Aug 12, 2018· Pure iron is too soft and reactive to be of much real use, so most of the "iron" we tend to use for everyday purposes is actually in the form of iron alloys: iron mixed with other elements (especially carbon) to make stronger, more resilient forms of the metal including steel. Broadly speaking, steel is an alloy of iron that contains up to ...

The specific gravity of all other materials are compared to water as a fraction heavier or fraction lighter density, no matter how small or large the fraction is. For example, beryllium has a specific gravity (sg) of (1840 kg/m³). As specific gravity is just a comparison, it can be applied across any units.
Hardness: 5 6 Comments: The iron and titanium oxide mineral ilmenite is present in small amounts in many igneous rocks and placer sands and is the principal titanium ore. Ilmenite forms iron black, thick tabular or acute rhombohedral crystals (hexagonal system), as well as thin plates, compact masses and embedded grains.
