Question

three composition of solder

Answer 1

Alloy:-

It is a homogeneous mixture or solid solution of two or more metals, in which the atoms of one replacing or occupying interstitial positions between the atoms of the other.

Solder:-

generally alloy of lead and tin.

basically used in soldering and used to join together metal work pieces and having a melting point below that of the work pieces.

Answer 2

Answer:

A higher tin composition gives the solder higher corrosion resistances, but raises the melting point. Another common composition is 11% tin, 37% lead, 42% bismuth, and 10% cadmium. This combination has a low melting point and is useful for soldering components that are sensitive to heat.
