Element Technica Bridgeplate - does anyone know what material they're made from?

[James Darren]

Blast from the past - but does anyone know what material the old Element Technica bridgeplate is made from?

I'm assuming aluminum but perhaps someone knows for certain.

Thanks in advance....

What about the screws & lever? I'm trying to figure out how resistant it would be to corrosion/rust if I submerse it (long story)
