Super Strong Magnet Neodymium Ring N52 Axial For Door Holder
Identify
1. Usually with a magnet of the same specification placed on a
surface that can be adsorbed, such as: patch, blade, iron door,
etc., with the feel to identify the size of the magnetic force
2. Use electronic scale: the weak magnetic force of the magnet is
generally related to its density. If the density is small, the
magnetic force is relatively small, and the weight is heavy, the
magnetic force is relatively large. On the contrary, the light
magnetic force is small.
Grades of Neodymium Magnet
Neodymium( NdFeB )magnets are the type of rare earth magnet
commercially available and are manufactured in a wide range of
shapes,sizes and grades. Neodymium magnets are all graded by the
material they are made of. As a very general rule, the higher the
grade (the number
following the 'N'), the stronger the magnet. The highest grade of
neodymium magnet currently available is N52. Any letter
following the grade refers to the temperature rating of the magnet.
If there are no letters following the grade, then the magnet
is standard temperature neodymium. The temperature ratings are
standard (no designation) - M - H - SH - UH - EH.
Platings/Coatings
Neodymium magnets are a composition of mostly Neodymium, Iron and
Boron. If left exposed to the elements, the iron in the magnet
will rust. To protect the magnet from corrosion and to strengthen
the brittle magnet material, it is usually preferable for the
magnet to be coated. There are a variety of options for coatings,
but nickel is the most common and usually preferred. Our nickel
plated magnets are actually triple plated with layers of nickel,
copper, and nickel again. This triple coating makes our magnets
much more durable than the more common single nickel plated
magnets. Some other options for coating are zinc, tin, copper,
epoxy,
silver and gold. Our gold plated magnets are actually quadruple
plated with nickel, copper, nickel and a top coating of gold.
Application

vehicles, elevators, security monitoring, dishwashers, magnetic
cranes, magnetic filter.
Common direction of magnetization
1> Disc, cylinder and Ring shape magnet can be magnetized
Axially or Diametrically.
2> Rectangle shape magnets can be magnetized through Thickness,
Length or Width.
3> Arc shape magnets can be magnetized Diametrically, through
Width or Thickness.
