They don't. The Earth's crust is composed mostly of silicate minerals. The core is believed to be metal based on the behavior of seismic waves passing through it. The density of the core is consistent with iron and nickel.
Aluminium.
Iron , Aluminium and Copper Can Be Found , Also Gold Can Be Found Uncombined in the Earths Crust .
Aluminum is the Earths most abundant metal and its located in the Earths outer crust.One of the properties of crust is that it consists of a variety of sedimentary,metamorphic and igneous rocks.
The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma. At the center of the Earth is a hot, dense metal core.
Oxygen is the most abundant element in the earth's crust and is not in the boron family. Aluminum is in the boron family and is the third most abundant element in the earth's crust. Refer to the related link for a list of the 10 most abundant elements in the earth's crust and their percentages.

Aluminium.
No one invented metal. Metals are naturally occurring elements in the earths crust (and core)

The most abundant metal in the earth crust is aluminium.
The boron family member is boron (B). The most abundant metal in Earth's crust is aluminum (Al).
They began as minerals inside earths crust
The most common chemical elements in the crust are oxygen (46.6%), silicon (27.7), aluminum (8.1), iron (5.0), calcium (3.6), potassium (2.8), sodium (2.6), and magnesium (2.1).Oxygen is a non-metal and silicon is a metalloid - so the most common metal is aluminum.
Metal comes from Earths crust ,so if we dont reuse it ,we might run out of it some day
