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.
