Nickel, a versatile metal known for its resistance to corrosion and ability to alloy with many other metals, is crucial in various industrial applications. If you’re working with nickel or simply curious about its properties, understanding its density is important. Let’s dive into what density is, why it matters, and the specific details about nickel.
What is the Density of Nickel Metal?
Nickel is a transition metal with the chemical symbol Ni and atomic number 28. It has a standard density of approximately 8.907 grams per cubic centimeter (g/cm³) at room temperature (20°C or 68°F). This density indicates that nickel is relatively dense compared to many other metals, which influences its physical properties and applications.
Density of Nickel kg/m³
The density of nickel metal is approximately 8,907 kilograms per cubic meter (kg/m³).
Density of Nickel lb/in³
The density of nickel metal is approximately 0.323 pounds per cubic inch (lb/in³).
Measurement and Calculation of Nickel Density
To measure the density of nickel metal accurately, one can use various methods. One common approach involves using the Archimedes’ principle, which involves measuring the volume of water displaced by the metal. Another method is using density calculation formulas where mass and volume are measured directly.
What is the Density of Nickel at 20 Degrees Celsius?
At 20 degrees Celsius (68 degrees Fahrenheit), the density of nickel is approximately 8.908 grams per cubic centimeter (g/cm³). This value is based on the metal’s standard density, as it changes only slightly with temperature variations.
Nickel Density: Comparative Analysis with Other Metals
When comparing nickel to other metals, its density provides insight into its relative weight and strength characteristics. For instance, nickel is denser than aluminum density (2.70 g/cm³) and titanium density (4.506 g/cm³), which makes it heavier but also potentially more robust in certain applications. This density comparison is valuable when selecting materials for specific uses, such as structural components where weight and strength are crucial.
Nickel’s density is lower than that of metals like lead density (11.35 g/cm³) and tungsten density (19.3 g/cm³), which are much denser and used in applications requiring significant mass or high shielding properties. Conversely, nickel’s relatively high density compared to lighter metals helps it provide the necessary strength and durability in demanding environments.
Factors Affecting Nickel’s Density
Several factors can influence the density of nickel metal, including temperature and alloy composition:
Temperature
Nickel’s density is affected by temperature changes. As temperature increases, the metal expands slightly, which results in a minor decrease in density. Conversely, cooling nickel causes it to contract, slightly increasing its density.
Alloy Composition
Nickel is often used in alloys, such as stainless steel, which can alter its effective density. The presence of other elements in an alloy can modify the density of the overall material. For instance, stainless steel, which contains nickel, chromium, and other elements, will have a different density compared to pure nickel.
Purity of the Metal
Pure nickel has a consistent density of around 8.907 g/cm³. However, in practical applications, nickel is often alloyed with other metals, which can alter its density. High-purity nickel, typically used in precision applications, maintains a density close to the standard value of 8.907 g/cm³.
Applications of Nickel
Nickel is a versatile metal with a wide range of applications due to its unique properties, including high strength, corrosion resistance, and magnetic characteristics. Here are some key applications of nickel:
Stainless Steel Production
Nickel is a crucial alloying element in stainless steel, which typically contains 8-12% nickel. The addition of nickel enhances the steel’s resistance to corrosion and oxidation, making it ideal for use in kitchen utensils, cutlery, industrial equipment, and construction materials.
Battery Manufacturing
Nickel is used in various battery technologies, including nickel-cadmium (NiCd), nickel-metal hydride (NiMH), and lithium-ion batteries. Its high energy density and ability to maintain performance across a range of temperatures make it suitable for use in rechargeable batteries for electronics, electric vehicles, and power tools.
Electronics and Electrical Components
Nickel’s magnetic properties and corrosion resistance make it valuable in the electronics industry. It is used in connectors, switches, and other electronic components. Nickel plating is also applied to improve the conductivity and durability of electrical contacts.
Aerospace and Defense
In aerospace and defense applications, nickel alloys are used for their high strength, resistance to heat, and ability to withstand extreme conditions. Nickel-based superalloys are employed in turbine engines, rocket nozzles, and other critical components that operate under high temperatures and pressures.
Marine Applications
Nickel-containing alloys are used in marine environments to resist corrosion from seawater. These alloys are used in shipbuilding, offshore platforms, and other marine equipment to ensure longevity and reliability in challenging conditions.
Challenges in Machining Nickel
Machining nickel presents several challenges due to its physical and chemical properties. Understanding these challenges is essential for achieving high-quality results:
- Work Hardening: Nickel has a tendency to work harden rapidly. This means that the material becomes harder and stronger as it is being machined, which can lead to increased tool wear and difficulty in maintaining precision.
- High Cutting Forces: The toughness and strength of nickel require higher cutting forces compared to other materials. This can result in more significant stress on the machining equipment and tools, necessitating robust and high-performance machinery.
- Thermal Conductivity: Nickel’s thermal conductivity is relatively low, which can cause heat to build up during machining. Effective cooling strategies are essential to prevent overheating, tool damage, and thermal deformation of the workpiece.

FAQ
At 25 degrees Celsius (77 degrees Fahrenheit), the density of nickel is approximately 8.907 grams per cubic centimeter (g/cm³). The density of nickel changes minimally with temperature, so the density at 25°C is very close to its value at 20°C.
The density of nickel oxide (NiO) is approximately 6.67 grams per cubic centimeter (g/cm³). Nickel oxide is a compound of nickel and oxygen, and its density is significantly lower than that of pure nickel metal due to the difference in atomic masses and the structure of the compound.
Nickel electroplating current densities range from 2 to 10 A/dm² for decorative finishes and 5 to 30 A/dm² for engineering applications, influencing the thickness and quality of the deposit.
The density of electroless nickel typically ranges from approximately 8.1 to 8.6 grams per cubic centimeter (g/cm³). The exact density can vary based on the specific formulation and properties of the electroless nickel deposit.
