What exactly is neodymium magnetic material? Neodymium is a rare earth metal with a high iron content. Boron is used as a bonding agent since neodymium is prone to corrosion. Neodymium magnets are utilized in a variety of applications such as remanufacturing, magnetic storage, and permanent magnets.
Neodymium magnet N42
A Neodymium magnet N42 has extraordinarily strong properties, making it an excellent option for a wide range of applications. They are an extremely powerful magnet with a draw force of up to one pound and measure little over a tenth of an inch in diameter. Standard and nickel-plated neodymium magnets are also available. Nickel-plated versions are made of a neodymium, iron, and boron alloy. Their nickel-plated finish is applied electrolytically, providing excellent corrosion resistance.
The suffix letter is another typical technique to identify a Neodymium magnet. These letters are associated with its temperature rating and are often an indicator of its inherent coercivity. Higher coercivity implies a higher temperature before irreversible losses in the output are seen. N42 neodymium magnets are available in a variety of grades, each matching to a specific use. Neodymium magnets, as you can see, exist in a variety of forms, sizes, and sorts.
Neodymium magnets come in a variety of grades, including N50, N52, and N42H. This grade strikes a fair mix between price and strength, and it performs well below 80 degrees Fahrenheit. Higher grades are more powerful, but they are also more expensive. For various uses, neodymium magnets come in round and rectangular shapes. You may also customize the size and form by selecting the right neodymium magnet N42 grade.
You're in luck if you're looking to buy a Neodymium disc magnet. The N42 Neodymium disc magnet from Applied Magnets is 10 times stronger than ceramic or steel. Its three layer coating resists demagnetization and ensures that it will never lose magnetism when utilized in close proximity to other magnets. Furthermore, their lengthy flat surface and triple-coating make them very robust, even under intensive usage.
The most popular kind of neodymium magnet is rare earth neodymium magnet. They are found in electric vehicle motors, DVD players, and hybrid vehicle wheels. The operating temperature and corrosion resistance of the application are often used to determine whether neodymium or samarium cobalt should be used. As a result, they are an excellent alternative for cars and other applications requiring high magnetic holding force.
The maximal energy product of a grade N42 neodymium magnet is 42 MGOe. The BH-curve and demagnetization curve of a magnet reveal its maximum magnetic energy, or (BH)max. The stronger the magnet, the higher the grade. N35 is the lowest grade of neodymium, while N55 is the highest. It is vital to realize that not all magnets are created equal, with some being superior than others.
The maximum operating temperature of neodymium magnets must be monitored. At significantly lower temperatures, a neodymium magnet rated for a maximum temperature of 150 degrees C may demagnetize and lose its magnetic virtue. A magnet rated for a maximum temperature of 80 degrees Celsius is unlikely to be adequate for these applications. The neodymium magnet N42 is very powerful, which means it may harm electrical equipment and even the shadow mask on a CRT display.
Neodymium is a rare metal that is very corrosion resistant. Its strong remanence and low temperature coefficient enable it to resist temperatures of up to 420 degrees Celsius. They may lose their magnetism if used over the maximum working temperature. It is critical to use a high-quality neodymium magnet in such applications. The chart below offers a full summary of various grades.
Neodymium magnet N55
The strength of a Neodymium magnet is determined by its use. If a sensor magnet must have a specified magnetic field intensity at a certain distance, the material utilized might be samarium cobalt 24. However, N55 may be adequate for holding applications, but N52 may cause sensor damage. The kind of magnet utilized may be an issue depending on the application.
The N55 magnet is widely used in a variety of industrial applications. It is notable for its saturation magnetization and strong attraction force. Its tremendous pull power, on the other hand, may induce bone fractures. The size to magnetic power ratio is the best technique to pick a magnet for a holding application. Magma is a maker of Neodymium magnets that are used in a variety of industrial applications. However, if you need a strong magnet in a tiny package, N55 is an excellent option.
A Neodymium magnet's strength is measured in megagauss (MGOe). The stronger the magnet, the higher the grade. In average, a Neodymium magnet N55 is up to 6% stronger than a Neodymium magnet N52. It is, however, easy to handle and is hence suggested for jobs with limited space. As a result, the N55 grade is suggested for your next magnetic project.
Because neodymium magnets are very strong, it is critical to handle them with prudence. Keep a magnet away from medical equipment, credit cards, and technological gadgets. Never put a magnet in the way of a youngster. A toddler might ingest the magnet and clog his or her respiratory and digestive systems. It may potentially cause an infection by closing the esophagus.
Although neodymium has the strongest strength of all of the neodymium kinds, it is also more prone to demagnetization and corrosion. Neodymium magnets are very corrosive and should never be exposed to extreme temperatures. This is particularly true for sintered Nd2Fe14B magnets, which corrode more easily. Furthermore, these magnets have the potential to lose their magnetic field and shatter into powder.
In terms of commercial quality, the N55 is the strongest commercially available Neodymium magnet. Although N52 remains the best grade, N55 outperforms its predecessors. Most magnet manufacturers presently provide this grade. This grade has a strength measurement range of 24 mgoe to 55 mgoe, which is five to six times that of N52. This grade is used to create high-quality magnetic components.
N42 neodymium magnets, on the other hand, provide an excellent mix of cost and performance. They are particularly suited to situations when the temperature is less than 80 degrees Celsius. The higher grades, on the other hand, are often more costly than the N42 grade. However, you will be rewarded with more strength since they can sustain a lower operating temperature. And this is precisely what your high-performance goods need.
As previously stated, Neodymium magnets, Samarium Cobalt Magnets, and Samarium Cobalt Magnets are available in a number of grades. Before selecting a magnet for your application, you need think about various variables. A magnet's strength is represented in its BHmax (Body-Hall-Max), which is a standard that determines its maximum energy density. This metric is sometimes referred to as Mega Gauss Oersteds (MGO) or Mega Gauss Oersteds.
