The alloy called brass is composed of
A{'text': 'Copper and zinc', 'label': 'A'}
B{'text': 'Copper and tin', 'label': 'B'}
C{'text': 'Iron and carbon', 'label': 'C'}
D{'text': 'Aluminium and copper', 'label': 'D'}
Answer & Solution
Correct answer: A. {'text': 'Copper and zinc', 'label': 'A'}
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.
