magnetic permeability 2.0

magnetic permeability 2.0

(OP)
Is there a reference that defines a category for a magnetic permeability of 2.0? I understand the comparison to air=1.0, but it would be helpful if this could be described as "nonmagnetic".

eg: for review of CRES fasteners (MS24694C) to install near to a magnetic flux valve.

Thanks for your help.

RE: magnetic permeability 2.0

A material with a magnetic permeability of 2.0 would not generally be classified as nonmagnetic.

The rules/specifications vary, but most people using CRES fasteners would want the magnetic permeability to be less than 1.1

RE: magnetic permeability 2.0

A perm of 1.1 or even 1.2 is fairly non-magnetic, 2.0 would be noticeably magnetic.
I would ask for some clarification.

RE: magnetic permeability 2.0

Materials with relative permeability from 1.00001 to 4.0 could be called feebly magnetic materials. a material having a permeability less than 1.05 is normally classified as paramagnetic (normally called nonmagnetic)

Thanks MagMike, MagBen, and EdStainless. This helps considerably.

RE: magnetic permeability 2.0

the permeability value is calculated with some standard like air. if the material permeability value should be greater than the permeability value of air it should be magnetised (ferromagnetic).. if the material permeability value less than the permeability value of the permeability value of air we called as non-magnetic(paramagnetic & diamagnetic). as per this statement the material what you describe is magnetic material. if you wanna more details you must share the residual magnetism value.
