I’m upgrading my avionics a bit and as a result need to replace a small section of my modular panel. It doesn’t look like I have anything in my scrap bin that fits the bill, so will have to buy a small sheet and get it cut to size. Does someone know what alloy of aluminum is typically used for instrument panels? 6061T6? Maybe it won’t really matter but I would like the new piece to match the existing panel as close as possible. Thanks in advance.
