In a Kenwood receiver. It is steel, not aluminum.
What is its purpose ?

Notice the blue and black pair of wires that are carefully routed
around the shield. My guess(tm) is that they carry AC power from the
xformer partly obscured at the top of the photo. Also note that both
ends of the steel shield are at chassis ground through mounting
screws. The steel shield possibly provides some reduction in 60 Hz
(hummmmm) coupling to the power supply filter caps. Later revisions,
that didn't have the shield probably re-routed the AC wiring.
