Copper and zinc mixed together form which alloy?

• A. Brass
• B. Bronze
• C. Steel
• D. Alnico

Answer: (A)

Mixing copper with zinc creates brass, a copper–zinc alloy. Alloying blends elements to change properties like color, hardness, and malleability. Copper alone is soft and reddish-brown; adding zinc gives a yellowish hue and typically increases stiffness while preserving ductility. This combination is different from bronze (copper with tin), steel (iron with carbon and other elements), and Alnico (an aluminum–nickel–cobalt magnetic alloy). Brass is widely used for hardware, fittings, and decorative items because of its bright luster and workability.
