Alloys are homogeneous mixtures of a metal with a metal or nonmetal. Which among the following alloys contain non-metal as one of its constituents? (a) Brass (b) Bronze (c) Amalgam (d) Steel

Answer: (d) Steel

Steel is an alloy made up of carbon and iron where carbon is a non-metal.

Stainless steel alloy

Alloys are metal mixtures with other elements whose precise composition is determined by the properties needed. Alloys are metallic in nature, which means they have strong thermal and electrical conductivity.

  • Stainless steel is an alloy of iron, chromium and nickel.
  • Chromium, iron, silicon, manganese, carbon, and, in some cases, relatively significant quantities of molybdenum and nickel are known to be present in this alloy.
  • Chromium plays an important role in the production of stainless steel. It gives hardness to the stainless steel and makes it tough. It improves corrosion resistance, particularly at high temperatures.
  • Because of the interactions between the atmosphere and its alloying components, stainless steel is known to remain stainless and avoid rusting.
