    Electric tool Hard Ferrite Magnets


    Relative Durability of Ceramic versus Rare Earth Magnets
    Along with their resistance to thermal stress, magnets also vary in their resistance to other stresses. NdFeB magnets are brittle and difficult to machine. They also corrode easily. SmCo magnets are slightly less brittle and are also difficult to machine, but have a high resistance to corrosion. SmCo magnets are also the most expensive type of magnet. Ceramic magnets are less costly than both SmCo and NdFeB magnets and have good resistance to demagnetization and corrosion.
    Benefits of Each
    Ceramic and neodymium magnets each have different benefits. Ceramic magnets are easy to magnetize. They are very resistant to corrosion and generally do not need extra coatings for corrosion protection. They are resistant to demagnetization by outside fields. They are stronger than natural magnets, though many other types of magnet are stronger than them. They are relatively inexpensive. Neodymium magnets are the most powerful of all permanent magnets. A neodymium magnet can lift more than any other type of magnet of the same size. They are extremely resistant to demagnetization by external magnetic fields.
    Drawbacks of Each
    Ceramic and neodymium magnets have different drawbacks as well. Ceramic magnets are extremely brittle and easily broken. They cannot be used in machinery that experiences a lot of stress or flexing. They become demagnetized if they are exposed to high temperatures (above 480 degrees Fahrenheit.) They have only a moderate magnetic strength, making them unsuitable for applications requiring powerful magnetic fields. Neodymium magnets are relatively more expensive than ceramic magnets. They rust very easily, and extra steps must be taken to protect them from corrosion. Neodymium magnets are also very brittle and will crack under stress. They lose their magnetism if exposed to temperatures above 175 to 480 degrees Fahrenheit (depending on the exact alloy used).

    FAQ

    1. What are neodymium magnets? Are they the same as "rare earth"?


    Neodymium magnets are a member of the rare earth magnet family. They are called "rare earth" because neodymium is a member of the "rare earth" elements on the periodic table. Neodymium magnets are the strongest of the rare earth magnets and are the strongest permanent magnets in the world.


    2. What are neodymium magnets made from and how are they made?


    Neodymium magnets are actually composed of neodymium, iron and boron (they are also referred to as NIB or NdFeB magnets). The powdered mixture is pressed under great pressure into molds. The material is then sintered (heated under a vacuum), cooled, and then ground or sliced into the desired shape. Coatings are then applied if required. Finally, the blank magnets are magnetized by exposing them to a very powerful magnetic field in excess of 30 KOe.


    3. How is the strength of a magnet measured?


    Gaussmeters are used to measure the magnetic field density at the surface of the magnet. This is referred to as the surface field and is measured in Gauss (or Tesla). Pull Force Testers are used to test the holding force of a magnet that is in contact with a flat steel plate. Pull forces are measured in pounds (or kilograms).


    4. What does the "N rating", or grade, of the neodymium magnets mean?


    The grade, or "N rating" of the magnet refers to the Maximum Energy Product of the material that the magnet is made from. It refers to the maximum strength that the material can be magnetized to. The grade of neodymium magnets is generally measured in units millions of Gauss Oersted (MGOe). A magnet of grade N42 has a Maximum Energy Product of 42 MGOe. Generally speaking, the higher the grade, the stronger the magnet.
