Copper: It is a very good conductor of heat an electricity, it is highly resistan to corrosion and it is very ductile and malleable, and easy to solder.
Tin: It is very ductible and malleable when cold and it is very easy to work with and to melt, it is used as a filler metal for soft soldering.
Aluminium: It is very light, resistant to corrosion, good conductor of heat and electricity, non-toxic, so it is used in food packaging, very ductible and malleable and easy to shape.
Zinc: It is malleable and ductile, good conductor of heat and electricity and highly resistant to corrosion and rust.
