    Application of the countersunk magnet:
    Countersunk Magnets

    Advantages of strong countersunk magnets:
    1. High Grade / High performance:
    GME highest grade: N54, 52M, 50H, 48SH, 42UH, 38EH, 33AH, etc.
    Countersunk Magnets

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

    3. High Working Temperature:
    GME strong countersunk magnets can satisfy the working temperature requirements with excellent temperature resistance. 
    The AH series with 40 kOe super-high coercive force can replace Smco magnets in most applications.
