NdFeB, which is also known as neodymium magnets, is combined of neodymium, iron, and boron. NdFeB is the strongest available and with widespread usage in electronic devices and equipment. It is basic requirement to understand the features and quality of NdFeB for selecting the optimal type for your application. You will obtain six insider tips for choosing the most suitable NdFeB magnet based on your requirement.
Tip 1: Know the properties of NdFeB magnets.
Understanding the features of NdFeB magnets is essential request for selecting. Magnetic and physical characteristics are the basics for performance and applicability of NdFeB magnets.
● What is Magnetic properties?
Magnet strength is measured by maximal energy product (BH) max, and NdFeB magnets may reach up to 52 MGOe (Mega-Gauss-Oersteds). Grades of NdFeB magnets is from N35 to N52, corresponding to increasing magnetic strengths. The more going up in quality, the stronger magnet is. NdFeB magnets’ coercivity and magnetic remanence are quite high to ensure the magnetic qualities be preserved as long time as possible.
● What is Physical Properties?
Besides magnetic properties, physical properties is also basics for NdFeB magnets. The physical properties include density, curie temperature, and thermal conductivity of the magnet.
Tip 2: Take the temperature range into account.
The operating temperature is crucial when selecting right NdFeB magnet. Temperature range for NdFeB is from 80°C to 200°C, depending on the magnet’s grade and coating types. In case you need a magnet to withstand extreme heat, then it is important to choose a magnet with high curie temperature and appropriate coating type that can tolerate the operational temperature range.
Tip 3: Analyzing the application requirements.
Examining your expectation by carefully reviewing the chosen NdFeB magnet’s application prerequisites that is based on the specifications of your specific application. When evaluating the needs of application, please consider the following points:
● Magnetic strength:
The purpose and conditions of your application will determine needed magnetic strength. N52-grade magnet is an excellent option for a strong magnetic field. In case a lesser magnetic field is needed, just choose magnet with N35-grade.
● Magnet shape and size:
In addition to the magnetic strength, the size and form of magnet are critical in determining with NdFeB magnet will perform best. Discs, blocks, rings and arcs are common form of the NdFeB magnet. The best performance of the magnet requires the size and shape correspond with the applications.
● Operating environment
Please consider the environment where the magnet will be utilized. The magnet may be exposed in corrosive or harmful circumstances, hence, it is critical to choose magnet with adequate coating.
Tip 4: Choose the right coating type.
NdTeB magnet must be suitably coated to avoid of wear and tear from outside environment due to its sensitivity to corrosion. The appropriate coating type is decided by working environment and application requirement. For NdFeB magnet, nickel, zinc, and epoxy are common coating types.
Tip 5: Magnetization direction
The magnetization direction must be considered too. The thickness, diameter, and length of NdFeB magnet are all possible magnetization axes. The magnetic strength and efficiency of the magnet might altered basing on the magnetization direction. This is the reason that matching your application’s requirements with the proper magnetization orientation is critical.
Tip 6: Quality matters
Selecting the right magnet for your application is also significantly influenced by the quality of NdFeB magnet. Low-quality magnets may last less working time or less perform as higher-quality ones. To ensure the quality and effectiveness of NdFeB magnet, please cooperate with reputable suppliers.
Final words:
It is crucial for selecting the appropriate NdFeB magnet by understanding the magnet’s qualities, application needs, operating environment and so on.
