Question

The alloy in which copper is a component is:
A) Bronze
B) Steel
C) Solder
D) Nichrome

Answer 1

Hint: To answer this question we need to know the combination of metals used to make these alloys. For this question we need to have the knowledge of the alloys. Alloys are the combination of one or more elements.

Complete step by step answer:
> First let’s understand what an alloy is. An alloy is a combination of metals or metals combined with one or more other elements. For example, the combination of metallic elements gold and copper we get red gold, combining gold and silver we get white gold and silver and copper produces sterling silver. Elemental iron combined with non-metallic carbon or silicon produces steel or silicon steel. To answer this question we need to know the combination of elements that are used to form the alloy. Now let’s see the components of these alloys.
> Bronze is made by the combination of copper with about 12.5 to 12.5 % tin and often with the addition of other metals such as aluminium, manganese, nickel or zinc. Also sometimes some non-metals are also added like arsenic, phosphorus and silicon. These addition of different metals and non-metals produces alloys having different properties like stiffness, ductility or machinability.
> Steel is of two types: low alloy steels and high alloy steels. The alloy steel refers commonly to low alloy steels. The simplest alloy steel is made from iron (Fe) and carbon (C) and some other elements can also be added such as vanadium, silicon, nickel, manganese, copper and chromium.
> Solder is used for soldering where it is melted to join metallic surfaces. It is made of tin and lead which is melted using hot iron.
> Nichrome: Nichrome alloy is made of nickel, chromium, iron and sometimes other elements.
From the above data on the given alloys we get to know that copper is used only in bronze alloy.

Therefore our answer is option A.

Note: We should have the knowledge of all the components used in any alloy. Having the information we can solve such direct questions with ease.
