Question

Which of the following alloys contains a non-metal as one of the constituents?

Options

• brass

• amalgam

• steel

• bronze

Answer 1

Steel

Explanation:

Steel is an interstitial alloy created by combining the metal iron (Fe) with a small percentage of the non-metal carbon (C). The carbon atoms fit inside the spaces between the iron atoms, making the final material incredibly strong. The remaining options are incorrect because brass consists solely of copper and zinc, bronze is made from copper and tin, and amalgams are mixtures of mercury with other metals.
