysprosium into the grain boundaries of the magnet microstructure, hence the name. This not only nets a performance increase but uses less Dysprosium making them more price stable than traditional method magnets.
All GBD Neodymium NdFeB is REACH and ROHS compliant and does not contain SVHC’s whilst licensed grades are produced to ISO9001 and ISO14001 Quality Control Standards. Certificates of Conformity, MSDS and PPAP’s can be supplied on request.
GBD Neodymium grades exist with the maximum recommended temperature ratings - from +60°C up to +230 °C but these ratings are GUIDELINE values only. The actual maximum temperature rating depends on the shape of the magnet and the design of the application. GBD magnets are limited in thickness to 8mm, and certain grades are not available with some magnet geometries.

Free Fall Metal Detectors
Gravity free-fall style metal separators and metal detector are designed specifically to isolate and separate any contaminated material moving in the product flow. They do this as the metal detector automatically picks up all kinds of metals, both ferrous and non-ferrous from the product flow and it is all conducted without any interruption to the line process.
Alnico Magnets
Alnico Magnets are extremely resistant to heat and corrosion and can operate at temperatures up to 500C. While Alnico magnets have very high Br values, comparable with NdFeB and SmCo they are easily demagnetised by external fields, but careful design can minimise this. We can help advise how to minimise these issues. With correct designing, Alnico can be a very powerful magnet with a superb temperature characteristic that no other magnet can match. It can also be used for applications where fine tuning is advantageous.
Full range of sintered and cast Alnico magnets available
Alnico is especially suited to customer specific or bespoke complex shapes and sizes
Alnico is suited to anything requiring high field output and operation at really high temperatures. Up to 500C.
High Magnetic Performance due to High Br Values - although low coercivity.
High Corrosion resistance.
Alnico is easy to “tune”. Which is important in some applications e.g. spectrometers and other specialist testing equipment.
Typically used in sensors, generators, loudspeakers, electric meters and even dc motors.
Can be ground to very tight tolerances.
