Simotec Neodymium Magnet
Manufacturer: Shimonishi Giken Kogyo Co., Ltd
Product name: Neodymium Magnet
Features
- Neodymium magnets are primarily compose of neodymium, iron, and boron, and have the best magnetic properties of any magnet currently available.
- Neodymium magnets are a representative rare earth magnet, and are characterize by their stronger adhesive power than other magnets.
- Even when make smaller, satisfactory suction power can obtain, so it can fully meet the demand for downsizing.
- While it has excellent mechanical strength, it is not suitable for high temperatures.
- – Because it is prone to rust, it is plate to prevent rust.
Purpose of use
・Motors, sensors, precision machinery, etc.
Specification
Neodymium magnet N35: Comparison of demagnetization curves due to temperature difference
N35H: Comparison of demagnetization curves due to temperature difference
N35SH: Comparison of demagnetization curves due to temperature difference
