The main reason for adding nickel in ferrous alloys is to promote an austenitic microstructure. Nickel generally increases ductility, toughness and corrosion resistance." [19] Nickel pig iron is distinguished from ferronickel by the former's low weight fraction (4–10%) of nickel and high carbon content (>3%). In contrast, ferronickel is a ...
The adjective ferrous or the prefix ferro-is often used to specify such compounds, as in ferrous chloride for iron(II) chloride (FeCl 2). The adjective ferric is used instead for iron(III) salts, containing the cation Fe 3+. The word ferrous is derived from the Latin word ferrum, meaning "iron".

An alloy is distinct from an impure metal in that, with an alloy, the added elements are well controlled to produce desirable properties, while impure metals such as wrought iron are less controlled, but are often considered useful. Alloys are made by mixing two or more elements, at least one of which is a metal.
Ferrous metallurgy is the metallurgy of iron and its alloys. The earliest surviving prehistoric iron artifacts, from the 4th millennium BC in Egypt , [ 1 ] were made from meteoritic iron-nickel . [ 2 ]
The term "ferrous" is derived from the Latin word meaning "containing iron". This can include pure iron, such as wrought iron, or an alloy such as steel. Ferrous metals are often magnetic, but not exclusively. Non-ferrous metals and alloys lack appreciable amounts of iron.
Researches created an alloy with the strength of steel and the lightness of titanium alloy. It combined iron, aluminum, carbon, manganese, and nickel. The other ingredient was uniformly distributed nanometer-sized B2 intermetallic (two metals with equal numbers of atoms) particles. The use of nickel team avoided problems with earlier attempts ...
The family includes Kovar, FerNiCo I, FerNiCo II, and Dumet. The name is made up of the chemical symbols of its constituent three elements. "Dumet" is a portmanteau of "dual" and "metal," because it is a heterogeneous alloy, usually fabricated in the form of a wire with an alloy core and a copper cladding. These alloys possess the properties of ...
