Alnico is a commonly used permanent magnet, also known as a stock magnet. Alnico retains its magnetic properties for a long time, which is why it is considered a permanent magnet. Another benefit of using alnico magnets is that it has excellent temperature stability and works very well in high temperature applications. Industrial and manufacturing industries use alnico magnets, which can be used in high temperatures of 425 - 525 degrees Celsius. Alnico is affordable and easily customized to the size and strength you need. Alnico magnets are good choices for industrial or manufacturing applications because of their many benefits. Whether you require a magnet for an industrial or consumer application, alnico magnets are a good choice.
Ferrite magnets are often made from a chemical compound that contains iron oxide and ceramic. Sintering and pressing ceramic and magnetic powders is the process for making ceramic ferrite magnets. When sintering, which is a process often used in manufacturing magnets, two main materials are combined using heat until they stick together. Described as being hard and brittle, ceramic magnets are affordable to produce.Ceramic ferrite magnets can be categorized as either hard ferrites or soft ferrites, although these terms are misleading. The terms hard and soft ferrite are misleading because the difference between these two magnets does not lie in the density of the material but instead in the intensity of the magnetic field. Soft ferrite magnets do not need as intensive of a magnetic field to de-magnetize as hard ferrite. The unique quality of a ceramic magnet is that it can be applied to flexible fabrics, which makes them great for crafts, decorations and use in home, school or work. There are a wide variety of uses for ceramic magnets .
Neodymium magnet is a rare earth magnet made from neodymium, a chemical element with the symbol Nd and atomic number 60. Present in the ore minerals monazite and bastnasite, neodymium is a silvery, soft metal that easily tarnishes. Neodymium magnets are preferred for certain applications because of their strength and ability to perform in extreme conditions. Consider neodymium magnets in situations where you need to use maximum energy and work in service temperatures up to 150 degrees Celsius. Neodymium is stronger than ferrite or alnico products. There are many advantages to using neodymium magnets and products made from neodymium. The major pros to neodymium are its strength, popularity, affordability and ability to perform in frigid conditions, however there are still some cons to using this rare earth magnet. Unlike other rare earth magnets, such as samarium-cobalt, neodymium magnets have a low Curie temperature and as a result can't perform in high temperatures, which means that it could lose its magnetism in environments that are too hot. Neodymium performs extremely well in very cold temperatures. Unlike samarium-cobalt, another rare earth magnet, neodymium is less resistant to oxidation which means it is ultimately not as durable and must have a surface treatment applied in order to protect the magnet from being scratched. In order to protect neodymium magnets from cracks and corrosion often manufacturers will apply surface treatments in the form of plating or coating in the form of nickel, tin, zinc or gold. Oxidization and cracking can be minimized by applying a good coating or plating to the neodymium magnet..
A powerful type of magnetic strip is a high energy strip magnet which has a nitrile rubber base. MGOe (megagaussoersteds) is a measurement of the amount of magnetic energy stored in a magnet. Available in 1.1 - 1.6 MGOe, high energy strip magnets are more powerful than normal flexible magnetic strips. Magnetic strips have adhesive backing, are often laminated and come in many different shapes and sizes. Ideal for laminating and punching, flexible magnetic strips can be cut to length, are available in a number of sizes and widths and will stick to any ferrous surface. You can use magnetic tape for a number of uses around your home, in school or at work. Magnetic tape is really useful - on the front is an adhesive face and the back has a magnetic face. Magnetic tape can be used for a number of different applications because it is so affordable, thin, flexible and versatile.
Block magnets are durable and are a good choice for industrial settings. Depending on your needs, the composition you choose for your block magnet will differ. You should consider the purpose and conditions you will use the magnet for before you choose the type of block magnet to use. If you are using the magnet for a heavy duty or industrial application consider using a rare earth magnet instead of a ceramic or alnico magnet. In addition to the strength of the magnet you need to consider the temperature and keep in mind that some magnets lose or maintain magnetism at different temperatures. Depending on the need of magnet choose one that is difficult or easy to demagnetize.
