UNS C46400 Copper Alloy Chemical Composition, Grades, Chart and Document

Uns C46400 is a very resistant copper alloy which properties are providing it with an excellent corrosion resistance, suitable for marine environments and industrial applications. As a copper-based alloy containing 60% copper, 39.2% zinc and 0.8% tin, it shows superior mechanical features along with excellent machinability and soldering facility. This copper based alloy which is referred as Naval Brass is widely employed for items such as marine hardware, fasteners, valves and pump components. Its grades must be made by an operation that adheres to the strict standards of the ASTM, producing consistent quality and credibility. The chemical composition chart outlines its elemental composition, while accompanying documents explain mechanical properties, usage, and more of the material. The combination of its strong enough nature and corrosion resistance ability perfectly suitable for use in the places where the most demanding machines are built.

UNS C46400 Copper Alloy Chemical Composition And Grade Table

UNS C46400 belongs to the family of naval brasses and is a material made of copper (60-63%) and zinc (38-41%) with a minor amount of tin (0.5-1.0%). This compound has excellent resistant nature towards corrosion in the marine environment, therefore, it is suitable for use in, among other things, marine hardware, valves, pumps, and fittings. It provides high tensile strength and good machinability that make its use even more suitable. C46400 complies with both ASTM B21/B21M and ASTM B124/B124M standards, which guarantee the regularity and the production performance. Balanced in chemical composition and being reliable, it is opted for in a great number of sea and industrial uses.
