Brief Introduction
Our company has been specializing in producing NdFeB magnet for 16years ,We
developed many permanent magnet applications , we have experience on designing magnetic flux
and assembling complicated magnetic construction such as Halbach ring magnets.

Our company ordered special SUS304 ,SUS316, stainless tube as outside shell and
select quality permanent magnet to combine strong magnet bar , we have special equipment to
Process them , we can guarantee the top flux 1.3T of bar magnet .And they can be used in 350
Degree C (top temperature) . Th e life can be 5-8 years .

We delivered bar magnet with Eco -friendly packaging material , we deliver the goods promptly . And our price of grate magnet bar will be competitive all over the world .
