Physical Properties and Application to Environment of the Coating

NdFeB Magnet Machining And Service:
· All kinds of shapes of magnets can be supplied after grinding, electric wire spark cutting, mechanical drilling and cutting, and other methods.
· All kinds of magnets with coating can be supplied, such as electric coating, electroplating and phosphorizing and so on. It is guaranteed that the product will have a good appearance and anti-corrosion characteristics.
· The magnet can be magnetized in single, multi and radial directions.
· According to the needs of customers, magnet can be aged, demagnetized, re-magnetized after demagnetization.
· The chemical compositions of raw materials and magnets can be analyzed by ICP. The magnet microstructure can be observed by microscope and magnetic powder size distribution measured by the Laser Particle Size Analyzer. The magnetic properties can be tested by means of B-H tester at both ambient and high temperatures.
· The coating layer can be analyzed by means of SST, PCT, HHT, dropping and layer thickness tester.
· The magnetic circuit analysis and design can be offered for customer.
· Magnets with special characteristics are also available at the request of customers.
