The advantages are anti-demagnetization and high cost performance.
Product Brand
The performance of this product is 35H.
The N series grades we can make are: N35, N38, N40, N42, N45, N48, N50, N52, N54.
Magnetic Performance Distribution Map
Surface Treatment
Sintered NdFeB permanent magnet material is a powder metallurgical material with strong chemical activity, its characteristics are hard and brittle, and it is easy to be oxidized and corroded. Based on this feature, the most effective method currently adopted is to coat the surface. The usual methods are blue and white zinc plating, color zinc, nickel copper nickel, chemical nickel, epoxy resin, phosphating and so on.
We can also perform surface treatments such as silver plating, gold plating, Everlube, etc. according to your requirements.
Sintered NdFeB Magnet Thickness standard of coating and lntroduction | ||||||
Nd-Fe-B substrate is easy to be corroded. In order to overcome this defect, the surface of Nd-Fe-B substrate is often coated with blue white zinc, color zinc, nickel copper nickel, electroless nickel, epoxy resin and phosphating. | ||||||

Note: 1. Pressure test conditions: 120℃ 100%RH*2.0ATM*48hrs Continuous High Voltage 2. Salt spray test conditions: 5%NACL,35℃ 48hrs Continuous spray 3. The time of salt spray test and PCT test for different products depends on the actual shape |
Reliability Test
The reliability tests we usually do are:
Test name |
Test conditions |
Plating Thickness |
The coating thickness was measured by X-ray thickness gauge |
PCT test |
No cracks, peeling, bulging, rust and other defects were found in the coating after 48 hours of testing at 120 ℃ / 100% RH / 2atm |
Salt spray test |
After continuous spraying for 48 hours at 35 C /5% NaCl solution, the coating is not blackened or rusted. |
Aging test |
Under 120 ℃ for 2 hours, the magnetic flux decay rate is less than or equal to 10% |
Tension test |
The shrinkage is less than 1 / 3 of the area in 3S |
Remarks: The above test conditions are formulated for most products. If you have anything else you need to know, our engineers will provide you with appropriate suggestions.
