Strong rare earth ring magnets, Ring Neodymium Magnets are strong rare earth rare earth magnets with a circular shape and a hollow center. Neodymium (also known as “Neo”, “NdFeb” or “NIB”) ring magnet is the most powerful magnet on the market today, and its magnetic properties far exceed other permanent magnet materials. Due to its high magnetic strength, neodymium ring magnets have replaced other magnetic materials in order to achieve the same results while reducing the design size.

Approximate pull information

The approximate pull information listed is for reference only. These values ​​are calculated on the premise that the magnet will be attached to a flat, ground 1/2 inch thick mild steel plate. Coatings, rust, rough surfaces and certain environmental conditions can significantly reduce tensile force. Please make sure to test. For critical applications, it is recommended to reduce the derating by 2 times or more according to the severity of the potential fault.

Manufacturing method

Our neodymium alloy discs are sintered to obtain the best magnetic strength and are magnetized in the axial direction (the direction of magnetization is along the axis of the magnet from north to south). Common finish options include unplated nickel, nickel (Ni-Cu-Ni) and gold (Ni-Cu-Ni-Au) plating.

Measurement tolerance

The standard tolerances for diameter and thickness dimensions are both +/- 0.005 inches.

NdFeB rod-shaped and SmCo Ring Magnets are commonly used in power generation equipment, high-performance motors, consumer electronics, magnetic sensors, high-end audio equipment, surgical instruments, and high-strength separation for industrial, medical, aerospace, automotive and commercial industries Device, and consumer use.
