All of those qualities are relative. Aluminum is a good start. For formed sheet metal, type 5052-H32 is pretty common.
Besides a number of books published on Browning, and some of the gun collector forums (google Browning collectors) you might start with Browning. They have a website, and are still in business making very nice rifles, shotguns, and pistols.
To start you will need a piece of weatherproof sheet metal, assuming the sign will be outside. Depending on what size you have you may also need tin snips to cut the metal You will also need paint that can be used on metal outdoors to prevent rusting, screws to mount your sign and a drill.

If you buy a lot of sheet metal, whether you're involved in duct work, construction, repair or any other industry that involves a lot of sheet metal, then you need to find a good sheet metal supply company to strike up a working relationship with. Showing some customer loyalty can ultimately work out for the best when you've been buying from the same supplier for years on end, but of course, you don't want to get stuck with a company that could care less about your loyalty, so here's what to look for in a supplier.Quality MetalThis comes first and foremost, above all else. No matter how cheap they might be, whether or not they have customer loyalty programs to reward longtime buyers, the bottom line is quality. If they're giving you cheap, low-quality, inconsistent sheet metal, then what good is it to keep buying from them? If you get lousy product from a company the first time you buy from them, there's absolutely no reason to ever make a second purchase.PricePrice is important, but it's not the most important thing. Poorly made sheet metal is usually the cheapest, for instance, but that doesn't mean that the best sheet metal is the most expensive. Most sheet metal suppliers will offer deals on bulk purchases, for instance. Look for a company that offers fair prices on high quality sheet metal supply.Deals and ProgramsYou're looking for programs that reward longtime working relationships. A company that will cut you a discount, for instance, based on number and quantity of purchase. Once you find a sheet metal supplier that offers you great product at fair prices and with rewards for long time support, you have a supplier that most in your industry would love to find.They can be hard to find, of course, so you'll want to do some shopping around. If you have any colleagues or friends who work in sheet metal, you may want to start by asking them who their supplier is.
