alleryThe alloy called brass is composed of
ACopper and zinc
BCopper and tin
CIron and carbon

Answer & Solution
Correct answer: A. Copper and zinc
1. Alloys are homogeneous mixtures of two or more metals (or a metal and a non-metal).
2. Brass = Copper + Zinc (approx 70% Cu, 30% Zn).
3. Bronze = Copper + Tin.
4. Steel = Iron + Carbon; Duralumin = Al + Cu + Mg + Mn.
