Grades
N35, N38, N42, N38SH...what does it all mean? 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. You find the temperature rating of each grade on our Specifications of Neodymium Magnets Page.

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. Some other options for
coating are zinc, tin, copper, epoxy, silver and gold.
Machining :
Neodymium material is brittle and prone to chipping and cracking,
so it does not machine well by conventional methods. Machining the
magnets will generate heat, which if not carefully controlled, can
demagnetize the magnet or even ignite the material which is toxic
when burned. It is recommended that magnets not be machined.
Packing :
Our packing is done very professionally in a 8 segment thermocole
box,With magnets kept in cartons at each mini segment.This doesn’t
cause magnetic forces to interact internally in the packing.Thereby
there is no risk of chipping the magnets due to cartoons sticking
together etc.Moreover the ourer carton is covered by PP sacks to
make it weatherproof.
We deliver goods through Air shipment and Sea shipment.
We can provide you the Best price for the Good quality product.
