Product Description:
Bonded Neodymium Magnet is a kind of permanent magnet made of
neodymium iron boron material. It has the advantages of high
performance, high magnetic energy product, high coercive force, low
temperature coefficient, excellent corrosion resistance, strong
shock resistance and low cost. It has been widely used in many
applications, such as spinder motor, stepping motor, synchronous
motor, DC motor, brushless motor, etc.
Bonded neodymium magnet is a kind of permanent magnet with bonded
arched NdFeB magnet. It can be customized into different shapes,
such as disc, block, cylinder, ring, etc. The surface of magnet can
be coated with epoxy, nickel, parylene, etc. to protect the magnet
from corrosion or other environment factors. The minimum order
quantity (MOQ) is 100 pieces.
Bonded neodymium magnet is a high-performance and cost-effective
product for many applications. It has strong magnetic field with
high coercive force, which can be used in many industrial
applications. It is also an excellent choice for small-scale
projects due to its low MOQ requirement.
