Note:

[1] The properties given above are typical at room temperature(23°C) for uncoated samples.
[2] Ring Crushing Strength K is defined as follows, with the force applying along a diameter of magnet ring and P is the value at which the first crack appears. K=P(D-T)/LT2
K—Ring Crushing Strength(kg/mm2), P—Load on magnet ring(kg), D—Outer diameter(mm),
T—Ring thickness(mm), L—Height of the ring(mm)
