 Frequently Asked Questions (FAQ) About Neodymium Block Magnets

1. What are Neodymium Iron Boron Magnets?

Neodymium Iron Boron (NdFeB) magnets, also known as Neodymium Block Magnets or NIB Magnets, are a type of rare-earth magnet renowned for their exceptional magnetic properties, including high Maximum Energy Product (BHmax) and strong coercive force. As critical components in energy-saving and green technology applications, NdFeB magnets are widely used in motors, generators, elevators, sensors, magnetic separators, MRI systems, voice coil motors (VCM), DVDs, mobile phones, printers, instruments, and household appliances.

2. How to Order Neodymium Block Magnets?

To ensure you receive the most suitable NdFeB magnets for your application, please provide the following information when placing an order:

Dimensions and Tolerances: A detailed drawing or specifications of the magnet’s shape, dimensions, and tolerances.

Magnet Grade: The specific NdFeB grade or magnetic properties required (e.g., N35, N52, or refer to our grade list). Lower-cost grades like N25 or N28 are available for budget-conscious applications.

Magnetization Direction: Specify the direction of magnetization or whether the magnets should be delivered magnetized or unmagnetized.

Additional Requirements: Details such as coating type (e.g., NiCuNi, Zinc, Epoxy) and maximum working temperature.

Quantity and Delivery: The required quantity and preferred delivery method (air or sea shipment).

Delivery Location: The nearest seaport or airport to your company for efficient logistics.
