Solder is an alloy of

Options

  1. ACu and Sn.
  2. BFe and Zn.
  3. CPb and Sn.
  4. DAg and Zn.

Correct answer

C. Pb and Sn.

Step-by-step solution

- Solder is a metal alloy usually made of tin and lead which is melted using a hot iron. - Alloys commonly used for electrical soldering are 60 / 40 Sn - Pb , which melts at 188^ C (370^ F ) , and 63 / 37 Sn - Pb used principally in electrical/electronic work. This mixture is a eutectic alloy of these metals, which: has the lowest melting point (183^ C . or .361^ F ) of all the tin-lead alloys - The solder composition, being free of lead and other known toxic metals, has a composition range of 0.5 - 4.0% antimony,
