Ferrite Magnets' outstanding properties   

Br can reach 4300 GS Hcb can reach 3946 OE,

Hcj can reach 4147 OE (BH)max can reach 4.45 MG OE.


1) High performance:

JC-Y3932; JC-Y3939; JC-Y4041; JC-Y4127; JC-Y4231; JC-Y3744; JC-Y3849; JC-Y4240 JC-Y4350 etc (The grade like JC-Y4350&JC-Y3849, JC-Y4240could meet requirements on strong power).  

2) High working temperature: 

The JC-Y4350 series with 4800-5150 OE super-high coercive force can replace NdFeB magnets with much lower price. 

3) High consistency: 

The Br and Hcj of surface magnetic field and magnetic flux can be controlled with +/-1%. 

4) High Anti-corrosion: 

The sale spray test and humid heat test of the high anti-corrosion coating could be more than 800 hours

5) Low weight loss

The average low weight loss is less than 10 mg/cm2 in 20 days. 

Pros: Pretty strong hold between two of these blocks even if a couple of them by contacting the other one or plain iron. It's difficult to pull away them(easy to slide however). 


Ferrite Magnet Applications: 


Applicable for the starters of 1.0W, 1.2W. 1.4W, 1.5W, 1.7W are available and mainly applied in Nissan and Red Flag based on JC-Y3744, JU-Y3849 MATERIAL Grade and different requirements of environmental temperatures can be adapted to. 


In 2007, "Technological of manufacuturing high-performance ferrite permanent with YF30 pre-sintering materials" and "Technology of Preparing ferrite magnet for high-performance automobile strter motor with YF30 pre-sintering materials" were awarded with the file of Outstanding Technical Achievements and Outstanding products by the National Materials and Devices industry Assocuations.
