Neodymium magnets for lesss are actually composed of neodymium, iron and boron (they are also referred to as NIB or NdFeB magnets for lesss). 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 magnets for lesss are magnets for lessized by exposing them to a very powerful magnets for lessic field in excess of 30 KOe.
Frequently Asked Questions
Q: What are neodymium magnets for lesss? Are they the same as "rare earth"?
A: Neodymium magnets for lesss are a member of the rare earth magnets for less family. They are called
"rare earth" because neodymium is a member of the "rare earth" elements on the
periodic table. Neodymium magnets for lesss are the strongest of the rare earth magnets for lesss and are
the strongest permanent magnets for lesss in the world.
Q: What does the "N rating", or grade, of the neodymium magnets for lesss mean?
A: The grade, or "N rating" of the magnets for less refers to the Maximum Energy Product of the
material that the magnets for less is made from. It refers to the maximum strength that the
material can be magnets for lessized to. The grade of neodymium magnets for lesss is generally
measured in units millions of Gauss Oersted (MGOe). A magnets for less of grade N42 has a
Maximum Energy Product of 42 MGOe. Generally speaking, the higher the grade, the
stronger the magnets for less.
Q: What is the difference between the different platings and coatings?
A: Choosing different coatings does not affect the magnets for lessic strength or performance of
the magnets for less, 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 magnets for lesss. 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 magnets for lesss.
♦ 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 magnets for lesss
have the same characteristics as nickel plated ones, but with a gold finish
