Sintered NdFeB magnets greatly
expand the applications of permanent magnets.They are widely used in
the fields of transportation,energy,communications,home
appliances,machinery and medical equipment and have become indispensible
function materials in manufacturing and daily life.
Our manufactures
sintered neodymium magnet in custom sizes upon requirements.Our
machining capabilities provide perfect solutions for both regular shapes
and special shapes of NdFeB magnet,with good quality and maintain the
price advantage.
What size of NdFeB magnet with adhesive are available?
Relying
on experienced production team and strong maching capability,most sizes
of neodymium magnet can be produced with very high quality,and the
tolerance can be controlled within +/-0.05mm or +/-0.1mm.

What grade of neodymium magnet you may need?
Basis
on different temperature resistrance,the neodymium magnet are divided
into N,M,H,SH,UH,EH,AH series,and the corresponding maximum operating
temperature is 80℃,100℃,120℃,150℃,180℃,200℃,220℃.
In
the same serires,the higher the grade of NdFeB magnet,the more
magnetism it is.For example,in N series,N52 grade have more magnetic
power than N35 grade,and the N55 grade is the strongest one.
For
initial projects,we are happy to provide magnetic technology support
and made magnet samples according to your requirements for prototyping
or testing needs.
