Meeting your magnetic permeability requirements
Low-magnetic-permeability fasteners are essential in nuclear, fusion reactor, particle accelerator and sensitive electronics and instrumentation applications to minimize magnetic interference. Conversely, we offer grades with high magnetic permeability.
| Our low magnetic permeability grades | Relative magnetic permeability at 20°C* |
|---|---|
| BUMAX® 88 | 1.006 |
| BUMAX® 109 | 1.007 |
| BUMAX® NITRO | 1.003 |
| BUMAX® SA | 1.007 |
| BUMAX® HE | 1.003 |
* As magnetic permeability depends on temperature, dimensions, delivery form and the degree of cold work, this data should be used as guidance only.
| Our high magnetic permeability grades | Relative magnetic permeability at 20°C* |
|---|---|
| BUMAX® DX | 100 |
| BUMAX® SDX | 100 |
| BUMAX® ULTRA | 1,000 |

About magnetic permeability
Relative magnetic permeability refers to a material’s ability to attract and conduct magnetic lines of flux. The more conductive a material is to magnetic fields, the higher its permeability.
Magnetic permeability depends on temperature, dimensions, delivery form and the degree of cold work in manufacturing. Contact us to discuss your magnetic permeability requirements.
