Difficulty: EasyAlloys: Classification, Compositions, Physical Properties, and Uses

Brass is an alloy widely utilized in making musical instruments, door handles, and decorative fittings due to its strength, acoustic properties, and resistance to corrosion. Which pair of metals constitutes brass?

  1. Copper and zincAnswer
  2. B
    Copper and tin
  3. C
    Lead and tin
  4. D
    Iron and carbon

Answer

Copper and zinc
Brass is an alloy specifically produced by melting together copper and zinc. The addition of zinc improves the mechanical strength and workability relative to pure copper.

Step-by-Step Solution

1
Identify the standard elemental composition of the specified metallic alloy.
Brass is a substitutional metallic alloy composed primarily of copper (Cu) and zinc (Zn).
Alloys are mixtures of metals or a metal with another element; brass specifically pairs copper as the primary metal with zinc.
