About Alloy
Copper alloy C26000, also known as cartridge brass, is a versatile brass alloy primarily composed of copper (Cu) and zinc (Zn). It typically contains around 70% copper and 30% zinc, with small amounts of other elements such as lead (Pb) and tin (Sn). C26000 brass is valued for its excellent machinability, corrosion resistance, and attractive golden color. It is commonly used in various applications where these properties are advantageous, such as in plumbing fittings, valves, and components requiring good formability and aesthetics. The alloy is known for its ability to be easily fabricated into intricate shapes and its suitability for both decorative and functional purposes across industries like plumbing, architecture, and decorative arts.
