Historio
The first iron used by humans is likely to have come from meteorites.
The oldest known iron objects used by humans are some beads of meteoric iron, made in Egypt in about 4000 BC.
The discovery of smelting around 3000 BC led to the start of the iron age around 1200 BC and the prominent use of iron for tools and weapons.

Aplikoj
Iron is used to manufacture steel and other alloys important in construction and manufacturing.
Iron is a vital constituent of plant and animal life and works as an oxygen carrier in hemoglobin.
Iron oxide mixed with aluminum powder can be ignited to create a thermite reaction, used in welding and purifying ores.
