What is: Nickel, nickel iron, nickel pig iron, nickel-based alloys

1.Nickel is a transition metal element with the element symbol Ni, located in Group VIII of the fourth cycle, and the atomic number is 28. Nickel is mainly used in steel, nickel-based alloys, electroplating and batteries, and is widely used in various military manufacturing industries such as aircraft and radar, civil machinery manufacturing and electroplating industries. Nickel is one of the important raw materials for stainless steel. The nickel consumption in China's stainless steel industry accounts for more than 80% of primary nickel consumption and output, and the global share is more than 2/3.

2.Ferronickel An alloy of iron and nickel obtained from oxide ores or other nickel-containing materials, with a nickel content of greater than or equal to 15% (mass fraction) and less than 80% (mass fraction). According to the national standard GB/T25049-2010, ferronickel can be divided into five categories: low carbon ferronickel, low carbon low phosphorus ferronickel, medium carbon ferronickel, medium carbon low phosphorus ferronickel, and high carbon ferronickel.

3.Nickel Pig Iron The nickel content of nickel pig iron is less than 15%. Generally, according to the different nickel content in nickel pig iron, it can be divided into high-grade nickel pig iron (10% and above), medium-grade nickel pig iron (4-9%), and low-grade nickel pig iron. Nickel pig iron is mainly smelted in submerged arc furnaces and blast furnaces. Generally, submerged arc furnaces produce high-grade nickel pig iron, and blast furnaces produce medium-low-grade nickel pig iron. Nickel pig iron is an important source of nickel raw material for stainless steel.

4.Nickel-based Alloy Nickel-based alloys refer to alloys based on nickel (containing nickel content ≥50%) and containing elements such as Cr, Mo, Cu, Al, Ti, Nb, etc. According to the main properties, they are subdivided into nickel-based heat-resistant alloys, nickel-based corrosion-resistant alloys, nickel-based wear-resistant alloys, nickel-based precision alloys and nickel-based shape memory alloys. For example, Inconel 690, Hatselloy C-276, Haynes 242, Monel 400, Incoloy800 and other nickel-based alloy grades.
