The magnetic extrusion is a strontium ferrite magnetic powder within a thermo-plastic binder that is extruded through a die to create a specific profile which is then magnetised multiple-pole on one surface.
.
The magnetic extrusion has one magnetic face and can be put against itself as pairs to magnetically attract to itself (self-mating). The maximum operating temperature of the magnetic extrusion is +80 degrees C – above this temperature the binder starts to soften causing the magnetism to fail as it de-magnetises as the magnetic domains re-align to cancel themselves out..
