Product Description
I. Anisotropic sintered Neodymium multipole rings
Neodymium 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. Sintered NdFeb canbe made in Arc, cylinder,ring and some irregular 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 manufacturing direction, 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 tolerances.
2) Delivered magnetized or unmagnetized? Magnetization direction?
3) Information on what you want to use the magnet for?
Wish our products will be helpful for your business.
