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.

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.

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.
