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.
Demagnetization :
Rare Earth magnets have a high resistance to demagnetization,
unlike most other types of magnets. They will not lose their
magnetization around other magnets or if dropped. They will
however, begin to lose strength if they are heated above their
maximum operating temperature, which is 176°F (80°C) for standard N
grades. They will completely lose their magnetization if heated
above their Curie temperature, which is 590°F (310°C) for standard
N grades. Some of our magnets are of high temperature material,
which can withstand higher temperatures without losing strength.
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.
