Magnet Fuss: Magnets to Suit Every Need
Alnico is considered a stock magnet, which is a commonly used type of permanent magnet. Alnico retains its magnetic properties for a long time, which is why it is considered a permanent magnet. Alnico magnets have excellent temperature stability and can perform in high temperatures. Alnico magnets are often used in industrial and manufacturing industries because they can withstand high temperatures of up to 525 degrees Celsius. Alnico can be produced using small, custom-ground batches, which makes it very economical. The benefits to using alnico magnets are great and include their strength, affordability, resistance to extremely high temperatures and the fact that they maintain their magnet qualities for long periods of time. For a variety of industrial and consumer applications alnico magnets are a great choice.
Ceramic and iron oxide are usually the base materials for ceramic ferrite magnets. Ceramic magnets are made by pressing and sintering magnetic powders and ceramic. Sintering is a process used in manufacturing magnets when two main materials are combined and then melted down to the point where they stick to each other. Ferrite magnets are described as being hard and brittle.The two main types of ceramic ferrite magnets are known as soft ferrites and hard ferrites, however the terms ‘hard’ and ‘soft’ in these names are misleading. The difference between hard and soft ferrite actually is in the intensity of the magnetic field required to demagnetize the material, not in the density of the material as the name suggests. Soft ferrite magnets do not need as intensive of a magnetic field to de-magnetize as hard ferrite. You can use ceramic magnets at home, in school or in the work place because they can be applied to many materials, such as flexible fabrics, which makes them great for many uses. In actuality, there are a variety of different uses for ceramic ferrite magnets.
Neodymium magnet is a rare earth magnet made from neodymium, a chemical element with the symbol Nd and atomic number 60. Neodymium is present in the ore minerals bastnasite and monazite and is described as a soft, silvery metal that easily tarnishes in the air. Neodymium magnets are preferred for certain applications because of their strength and ability to perform in extreme conditions. For applications using temperatures of 125 – 150 degrees Celsius neodymium is the preferred magnetic choice. Neodymium is stronger than ferrite or alnico products. The advantages to using neodymium magnets and other products made from neodymium are numerous. Despite its strength, affordability and popularity neodymium does have a couple of drawbacks. A major con to using neodymium is that it can lose its magnetism in hot environments because of its low Curie temperature. Neodymium performs extremely well in very cold temperatures. Neodymium is less durable than other rare earth magnets and must have surface treatments applied to prevent scratching. Neodymium is a brittle magnet, which can form cracks and is vulnerable to corrosion. Therefore, manufacturers will apply a surface treatment such as gold, nickel, zinc or tin plating or coating as a protective measure. Oxidization and cracking can be minimized by applying a good coating or plating to the neodymium magnet..
There are many uses in a variety of industries for flexible magnetic strips. Magnets use magnetism to work. When placed next to a ferrous metal or another magnet, the force of magnetism will pull or attract the metal or magnet. A magnet will attach itself to an object that it is attracted to due to the force of magnetism. The uses for magnets are wide and which is why they are often used in fields such as industrial, marketing, commercial and retail. Of all the types of magnets, flexible magnetic strips are the most dexterous. The advertising uses of flexible magnetic strips are numerous and include purposes designed for labels, vehicle signs, signage and point of sale displays. Flexible magnets are often used for fridge magnets, planning boards and printed magnets. The refrigerator is the center of activity in your home which is why fridge magnets in particular are such a great advertising tool. With a fridge magnet customers never have to search for your information..
Block magnets are available in many different thicknesses, widths and sizes although they are generally rectangular in shape. When you hear the word magnet, and close your eyes and picture a magnet, you probably are thinking about a block magnet. The block magnet is a popular choice in a number of different settings because of its versatility and affordability. Used in many different settings like industrial and educational environments block magnets have many uses including recreational, decorative and . Block magnets are very customizable and are surprisingly affordable and easy to customize for your specific need. A large variety of magnets are carried in stock by most magnet manufacturers but if they don’t carry what you are looking for then you can affordably ask them to make you what you are looking for. It doesn’t take long or cost a lot of money to have a magnet manufacturer customize a magnet for you..
For some reason you are unable to specialty magnets like you thought? Plenty of people read about rare earth permanent magnets and it opened their eyes.
