About Alloy
Copper alloy C46400, also known as naval brass, is a high-strength brass alloy primarily composed of copper (Cu) with significant additions of zinc (Zn) and tin (Sn). It typically contains approximately 60% to 65% copper, 0.75% to 1.25% tin, and the remainder zinc, with small amounts of other elements such as lead (Pb) and iron (Fe). Naval brass C46400 is renowned for its excellent corrosion resistance in seawater and other aggressive environments, as well as its good machinability and weldability. It is commonly used in marine and industrial applications where resistance to corrosion, strength, and durability are crucial, such as in marine hardware, shipbuilding, and oil and gas equipment. The alloy's properties make it suitable for both structural and decorative purposes, combining practical functionality with aesthetic appeal in demanding marine environments.
