Did plenty of safety wiring during my years as a B-1 bomber crew chief. I don't miss it! It does work great when done correctly.
"Regular" is normally "304 stainless". "Inconel" used in the "hot areas", and not the preferred elsewhere. Just my experience! Former F-4 Engine weenie here!
I learned to safety wire at Boeing. After I got laid off I kept the pliers they issued me. Harbor Freight has the identical pliers.
