Linear thermal expansion (α):
Iron - 11,8.10-6/°C
Aluminium - 23,1.10-6/°C
Copper - 17.10-6/°C
Brass - 19.10-6/°C

Aluminium is a better conductor than brass, it heats up first! We did it in a science experiment, you can trust this answer!!
Usually brass.
Brass is an alloy of copper and zinc.
Brass is mainly an alloy of copper and zinc. Some alloys do have small amounts of arsenic added also.
Brass is not mined. It is a synthetic alloy of copper and zinc.
Even though brass is a copper alloy, generally made up of about 95% copper and 5% zinc, copper is a softer metal. Copper has a higher heat capacity though, meaning than brass heats up more quickly than copper.
Brass is the odd one out among aluminium, brass, copper, and iron. Brass is an alloy while the other three are elements.
Yes...brass expands more than iron because brass is a mixture of metal which would expand more when heated..while iron is one metal which is harder to be able to expand. :)

Aluminium wire has produced problems due to unequal expansion/contraction at the brass or copper terminals and long-term surface oxidation. For that reason copper is recommended and there is usually no good reason not to use copper (of the correct gauge for the current).

Copper is cheaper than brass.

Both brass and copper are conductors.
