Gunmetal alloys contain roughly 88% copper, 8-10% tin, and 2-4% zinc. Lead can be added for ease of machining or for bearing alloys. "Naval brass", for use in seawater, contains 40% zinc but also 1% tin. Brass is a mixture of copper and zinc, which has a harder finish than copper alone. We supply brass to customers for a variety of applications due to its durability and looks.
