It is strong but can be magnetized radially or multi poles. Injection moulded bonded magnets can be formed together with other parts and have very strict tolerance on dimensions.
Various shapes of high dimensional accuracy can be produced without further processing. Surface is treated by epoxy coating or nickel-plating to prevent corrosion
