What is the composition of naval brass?
Naval brass is the classic marine, high-strength and corrosion-resistant alloy containing 60 percent copper, . 75 percent tin and 39.2 percent zinc. 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.
What metals is brass made of?
brass, alloy of copper and zinc, of historical and enduring importance because of its hardness and workability. The earliest brass, called calamine brass, dates to Neolithic times; it was probably made by reduction of mixtures of zinc ores and copper ores.
