Question

What is the melting point of iron and aluminium? How is iron melted?

Answer 1

MP of iron = $1,{538}^{\circ }C$
MP of aluminium = ${660.3}^{\circ }C$
Since iron has a very high melting point (~1500^\circ ~C) so whether it will melt or not will depend upon the core temperature of the flame being used for the purpose. For example a candle flame never exceeds ${1400}^{\circ }C$ so, iron won't melt with a candle flame. However and the oxy-acetalene flame has a much higher temperature and can easily melt iron. Also, it is dependent on heat transfer conditions and the size of the iron object being melted.
