Ferroaluminum (FeAl) is a ferroalloy, consisting of iron and aluminium.The metal usually consists of 40% to 60% aluminium. Applications of ferroaluminum include the deoxidation of steel, [1] hardfacing applications, reducing agent, thermite reactions, AlNiCo magnets, and alloying additions to welding wires and fluxes.

A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.
Ferroalloy refers to various alloys of iron with a high proportion of one or more other elements such as manganese (Mn), aluminium (Al), or silicon (Si). [1] They are used in the production of steels and alloys.
Notes [ edit ] ^ The purity of gold alloys is expressed in karats , (UK: carats) which indicates the ratio of the minimum amount of gold (by mass ) over 24 parts total. 24 karat gold is fine gold (24/24 parts), and the engineering standard [ citation needed ] is that it be applied to alloys that have been refined to 99.9% or better purity ("3 ...
The characteristic properties of elemental metals and nonmetals are quite distinct, as shown in the table below. Metalloids, straddling the metal-nonmetal border , are mostly distinct from either, but in a few properties resemble one or the other, as shown in the shading of the metalloid column below and summarized in the small table at the top ...
Extraction and processing costs were lowered over technological progress and the scale of the economies. However, the need to exploit lower-grade poorer quality deposits and the use of fast increasing input costs (above all, energy) increased the net cost of aluminium; [111] the real price began to grow in the 1970s with the rise of energy cost ...
Aluminium–copper alloys (AlCu) are aluminium alloys that consist largely of aluminium (Al) and traces of copper (Cu) as the main alloying elements.Important grades also contain additives of magnesium, iron, nickel and silicon (AlCu(Mg, Fe, Ni, Si)), often manganese is also included to increase strength (see aluminium-manganese alloys).
7022 aluminium alloy is an alloy in the wrought aluminium-zinc family (7000 or 7xxx series). It is one of the more complex grades in the 7000 series, with at least 87.85% aluminium by weight.
