Aluminum is usually easier for most to work with with simple hand tools.
Steel is fine but it might rust and look bad after a while. Make the

work with . Electrically there will be little if any differance.


And of course, everyone did use steel (once things progressed beyond
wood and bakelite chassis) right up until aluminum because readily
available and/or cheap enough, at which point I doubt anyone used
steel except if what they were building was really really heavy, ie
a kilowatt modulator or final.
