Question

Bronze contains:
A. 10% tin and 90% copper
B. 60% copper and 20% nickel
C. 90% copper and 10% tin
D. 80% zinc and 20% copper

Answer 1

Hint: Alloy can be defined a combination of metals combined with one or more other elements. Alloys can be a solid solution of metals elements or a mixture of metallic phases. Some of the alloys are brass, solder, pewter, amalgam, bronze etc.

Complete step by step answer:
Bronze is an alloy, which is composed of copper and tin. There are three major types of bronze in construction and sculpture based on percent composition of copper and tin are as follows:
Statuary Bronze: It contains approximately 97% of copper and 2% of tin and 1% of zinc. This composition is closest to the true bronze composition.
Architectural Bronze: This type of bronze is more of leaded brass, which is composed of approximately 57% of copper and 40% of zinc and 3% of lead.
Commercial Bronze: This type of bronze contains approximately 90% of copper and 10% of zinc.
The alloy bronzes are strong, tough and ductile at all the temperature and do not lose their strength at high temperature. Bronzes are durable and malleable and melts at \(950^\circ {\rm{C}}\). It resists corrosion and a better conductor of heat and electricity.
The alloy, bronze consist of 90% of copper and 10% of tin
So, the correct answer is “Option A”.

Note:
 We need to memorize some features about alloys that are combinations of metals combined with one or more other elements. Alloys used in making aircraft parts, bells, propellers for ships, in making coins, musical instruments, in jewellery etc.
