Ferrite Magnet
Ferrite Magnet is using SrO and Fe2O3 as raw material, through ceramic processes. As an important part of magnetic materials, permanent materials play a heavy role in electronic industry, IT industry, oil energy industry, mining and metallurgy, industrial automation and civil industry .
DATOYO also supply special Pump Magnets with multipole magnetized, they are widely used on Dishwasher, Washing Machine, DC Motor, Water Pump Motor (Rotor), Water Flow Sensing/Sensor, Car Fan/Oil Pump Motor, Speed Control Motor, Car Steering Headlight Motor.
