Question

Identify the entirely correct matching of the following historically named metallurgical alloys with their primary constituent metals: (I) Bronze, (II) Brass, (III) Invar, (IV) Constantan.

Answer: A

💡 Solution & Explanation

Bronze is fundamentally Copper + Tin (Cu+Sn). Brass is Copper + Zinc (Cu+Zn). Invar is an alloy of Iron + Nickel (Fe+Ni, ~36% Ni) prized for its near-zero thermal expansion. Constantan is an alloy of Copper + Nickel (Cu+Ni, 60/40) used for electrical resistance wires.
