Permanent magnet materials contain iron elements, iron shows the most significant ferromagnetic properties of all elements, which is why it exists in the most powerful magnets. However, iron is highly reactive to water, making magnets with a high iron content very susceptible to corrosion. Other ferromagnetic elements used in different types of permanent magnets include nickel, cobalt, gadolinium, and dysprosium, all of which have an effect on magnetic strength and corrosion resistance. There are many factors to consider when exploring custom magnetic components, and corrosion resistance is one of the key factors you just considered, so take a look at our breakdown of the corrosion resistance of each magnetic material. 1. NdFeb magnet Currently, the strongest commercial permanent magnet on the market is Ndfeb magnets , but due to their high iron content (64-68%), they are also highly corrosive in wet environments. Modern manufacturing techniques have found that small amounts ...

  I am sure you must have heard about rare earth magnets as they are very useful these days. Basically, rare earth magnets are those elements which are made of the alloys of all the rare earth elements. Rare earth materials are permanent in nature and they are much stronger than alnico and ferrite. They were developed around 1970s and 80s and they have the magnetic field of 1.4 tesla. They are extensively brittle and can corrode easily. To prevent them from corrosion and chipping they are usually coated with a protective shield.   The two most popular rare earth elements are samarium-cobalt and neodymium. In this article, I would mainly like to tell you about the essential features of these rare earth elements.   Neodymium Magnet: It is also known as Neo, NdFeB and NIB. It comes under the category of permanent elements and was discovered in 1980s. It is the strongest magnet known to man is made of the alloy of iron, boron and neodymium. All these elements togeth...

  What is Neodymium Iron Boron Magnet ？ A Neodymium magnet (also known as "NdFeB", "Neo" or rare earth magnet) is a permanent magnet composed of neodymium, iron and boron. They are one of the strongest rare earth magnets of all permanent magnets, and are stronger than samarium cobalt (SmCo), alnico, and ferrite. Besides high magnetic strength, they are also comparatively affordable, which makes them ideal for an extensive array of consumer, business, industrial and technological uses. NdFeB magnets (neodymium magnets) provide maximum performance with the smallest magnet size. The Neodymium permanent magnet is used in almost all industries, such as the automobile, aeronautics, wind power turbine, military, illumination, food production, separation, electric motor and generating industries. 1-neodymium-permanent-magnet Permanent NdFeB magnets Uses NdFeB magnets are available in several different sizes and variations, including disc magnets, neodymium ball m...

  Neodymium magnets are the most widely used rare-earth magnets. They are permanent magnets that are made from neodymium alloy, boron and iron to form a tetragonal crystalline structure. Permanent means that they are able to retain the magnetic properties over high periods of time constantly generating magnetic field from their surroundings. These magnets are actually the strongest permanent magnet types available commercially and they have even replaced other magnet types in different application in making modern products that need the strength. Today you will find the magnets in cordless tools as motors, fasteners and even in hard disk drives. Below are some of the common uses of neodymium magnets. Medical industry uses - The neodymium magnets are used extensively for magno-therapy by medical practitioners and physiotherapists to reduce pain. They are also sold as medical devices to wear as shoe insertions, blankets and bracelets. They stabilize iron content and hemoglobin c...
