I. Anisotropic sintered Neodymium multipole ringsNeodymium magnet is mainly made of Neodymium, Iron and Boron. Neodymium magnet is offered in range of operation tem 80ºC to 220ºC. A sintered Neo magnet has high remanence, high coercive force, and is easily formed into various sizes and shapes. The magnet is suitable for being used in DC Motor, Brushless motor , Speaker, MRI and others.II. Features :
Since NdFeB magnets easily corrode, it is often coated to protect against this. Traditional coatings are Nickel, Zinc, and Epoxy with other options available. Selection of a coating should be discussed early on in the design and application process.SinteredNdFeb canbe made in Arc, cylinder,ring and someirregular shape.

VII: Description:1.Q:Why we focus on producing ring magnet?
A:Because it's more stable than magnetic tile which used in motor.
2.Q:What's the mean of Anisotropic?
A:Anisotropic ferrite magnets are different, they are all oriented in the manufacturingdirection, and should be magnetized in the direction of orientation.
3.Q:Magnetizing direction?
A:At your request.VIII. Buyer Guide:We will help you with your order. Usually we ask for the following information.
1)Product material,size, grade, coating, quantities required. etc..if available, a sketch or drawing with dimensions and toAssembly Line & Production Line lerances.
2) Delivered magnetized or unmagnetized? Magnetization direction?
3) Information onEngineering & Construction Machinery what you want to use the magnet for?Wish our products will be helpful for your business.
