# Overview of Heating Materials

| The diagram shows the temperature range and the resistivity of typical materials for heating elements.
|  | Do not forget that humble 1500 oC (roughly the melting point of iron) means that it is really hot! Mankind had to invent pretty tricky crafts for about 2000 years because nobody could reach the melting point of iron.
|  | Beyond 2000 oC there are not many usable materials left. Essentially you are stuck with graphite (not in the figure).
