This is a custom-shaped segment magnet with a 3mm diameter countersunk hole, which is made of rare earth neodymium. The specific size is: The outer radius is 17.6mm, the inner radius is 9.9mm, the heigth is 30mm. The radian of contersunk hole is 45° and the diameter of center is 3mm. The single weight of this magnet is 16.51g, and the central surface magnetism is 3024 gauss. The sample is used Nickel plated and the surface color is silvery white. The working temperature generally is 150℃(neodymium usually work at 80℃,and can up to 200℃).
Countersunk arc magnet is not used alone, it is matched with other components together, combined or fixed the needed screws or other componebts to match together, can provide convenience when fixing work
