Magnetic Permeability of a Mechanical System

Magnetic Permeability of a Mechanical System

Magnetic Permeability of a Mechanical System

(OP)
Customer requests a magnetic permeability of below 2.0 for a material handling system. Prefer to use an aluminum structure with a carbon steel hydraulic actuator. Can anyone tell me how I can calculate/estimate the magnetic permeability of the entire system? Is it proportional to the mass of the different materials and their individual permeability? Thanks in advance.

RE: Magnetic Permeability of a Mechanical System

Permeability is a material property, I've never heard of calculating it for an entire system.  Aluminum will be fine but carbon steel will be 1000+.  I'd look for an austenitic stainless.  They will all be below 2 in a soft condition.

RE: Magnetic Permeability of a Mechanical System

What he means is that he wants everything in the system below 2.  Basically all non-ferromagnetic.  Al, austenitic SS, Ni alloys, Ti (don't laugh, it isn't that expensive any more), and most Cu alloys (brass and bronze) will fill the bill.

Nickel is ferromagnetic.

Most Ni alloys are not ferromagnetic.
