Forum Technical Discussions MPI: Aluminum vs copper central conductors Posted by: ndtman , E-mail: Address, on July 08, 2008 at 15:12 : I have a requirement to circularly magnetize a hollow shaft (approx. 10 ft. long) using a rod at 7500 amps. The procedure does not allow the use of flexible cable. I intend to use a 2 inch diameter (12 ft long) copper rod as a central conductor but it is very expensive. Could I use a 2 inch diameter aluminum rod in place of the copper rod? Will the flux density at the surface of the part be the same as the copper conductor?
