Product Description
Flexible magnets are made by mixing ferrite or NdFeB magnetic powder with synthetic rubber or plastic through a specific process. Flexible magnets can be bent and twisted without damaging or reducing their magnetic properties, and they also have good machinability, allowing users to cut and punch with traditional tools.
NdFeB flexible rubber magnets have stronger suction than ferrite flexible rubber magnets.
