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 such a parameter as the specific weight of nickel. Since this material is complex, it is not possible to calculate the specific weight of nickel in field conditions. This procedure is carried out in special chemical laboratories. However, the average specific weight is known and is 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. This material does not tarnish when exposed to air. The melting point of nickel is 1453 degrees Celsius, and its boiling point ranges from 2730 to 2915 degrees Celsius. 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 0.443 J/(K·mol)
• Molar volume is 6.6 cm³/mol
• Thermal conductivity is 90.9 W/(m·K)

The most stable oxidation state for nickel is +2. The resulting nickel oxide is a powerful oxidizing agent. This type of material has excellent corrosion resistance, including resistance to alkalis, water, acids and air. This property is provided by nickel’s ability to form a protective film. 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 burns in powder form, but not in other cases.

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.
