Magnets

Neodymium is the highest strength magnet material available. It is very brittle and usually coated or contained in an assembly (see below) because of this and poor corrosion resistance.

• High power
• Low maximum temperature 100 degrees C (although alloys can made that operate up to 180 degrees C)
• Poor corrosion resistance
• Very brittle

Ferrite is the most widely used magnet material. Also know as 'ceramic'.

• Operate at lower temperatures than cast alnico magnets - up to 250 degrees C maximum.
• Economical
• High coercivity - do not lose their magnetic properties easily
• Hard and brittle

A family of materials based on the same mix of elements (Aluminium, Nickel, Cobalt).

• High maximum temperature - up to 550 degrees C.
• Economical
• Very stable
• Good corrosion resistance

Most suitable materials for custom products (can be cast in a range of shapes and magnetic properties can be altered)

Magnet material contained in a housing. This is done to protect the material, change the properties of the magnet, allow magnets to have fitment such as screw threads or hooks.

Includes pot magnets, which provide more powerful clamping than equivalent round magnets, hook magnets for signage and magnets with threads or holes for easy attachment

Strontium ferrite magnet material is loaded into a thermo-plastic which is then extruded into strips or calendered into sheets.

Self adhesive coatings or coloured vinyls are added to the non-magnetic face as required.
