NdFeB Rubber
Overview
We strive to meet various customer needs by providing stable products through our consultation specialists, various suppliers and strict quality control.
NdFeB Rubber is Nd rubber magnet with soft material property as synthetic resins have been added to raw material. It can be easily cut and shaped with a knife or scissors since strong Nd magnet has been made into a flexible rubber magnet form. According to grade, it is manufactured in the range of 1.5-8.5MGOe.
Characteristics
It has similar magnetic characteristic value as that of bonded NdFeB magnet.
While having a high magnetic power with superior shape processing capability, its high price is its disadvantage.
The maximum temperature range is 100-120℃.
In addition to being frequently used for motor and speakers, it is also widely used for urgent mock up production for replacing bonded NdFeB because of its high processing capability.

NdFeB
Overview
We have become a reliable company with various testing equipment and quality control facilities as we strive to meet various customer needs by providing stable products through our consultation specialists, various suppliers and strict quality control. Neodymium magnet consists of Nd. Fe and B as main materials and it is named after the most important material. Contents of raw material vary by grade of magnet, and high grade uses heavy rare earth (Td, Dy and Yb). Magnet price is unstable because it is highly affected by raw material price of rare earth metal.
Characteristics
Among commercially available permanent magnets, it has the strongest magnetic force. Surface treatment is generally used to make up for its disadvantage of low stability against temperature and oxidation. Although general grade has low stability against temperature, high grade can be used in temperatures up to 220℃. Since it is stable against external magnetic field and maintains high magnetic force, it is used for a very extensive range of purposes. It is most commonly used magnet along with sintered ferrite magnet used for motor, sensor, speakers, toy, metal detector, high-strength adhesive/attachment parts, as well as for simple attachment and packing material purposes. Its precision degree and shape can be controlled depending on the magnet grade and processing method.
