Answer:
Solder is a metal alloy usually made of tin and lead which is melted using a hot iron.
Explanation:
33% Pb and 67% Sn
Old-fashioned solders contain a mixture of tin (50-70%), lead (30-50%), copper, antimony, and other metals. Newer solders dispense with lead for health reasons. A typical modern solder has 99.25 percent tin and 0.75 percent copper
