DailyMag N55 Magnets
The strength of neodymium or rare earth magnets is measured on a scale of 24MGOe to 55MGOe. And compared to other grades, magnets in N55 grade are the strongest. N55 magnets are used for applications requiring high magnetic force in small or limited spaces. As an example, they are used in tight situations such as magnetic switches, sensors, and many more.
At DailyMag, we offer high-performance and cost-effective N55 magnets without sacrificing quality. Our N55 magnets are available in a variety of sizes and shapes such as blocks, discs, rods, and many more. We can provide the best N55 magnet solution that fits your budget, application, standards, and production schedule.
You can contact us for more information about our N55 neodymium magnets.
Applications
N55-grade magnets are commonly used in applications that have limited space but needs maximum magnetic strength. They are ideal for applications were small size is really important. For example, they can be used for holding securely something to its surface. Also, they can be used in tight situations such as magnetic switches, magnetic sensors, other delicate and fine applications.
N55 Magnet Production
N55 magnets and other grades have differences in terms of production. Because neodymium helps more to the rise of Br than praseodymium does, we are using pure (Nd) neodymium metal to make NdFeB alloy rather than praseodymium-neodymium (PrNd) alloy. Therefore, there is a significant price difference between the N55 and the N52 magnets.
Various Industries
N55 magnets are widely used in many industries such as:
- Electronics
- Medical
- Biotechnology
- Military and defense
- Automotive
- Space or aerospace
- Other industries
N55 Magnet Characteristics
N55 magnets are a type of neodymium or rare earth magnet. Neodymium, iron, and boron are the primary elements of neodymium magnets. They have characteristics such as:
- excellent resistance to demagnetization
- remarkable strength
- most powerful
- maximum operating temperature of about 80°C
- residual flux density of about 14.6 kgs. to 15.2 kgs.
Most Powerful N Series
In the N or neodymium magnet series, magnets in the grade “N55” are the most powerful. Previously, N52 magnets are considered the strongest and most powerful magnets. But compared to N52 magnets, N55 magnets are stronger at about 5 to 6%. The higher the neodymium magnet’s grade, the stronger the neodymium magnet. That’s why they are known as the most powerful magnets.
Thanks to the miniaturization process, N55-grade magnets can achieve the holding strengths that bigger magnets possessed, even if they are smaller. Due to their intense power, they are used for applications that need the largest amount of magnetic strength.
