Magnetising & Testing
As a long standing manufacturer of permanent magnets, Bunting Berkhamsted has its own large magnetising facility which we can offer as a service for the magnetisation of customer’s products.
For the prototyping of new products we can build prototype fixtures capable of magnetising small volumes of samples or full production fixtures when volumes increase. Certain types of prototype fixture can be upgraded to production fixtures at a later stage to reduce cost.
All our production fixtures are water cooled and are automatically programmed to the run at the correct operating voltage by the magnet charger for quality control purposes. Certain magnets require to be magnetised with poles aligned with some feature on the magnets. The magnetising fixtures can be error proofed to guarantee the alignment of the poles.
The Quality Control Department also has an extensive range of magnetic testing equipment which is available for the testing of customer’s magnetic products.

Design Consultancy
For magnetic design Bunting Magnetics Europe operate both 2D and 3D Finite Element Analysis software, with a comprehensive library of magnetic material properties.
The software is compatible with most mechanical CAD packages so customers own designs can be directly imported. We also have the facilities to measure the BH curves of permanent magnets on site, so we can use real measured data in the calculations, both at room temperature and at elevated temperatures.
When applicable, magnetisation data which has been generated from the design of the magnetising fixture can be used to model the magnet. This is a very powerful tool and is particular important for the modelling isotropic magnets such as bonded NdFeB where the direction of magnetisation is defined by the magnetising fixture and can vary considerably throughout the magnet volume.

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

Neodymium Magnets
Neodymium Magnets are the strongest commercially available permanent magnets, also known as Neo, Neodymium Iron Boron, NdFeB or Sintered Neodymium. These rare earth magnets are manufactured in a wide range of shapes, sizes and grades. Generally plated with NiCuNi to protect from corrosion. Custom and standard sizes are available.
Neodymium magnets are the most powerful magnets available. They are the first choice for maximum performance from minimum size.
Full range of Neodymium Magnet Grades available.
Radially Aligned Magnets Available to replace Arcs.
2 rare earth magnets available; Neodymium magnets and Samarium Cobalt
Grain Boundary diffusion now available in commercial quantities
Neodymium magnets maximum recommended temperature ratings from +60°C up to +230 °C, depending on grade.
All Bunting Magnetic’s neodymium magnets are REACH and ROHS compliant and do not contain SVHC’s.
