What is the main component ratio of yellow brass?

Yellow brass is primarily composed of copper and zinc, and the most common composition is 66% copper and 34% zinc. This specific ratio of copper to zinc provides yellow brass with its characteristic properties, such as good corrosion resistance, excellent malleability, and strength.

The higher copper content ensures better ductility, allowing the metal to be easily shaped without breaking. The zinc not only aids in enhancing its mechanical properties but also influences the coloration, resulting in the distinct yellow hue associated with brass.

While other compositions exist, sometimes used in specific applications or variations of brass, the 66% copper and 34% zinc ratio is the standard for yellow brass. This choice strikes a balance between strength, corrosion resistance, and workability, making it suitable for plumbing fittings and other applications.
