Question

Which of the following alloys has copper as its constituent? a.Nichrome b. Chromium c. Zinc d.Brass

Answer 1

Hint: An alloy is an admixture of metals, or a metal combined with one or more other elements. For example, combining the metallic elements gold and copper produces red gold, gold and silver becomes white gold, and silver combined with copper produces sterling silver. Copper alloys are metal alloys that have copper as their principal component. They have high resistance against corrosion.

Complete answer:
Brass has copper as its constituent . Brass is an alloy of copper and zinc. The combination of these metals makes the brass solid and robust. The door buttons and high-quality locks are all made of brass. Brass alloy can have diverse amounts of zinc or other elements added. These differing mixtures produce a wide range of characteristics and variation in colour. Improved amounts of zinc contribute to the material with improved strength and ductility .

Note:
Copper alloys are metal alloys that have copper as their principal component. They have high resistance against corrosion. The best known traditional types are bronze, where tin is a significant addition, and brass, using zinc instead. Both of these are imprecise terms, having both been commonly referred to as lattens in the past. Today the term copper alloy tends to be substituted, especially by museums.
