Naval Brass refers to a copper alloy of around 59% Copper 40% Zinc and 1% Tin with a trace amount of Lead. It is widely used in marine construction where strong, corrosive-resistant and hard material is required and is suitable for both salt and fresh water applications. Naval brass is used in propeller shafts, marine hardware, decorative fittings, shafting, propeller shafts and turn buckles. There are also many industrial applications, such as welding rods, condenser plates, structural uses, valve stems, balls, heat exchanger tubes, aircraft turnbuckle barrels, dies, and many more.
