What industries can custom neodymium magnets be used in?
Custom neodymium magnets can be used in a wide variety of industries, including the aerospace and defense industries, the automotive and transportation industries, consumer products, computers, sensor magnets, PM motors, the oil and gas industries, the communication industries, the medical, and more.
What are the strengths and weaknesses of custom neodymium magnets?
Neodymium magnets are best known for being the strongest magnetic material available. These rare earth magnets are composed of neodymium, iron, and boron, and exhibit the highest maximum energy product out of all available permanent magnet materials. They are powerful, affordable, and appropriate for use in environments of up to 200 °C. Due to their high strength, a neodymium magnet in a very small size can still deliver a very high performance. The greatest weakness of neodymium magnets is that they are vulnerable to corrosion if exposed to the elements—however, this problem can easily be resolved by adding a protective coating—usually of nickel—to protect the magnet from corrosion. In addition, the correct grade of neodymium must be selected to prevent demagnetization at the operating temperature of the application.
What are the different options for custom neodymium magnets?
Bunting-DuBois is able to provide neodymium magnets in rings, blocks, discs, arcs, triangles, trapezoids, and many other shapes, as well as a variety of sizes. While the standard coating is nickel, neodymium magnets may also be coated with zinc, tin, copper, aluminum, epoxy, gold, and silver. Additionally, Bunting-DuBois offers plastic bonded neodymium magnets.
What are plastic bonded neodymium magnets?
Bonded neodymium magnets can be produced through either a compression bonding or injection molding method. Bonded neodymium magnets can be manufactured to a net shape with high tolerances, and without requiring any further machining. They are valuable due to their suitability for high volume applications, their high durability and shock resistance, and resistance to corrosion.
What makes custom neodymium magnets from Bunting-DuBois unique?
Custom neodymium magnets from Bunting-DuBois are unique due to our company’s unique engineering design and manufacturing. Our Finite Element Analysis modeling programs allow our experienced team of engineers to analyze magnetic problems and arrive at exact, targeted solutions that are then extensively tested. We also offer rapid prototyping of your designs, which allow you to quickly see how your custom magnet or magnetic assembly will function in a real-life environment. Bunting-DuBois can manufacture magnets and magnetic assemblies in any quantity, and we guarantee on-time delivery and extensive product quality checks. We also have a diverse supply chain—specifically, our supply chain for injection molded and compression bonded magnets does not rely on China. Bunting-DuBois’s manufacturing supply chain structure protects us from supply chain disruptions and allows us to be a reliable, stable source of custom magnets and magnetic assemblies.
