What is the copper content percentage in a brass fitting?

Brass is an alloy primarily composed of copper and zinc. The copper content in brass can vary depending on the specific type of brass and its intended application, but it is typically around 60% to 90%. The answer provided, which is 85%, reflects a common composition found in many brass fittings.

Brass fittings often use this proportion of copper because a higher copper content can enhance the material's strength, corrosion resistance, and overall durability, making it ideal for plumbing and other applications requiring reliable materials. Different brass compositions are used for various applications; for instance, the presence of more zinc in some types of brass can lower the copper percentage, affecting properties such as malleability and ductility.

In summary, the 85% copper content identified represents a widely accepted standard for brass fittings, ensuring a balance of strength and workability that suits most plumbing requirements.
