Specific weight of nickel, its properties, grades and table of values

Nickel is a chemical element of the fourth period and tenth group in the corresponding table of chemical elements. Simple nickel is a transition metal that is easy to forge, very ductile, and white with a silvery tint.

This element received its name because arsenic gas was released during ore smelting. In German mythology, this was the name of an evil spirit that gave miners nickel ore instead of copper.

Table of nickel specific weight

The weight of this material depends on the specific weight of nickel. For practical calculations, reference density values are usually used because the result depends on metal purity, temperature and the condition of the sample. The average specific weight of nickel is about 8.9 g/cm³.

To simplify calculations of such indicators as the weight of nickel and its specific weight, the table below provides these values, as well as other calculations for different measurement systems.

Properties of nickel

In compact form, nickel is very ductile and is easily processed by pressure forming. In air it is relatively stable because of a protective oxide film. The melting point of nickel is about 1455 °C, and its boiling point is about 2913 °C. Nickel belongs to the group of heavy metals.

Among the main properties, the following should be noted:

• Electrical resistivity is 0.0684 μΩ·m
• Material density is 8.902 g/cm³
• Atomic mass of the material is 58.69 u
• Specific heat capacity is about 0.443 kJ/(kg·K)
• Molar volume is 6.6 cm³/mol
• Thermal conductivity is 90.9 W/(m·K)

The most stable oxidation state for nickel is +2. Nickel has good corrosion resistance in air, water and alkaline media because it can form a protective film. Resistance to acids depends on conditions: nickel dissolves in hot concentrated sulfuric acid and in dilute nitric acid. When combined with carbon monoxide, it forms a highly toxic and volatile carbonyl. Nickel can burn in powder form; in compact form it usually does not burn.

Nickel grades

In modern industry, there are many different types of nickel. The main types include:

• Group N0 and N1. Primary nickel with a content of the material itself and cobalt of at least 99.3% and 99.93%, respectively. This type is produced in the form of strips, plates and sheets obtained by electrolysis.
• Group N2, N3 and N4. Primary nickel with a content of the material itself and cobalt of at least 99.8%, 99.93% and 99.93%, respectively. This type is produced in the form of granules, plates, cuttings, strips, ingots and cathode sheets obtained by remelting, fire refining, pressing and electrolysis.
• Group NP1, NP2, NP3 and NP4. Semi-finished nickel with a content of the material itself and cobalt of at least 99.99%, 99.5%, 99.3% and 99%, respectively. This type is produced in the form of rods, strips, sheets, wire and tapes.
• Group NPA1 and NPA2. Anode semi-finished nickel with a content of the material itself and cobalt of at least 99.7% and 99%, respectively.
• Group NPAN. Non-passivating anode semi-finished nickel with a content of the material itself and cobalt of at least 99.4%, produced as items such as rods and sheets. This group is characterized by the absence of a high-resistance film.
• Group NK0 and NK2. Silicon nickel with a content of the material itself and cobalt of at least 99.4%. It is produced only as wire.
• Group NMts1, NMts2, NMts2.5 and NMts5. Manganese nickel with a content of the material itself and cobalt of at least 98.5%. It is produced only as wire.
