There is evidence that iron was known from before 5000 BC. [15] 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 [16] and the prominent use of iron for tools and weapons. [17]

Iron meteorites consist overwhelmingly of nickel-iron alloys. The metal taken from these meteorites is known as meteoric iron and was one of the earliest sources of usable iron available to humans. Iron was extracted from iron–nickel alloys, which comprise about 6% of all meteorites that fall on the Earth.
Later, as more malleable iron became widely used for shorter-range clubs, an even wider variety of clubs became available. Many of the clubs manufactured between 1901 and 1935 came from Scotland, [2] but more and more started coming from larger US manufacturers. These early clubs had hickory shafts and wrapped leather grips. To secure the joins ...
Iron forms various oxide and hydroxide compounds; the most common are iron(II,III) oxide (Fe 3 O 4), and iron(III) oxide (Fe 2 O 3). Iron(II) oxide also exists, though it is unstable at room temperature. Despite their names, they are actually all non-stoichiometric compounds whose compositions may vary. [67]
