"Here's a couple more ideas on containing signals in the box. First, have
plenty of closely spaced fasteners along the joints; not just in the
corners. Second, the thin copper desoldering braid makes a fairly good RF
gasket. 'Best with your project!"

I would not use desoldering braid. Copper reacts with aluminum. The
electrolysis will form aluminum oxide, which is an excellent insulator, and
the rf tight enclosure will no longer be secure. It could also cause
rectification, and allow external signals to mix, resulting in many spurious
signals.

Aluminum likes stainless steel, since the electric qualities are similar.
Aluminum and copper plus moisture will form a battery.
