High Grade Sintered Neodymium Permanent Rare Earth Magnet Bars

 

 

Description:

 

1. The magnet bar is consisted of stainless steel tube and strong NdFeB magnet. 

2. The standard size of tubes is 30mm* 15mm we supply. The size length will vary at your request.

3. Performance of magnet bars range form 3000 to 12000 GS, can be customized by order.

4, The magnet bars can get rid off the oxide particles, particles and impurity in material, widely used in the recycling industry to separate ferrous from non-ferrous items .

5. All of magnet bars are waterproof.
