Powerful new grade of Neodymium added to our magnet offerings A powerful new grade of Neodymium is now available at Dura Magnetics: 55 MGOe Neodymium. As the strongest rare earth magnetic material available for commercial use, N55M is about five- to six-percent stronger than N52 MGOe, our previously highest available grade. Available N55M stock magnets […]
Each of the wide variety of magnetic materials available requires specific storage and handling procedures for both the safety of the user and integrity of the magnet. Why handling and storage conditions are important Improperly handled and stored magnets present risks: Risk of bodily harm or injury Risk of damage to the magnet Risk of […]
Choosing an appropriate magnet material is a crucial part of the design of a magnet assembly, as it will largely impact the performance of the final product. Here are a few tips from Dura’s decades of design experience to consider when selecting a material and grade for your assembly. Considerations for choosing a magnet type […]
In January 2020, the John S. McCain National Defense Authorization Act was instituted, adding neodymium to the list of DFARS materials. Through this act, neodymium is prohibited for government defense contracts if sourced from China, Russia, North Korea, or Iran. To be compliant with this update to the Defense Federal Acquisition Regulation Supplement (DFARS), it […]
Rare-earth Neodymium magnets can have an attractive pull force of up to 1,000 times the weight of the magnet. This property allows engineers to specify a particularly small magnet for a stay-in-place operation. It can also make it difficult to find an appropriate mechanical fastener (screw / bolt etc.) to hold that small magnet in place. Enter Dura’s adhesive-backed Neodymium magnet discs. Because these magnets are designed with the fastener “built-in,” they give design engineers flexibility and cost savings by allowing production / assembly staff to apply the magnets instantly to a work piece without the need for another component fastener.
We occasionally get inquiries and manufacturing prints identifying a custom magnet shape using the abbreviation Neo. Because shorthand works – both internally and in discussions with our customers – we likewise sometimes refer to a Neodymium magnet as Neo or NdFeB. Of the rare earth element magnets, Neo magnets are the most commonly specified because they have the highest known energy product for their mass. One might possibly expect the Neo name to mean “new” – and that could be a reasonable assumption based on the fact that they were initially created relatively recently in 1984. The abbreviated name, however, actually comes from the element Neodymium – or Nd.
As part of our ongoing effort to provide magnet-related resources that may be useful to those in the field, we have added to our collection of magnetic property calculation tools. This particular resource is a magnetic force calculation utility that aids in estimating the attractive (pull) force of Samarium Cobalt magnets.
At Dura Magnetics, we field occasional calls and emails from customers and prospective customers inquiring about a neodymium magnet grade called N52. So what exactly is N52, do you really need it, and what are some of the potential challenges associated with this type of neodymium magnetic alloy?
Regular visitors to our site may have noticed a newly revised Neodymium Magnets section. The new material is designed to better serve the information needs of our different clients, so you’ll see everything from a revised Stock Neodymium Magnets section and a new Available Neodymium Magnet Grades to information on made to print and custom […]
