Standard Programme of Permanent Magnets
The standard programme of permanent magnets consists of sintered neodymium magnets (NdFeB), sintered samarium cobalt magnets (SmCo) and ferrite magnets (SrFe).
The magnets can be supplied under favourable terms.
For information on types, dimensions, quantities, prices etc. please contact us.
Please notice: When ordering standard magnets, an extra fee of 2,500.- we will be added to cover start-up costs for drawings, technical clarification and administration.
Terms of payment after agreement.

Neodymium magnets are very brittle and must be handled with care. All are anisotropic (the magnet strength is strongest in one direction).
Alloys are available which increase maximum operating temperatures but at the expense of magnet strength. Please contact us for more information about this and custom sizes.
