  • The Strong Arm Neodymium Magnets

    The best, brightest and strongest are always chosen to serve as the strong arm of the law to ensure that the protection of the innocent is in capable hands. In a similar way, neodymium magnets are some of the strongest and most capable magnets on the market today and are therefore often the choice for heavy duty applications that require magnets with immense amounts of strength. It should come as no surprise that neodymium magnets are hard core considering they come from the most respected branch of magnet materials, rare...

  • The What and Why of Neodymium Magnets

    Neodymium magnets are the most widely used form of natural magnets. A neodymium magnet is a rare-earth magnet made from a combination of iron, boron, and neodymium. Magnets made from these ingredients are permanent, and will never lose their magnetic pull. The first neodymium magnet manufacturer was General Motors and Sumitomo Special Metals in 1982. Currently, the neodymium magnet is the strongest created by any factory in the world. A neodymium magnet manufacturer creates the magnets in a variety of sizes for a variety of uses. The magnets are used...

  • A Shortage of Rare Earth Magnets Could Mean Big Trouble for Alternative Energy Innovation

    by Jenny Knodell, IQS Editor The most precious and valuable elements on Earth are buried deep beneath the surface, just waiting to be found. While diamonds, gold and silver are the first that come to mind, lesser known, exotic elements like neodymium, a rare earth magnet, may be the most invaluable of all. It isn't shiny or beautiful, but this silvery-grey magnet is expensive and highly sought after. Miners crawl deep into open pit mines, thousands of feet below the surface and appear with truckloads of the unimpressive looking chunks...

  • Wind Turbines: Change is in the Air for Manufacturing

    by Marjorie Steele, Editor for IQS Included in President Barack Obama's historical inauguration speech was a striking statement on his vision for the future of our energy industry. We will harness the sun and the winds and the soil to fuel our cars and run our factories. Perhaps this statement sounds a little over-the-top to you a little too epic. But honestly, what could be more epic than shifting the world's energy source from petroleum to wind energy, solar power and compressed air? So far it seems President Obama is...

  • Why supply of neodymium magnets is rising

    September 22, 2014 While manufacturers know neodymium magnets, also called NdFeB, are some of the most powerful magnets in the world, they might be surprised to learn they are some of the smallest and lightest, which make them ideal for tech firms. Trends in the tech world are headed to thinner and lighter devices and demand for neodymium magnets is likely going to maintain upward growth. And supply for these magnets will also increase along with demand. Business intelligence firm Research and Markets predicts the market for neodymium magnets...

Industry Information

Neodymium Magnets

Neodymium is an element that is soft and silvery in appearance. It is also a rare earth element, which is a category of seventeen elements of the lanthanide series on the periodic table that are naturally found together and difficult to separate from one another. They can also retain their magnetism more efficiently than magnets made from ferrous materials. Neodymium is the strongest and most reactive of all the rare earth elements, and are used in applications that require exceptionally powerful magnets. In terms of performance, cost, and size, neodymium magnets are highly recommended over other types of magnets.

Neodymium magnets, or neo magnets, are made from a compound of neodymium, boron, and iron. Like all rare earth magnets, neo magnets are exceptionally resistant to demagnetization, and they have a larger strength to size ratio than other magnets. Although it costs more to manufacture neo magnets, they require significantly less volume due to their high strength to size ratio. Neo magnets are fabricated similarly to ceramic magnets. Neo magnets are made by grinding the material into powder, and then forming it into a particular shape. A magnetic field is then applied for orientation, and they are sintered until the desired density is achieved. This fabrication process enables manufacturers to make neodymium magnets in a wide range of configurations, such as blocks, rings, and discs.

There are two main processes of manufacturing neo magnets. The first is classical powder metallurgy, or the sintered metal method. This process involves using a furnace to melt raw materials and mix them together, and then placing the molten material into a mold as it cools, solidifies, and takes on the mold’s shape. Rapid solidification is the process of using a melt spinning technique to create a neodymium magnet. Melt spinning is a process that quickly cools molten raw material by a wheel that is cooled internally by water or liquid nitrogen and is rotated. The liquid is then dripped onto the wheel, where it rapidly cools and solidifies.

Neo magnets are a permanent magnet, meaning that it will not lose its magnetic field regardless of the external conditions. The neo magnet is the strongest and most widely used out of all the types of magnets. Examples of applications that utilize neo magnets include DC motors, computer disc drives, microphone assemblies, magnetic fasteners, cordless tools, magnetic separators, servo motors, and linear actuators.

Neodymium magnets outdo samarium cobalt magnets in terms of cost and strength, which makes them a popular choice for so many applications. Therefore, neo magnets are used more frequently in a multitude of applications. An important factor for magnets to have in carrying out various functions is to have magnetic permanence, or the ability to retain magnetism under circumstances such as heat, electric fields, corrosion, and vibration. Applications in which magnetic permanence is highly critical include medical, automotive, and industrial equipment. As powerful as their magnetic force can be, neo magnets do not hold up well against corrosion and relatively low temperatures, such as around 200 degrees Celsius (392 degrees Fahrenheit). In addition, they can easily be cracked or chipped. Therefore, neo magnets are almost always equipped with a protective metal coating made of either nickel or another strong type of metal. Samarium magnets have a significantly higher heat threshold, and are used in applications in which the heat level is higher than what neo magnets can tolerate.

In addition to a low heat threshold, there is another drawback to a neo magnet. Because of how powerfully they can be drawn to each other, neo magnets have the potential of shattering if two or more of them are too close in proximity to one another. If a neo magnet is larger than several cubic centimeters, it can pose a hazard to workers who handle them. If two of these magnets are too close, body parts can be sandwiched between them, and possibly break bone. Therefore, in utilizing larger neo magnets, safety precautions must be in place for anyone who works with or near them.

The demand for rare earth magnets has been on the rise in many industries and facilities due to the automotive industry beginning to explore fuel sources other than petroleum. Neo magnets are an important component in certain pieces of equipment such as wind turbines and electric motors, and the scarcity of lanthanoid ore has become a concern. Fortunately, industries such as aerospace, medical, automotive, and electronics have explored uses for rare earth magnets. Rare earth magnets could see some growth as an alternative energy source in the near future.
