Titanium is useful for constructing rocket-powered vehicles due to its absurdly low mass for its strength (though iron is better for space stations and bases). It can be found in Lunar Ilmenite ore. Philip Eklund suggests that "foamed" titanium will be used in space habitats as a low-mass construction material, he calls it "space wood."

α-iron, also known as ferrite, is the most stable form of iron at normal temperatures. It is a fairly soft metal that can dissolve only a small concentration of carbon (no more than 0.021% by mass at 910 °C).

So it is accurate to say that molten iron contains heat. How hot does it have to be to smelt iron? Iron melts at 1800°C (3270°F) and gold melts at 1062°C (1943°F). Because iron has a higher melting temperature than gold we hope that even with our limited resources we can get a furnace originally used to smelt iron to work our gold.
