Which property of tin makes it suitable for use in solder?
-
A.
High density
-
B.
High electrical conductivity
-
C.
Corrosion resistance
-
D.
Low melting point
Correct Answer:
D. Low melting point
Explanation:
Tin is a primary component of solder because it possesses a relatively low melting point of approximately 232°C. When alloyed with other metals like lead, this melting point can drop even further, allowing the solder to liquefy easily at temperatures that will not damage heat-sensitive electronic components. This property ensures that the solder can be melted with a standard soldering iron to create secure electrical and mechanical bonds.
