Product Description
These bonded neodymium magnets are formed by pressing or injection moulded. They are 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.
They are usually used in precision machine or small motor. They are strong power but have good magnetization.
