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