So aluminum is non magnetic as is alumina.
One is a conductor and one is an insulator.
My question is if alumina is exposed to high magnetic fields (rotating specifically) will an eddy current and thus heat get introduced into the ceramic?
I am looking for a light weight stiff substrate for rapid positioning and speed control of a large ultra lightweight servo.
Regular PCB material would work but I was wondering about alumina ceramics due some requirements of the structure.
And I have considered Kevlar and other non metallic substrates but alumina is better at reflecting heat.
Thanks
