Plastic-bonded neodymium magnets

Detailed product description

Plastic bonded neodymium magnets can be manufactured by means of pressing or extruding from basic material consisting of neodymium, supplemented with a binding compound, such as nylon/polyamide. The advantage is that it can be pressed or extruded in complex forms.

Plastic bonded neodymium magnets have a great resistance against corrosion, but it is still advisable to provide them with a coating so that the durability is optimal. Due to the isotropy, the plastic bonded magnets can be magnetized in different directions.
