2.Customization:available
3.Grades:N,M,H,SH,UH,EH
permanent patent n35 ndfeb magnet:
Key features:
1)The most powerful magnets available,the neodymium iron boron family since the 1980s
2)Being manufactured by a powder metallurgical process which involves the sintering of powder compacts under vacuum
3)Grinding and slicing can be operated into the desired shape and size
4)The material is so reactive with moisture and ozygen,coating may be applied depending on the expected environment
Coating properities:
coating performance | coating thickness | corrosion resistant in salt fog(Hr) | coating porosity | magnetic flux lose | color |
| Zn | 10-15 | 24 | <0.1 | <0.2 | white |
| Double-Ni | 15-20 | 24 | <0.2 | <0.3 | sliver |
| Ni-Cu-Ni | 15-30 | 48 | <0.1 | <0.1 | sliver |
| Zn-Ni | 10-20 | 72 | <0.1 | <0.1 | multicolor |
| Epoxy | 10-50 | 200 | black | ||
| Passivation | 1-5 | 8 | sliver |
