The Advantages of permanent neodymium magnets :

High Performance:


High Performance: The high performance KST Magnets can reach: N54, 52M, 50H, 48SH, 42UH, 38EH, 33AH, etc.

High Consistency:


High Consistency: The Cpk of Remanence (Br) and Intrinsic Coercive Force (Hcj) are much higher than 1.67. The consistencyof the surface magnetic field and magnetic flux can be controlled at +/-1%.

High Working Temperature:


High Working Temperature: The magnets of KST can satisfy the working temperature requirements with excellent temperatureresistance. The AH series with 40 kOe super-high coercive force can replace Smco magnets in most applications.

High Anti-Corrosion:


High Anti-Corrosion: The perfect coating of KST Magnets can meet many anti-corrosion requirements. The salt spray testand humidity heat test of the high anti-corrosion coating Nickel+Copper+Epoxy is typically more than 1000 hours.

Low Weight Loss:


The super-high magnets of KST have a long lifetime with the following specifications; PCT: 130°C,humidity 100%,vaporpressure 2.7bar, 20days,average low weight loss <2 mg/cm2.

Magnetise Direction of permanent neodymium magnets :

They are always anisotropic which means that they can only be magnetised in preferential direction, axially and diametrically. But by using special coils, Neodymium magnets can be magnetised in a multipoled way.

Temperature of use is maximum 80°C to 240°C, depending on the specification, dimensions and system design.
