Brass is primarily an alloy of which two components?

Brass is primarily an alloy made from copper and zinc. The addition of zinc to copper not only enhances its mechanical properties, such as strength and ductility, but also improves its corrosion resistance. This combination allows brass to be used in a variety of applications ranging from plumbing fittings and musical instruments to decorative items and electrical connectors.

Copper is the base metal that provides the bulk of the characteristics associated with brass, while zinc is added to improve specific properties and adjust the alloy's color, strength, and workability. The proportion of zinc can vary widely, leading to different grades of brass, each suited for particular tasks.

The other combinations listed, such as copper with aluminum, gold with silver, and nickel with lead, do not represent the primary composition of brass. While they may form other types of alloys or materials, they lack the defining characteristics that make brass what it is.
