  • The resulting alloy has different properties than the original elements altogether, like increased strength and hardness.
  • In these elements, the major component is covered by the metals only.

Solder alloy:

  • Solder is also an alloy that is made up of the Tin (Sn) and Lead(Pb).
  • In Solder alloy, the quantity of Tin and Lead is 60% and 40% respectively.
  • These both have a low melting point that's why used in the composition of Solder.

Therefore, Solder is an alloy of Lead (Pb) and Tin (Sn).
