In class today Mr Andrews asked us to find out what an alloy is, what a solder is, and what "tinning refers to".
An alloy is: a metal made by combining two or more metallic elements, used to create greater strength and resistance.
A solder is: a low-melting alloy, Usually based on lead and tin, brass or silver, it is used for joining easily melting metals.
"Tinning" refers to: It is the preparation for soldering a stranded wire so there is a good joint.
