Know about the Applications Of Neodymium Magnets

Neodymium may be a rare-earth element metal component mischmetal which may be wont to create powerful magnets. Neodymium magnets are the strongest known relative to their mass, with even small magnets ready to support thousands of times their own weight. Although a “rare” earth metal, neodymium is widely available, resulting in easily obtainable raw materials to manufacture neodymium magnets. Due to their strength, neodymium magnets are utilized in a broad range of applications, including jewelry, toys, and computer equipment.

As neodymium magnets are so strong, their uses are versatile. They’re produced for both commercial and industrial needs. For instance, something as simple as a bit of magnetic jewelry uses a neo to stay the earring in situ. At an equivalent time, neodymium magnets are being sent into space to assist collect dust from the surface of Mars. Neodymium magnets’ dynamic capabilities have even because they getting used in experimental levitation devices.

Neodymium Magnet

Neodymium magnets also referred to as NIB magnets, are measured from N24 to N55 on the magnetism scale that goes up to N64, which may be a theoretical magnetism measurement. Counting on the form, the composition, and therefore the production method, NIB magnets can fall anywhere during this range and supply serious lifting strength.

In order to construct a neo, as they're sometimes also called, manufacturers collect rare-earth element metals and sift them to seek out usable Neodymium Magnets, which they need to break away other minerals. This neodymium is ground up into a fine powder, which may then be resealed into the desired shape once combined with iron and boron. Thanks to the iron during a neo, its properties almost like other ferromagnetic materials, including mechanical fragility.

Neos also are vulnerable to temperature differences and may crack or lose their magnetism in higher temperatures, usually above 176 degrees Fahrenheit. Some specialized neos work on higher temperatures, but generally above that level, they fail to properly function. In cooler temperatures, neos are going to be fine. Because other sorts of magnets don’t lose their magnetism at these high temperatures, neos are often bypassed for applications that will be exposed to great amounts of warmth.

Choosing a Rare Earth Magnet

The term rare-earth element magnet may be a generic name wont to describe two sorts of magnetic material: samarium cobalt and neodymium iron boron. Both of those magnetic alloys utilize Rare Earth Magnet elements because the magnetic constituents and therefore the characteristics offered by both material types lend themselves to specific applications.

Over 30 years ago, neodymium magnets were developed by General Motors and Sumitomo Specialty Metals in response to the rising cost of samarium cobalt. Since its inception, neodymium iron boron has undergone a numerous enhancements, and today, this material is that the hottest and widely used magnet alloy. It’s also important to understand that there are many patents covering the assembly of sintered neodymium iron boron magnets. Here at Dura, the neodymium iron boron we supply is licensed and compliant to all or any applicable patents.

Of all magnetic materials (including other rare earths), neodymium iron boron offers the very best available magnetic energy density with (BH)Max values starting from 33 to 52 MGOe. This property allows designers to use relatively small amounts of magnetic alloy in comparison to other magnetic materials.

Although the smaller magnets and increased savings related to neodymium might suggest choosing a high strength neodymium magnet is that the most suitable option for all applications, this is often not always the case. Ignoring important characteristics like operating temperature or the magnet’s ability to face up to corrosion may cause premature failure and substandard performance. Alternative heat grades of neodymium iron boron and various surface treatments are available when the trials of the appliance demand it.

Most of the main Motor arc Magnets manufacturers (including Dura) offer charts and data describing the physical characteristics of obtainable magnets grades, including rare-earth element magnets. This information may be a huge help when selecting a rare-earth element magnet, but it's only a start line.

The different magnetic and physical properties of those two magnetic alloys means choosing the right rare-earth element magnet is more complex than locating a web vendor offering an appropriate size. Ultimately, selecting the right rare-earth element magnet is application driven, and your best bet is to talk with an engineer to debate your specific needs.
