Neodymium super neodymium round magnetsic rings are actually composed of neodymium, iron and boron (they are also referred to as NIB or NdFeB super neodymium round magnetsic rings). The powdered mixture is pressed under great pressure into molds. The material is then sintered (heated under a vacuum), cooled, and thenground or sliced into the desired shape. Coatings are then applied if required. Finally, the blank super neodymium round magnetsic rings are super neodymium round magnetsic ringized by exposing them to a very powerful super neodymium round magnetsic ringic field in excess of 30 KOe.
Frequently Asked Questions
Q: What are neodymium super neodymium round magnetsic rings? Are they the same as "rare earth"?
A: Neodymium super neodymium round magnetsic rings are a member of the rare earth super neodymium round magnetsic ring family. They are called "rare earth" because neodymium is a member of the "rare earth" elements on the periodic table. Neodymium super neodymium round magnetsic rings are the strongest of the rare earth super neodymium round magnetsic rings and are the strongest permanent super neodymium round magnetsic rings in the world.
Q: What does the "N rating", or grade, of the neodymium super neodymium round magnetsic rings mean?
A: The grade, or "N rating" of the super neodymium round magnetsic ring refers to the Maximum Energy Product of the material that the super neodymium round magnetsic ring is made from. It refers to the maximum strength that the material can be super neodymium round magnetsic ringized to. The grade of neodymium super neodymium round magnetsic rings is generally measured in units millions of Gauss Oersted (MGOe). A super neodymium round magnetsic ring of grade N42 has a Maximum Energy Product of 42 MGOe. Generally speaking, the higher the grade, the stronger the super neodymium round magnetsic ring.
Q: What is the difference between the different platings and coatings?
A: Choosing different coatings does not affect the super neodymium round magnetsic ringic strength or performance of the super neodymium round magnetsic ring, except for our Plastic and Rubber Coated Magnets. The preferred coating is dictated by preference or intended application. More detailed specifications can be found on our Specs page.
♦ Nickel is the most common choice for plating neodymium super neodymium round magnetsic rings. It is actually a
triple plating of nickel-coppernickel. It has a shiny silver finish and has good resistance to corrosion in many applications. It is not waterproof.
♦ Black nickel has a shiny appearance in a charcoal or gunmetal color. A black dye is added to the final nickel plating process of the triple plating of nickelcopperblack nickel.
NOTE: It does not appear completely black like epoxy coatings. It is also still shiny, much like plain nickel plated super neodymium round magnetsic rings.
♦ Zinc has a dull gray/bluish finish, that is more susceptible to corrosion than nickel. Zinc can leave a black residue on hands and other items.
♦ Epoxy is basically a plastic coating that is more corrosion resistant as long as the coating is intact. It is easily scratched. From our experience, it is the least durable of the available coatings.
♦ Gold plating is applied over the top of standard nickel plating. Gold plated super neodymium round magnetsic rings have the same characteristics as nickel plated ones, but with a gold finish.
