The reason it's easy to bend tin foil is mainly how thin it is. Brass is harder than most metals, including copper and gold, and only a little softer than platinum and iron. As far as materials for camera construction go, any metal will be soft enough to dent easily, especially at its thinnest point. Steel or cast iron are the only metals that are somewhat hard, and that's only because they are an alloy of iron and carbon, carbon being a non-metal and the hardest material there is. | |
