Have you ever wondered about the fascinating world of metal densities? In this blog post, we’ll dive into the importance of understanding metal densities for mechanical engineers. As an experienced writer in the field, I’ll share insights on how density affects product weight estimation and provide a handy reference table for commonly used metals. Get ready to expand your knowledge and discover the secrets behind this crucial material property!
The mass of a certain substance per unit volume is referred to as the density of that substance, represented by the symbol “ρ”.
The formula for density is: P=m/v.
This expression is known as the definition of density, meaning the ratio of the object’s mass (m) to its volume (v), referred to as the density (ρ) of the material composing the object.
Engineers frequently need to utilize the property of density during the process of estimating product weight. We provide a reference table for the density of some commonly used metals:

Understanding the conversion of metal density units is essential for accurate calculations and material selection in engineering and industrial applications. Density, defined as mass per unit volume, is commonly expressed in various units, including grams per cubic centimeter (g/cm³), kilograms per cubic meter (kg/m³), and pounds per cubic foot (lb/ft³).
Density plays a crucial role in various practical applications. In engineering design, accurate density values ensure the correct material specifications for structural integrity. In manufacturing, density calculations help in determining material requirements and costs. Quality control processes also rely on density measurements to verify material properties against standards.
This unit is often used in laboratory settings and for small-scale applications. It expresses the density of a material as the number of grams in one cubic centimeter.
Widely used in engineering and construction, this unit expresses the density of a material as the number of kilograms in one cubic meter. It is particularly useful for large-scale applications and bulk material assessments.
Commonly used in the United States, this unit measures the density of a material as the number of pounds in one cubic foot. It is frequently used in construction, manufacturing, and other practical applications.
Converting between different units of density requires specific conversion factors. These factors are based on the relationships between the units of mass and volume involved. Understanding these relationships helps in applying the correct conversion factors.

Below are answers to some frequently asked questions:
The density of aluminum is approximately 2.70 grams per cubic centimeter (g/cm³) or 2,700 kilograms per cubic meter (kg/m³). This value is for pure aluminum, and it is a critical parameter in various industrial and engineering applications due to aluminum’s desirable properties, such as its strength-to-weight ratio. Aluminum alloys, which include other elements like copper, magnesium, manganese, silicon, and zinc, can have slightly different densities. For example, Aluminum Alloy 6061 also has a density of around 2.70 g/cm³, while Aluminum Alloy 7075 has a density of about 2.81 g/cm³. The low density of aluminum compared to other metals like steel makes it particularly useful in aerospace, automotive, and construction industries where weight savings are important.
To convert metal density from grams per cubic centimeter (g/cm³) to kilograms per cubic meter (kg/m³), you can use a simple multiplication factor. Since 1 gram is equal to 0.001 kilograms and 1 cubic centimeter is equal to ( \frac{1}{1,000,000} ) cubic meters, the conversion factor is 1000. This means that the density in kg/m³ is 1000 times the density in g/cm³.
The formula to perform this conversion is:
For example:
If the density of a metal is 2.7 g/cm³, then in kg/m³, it would be:
This straightforward multiplication allows for quick and accurate conversion between these units, which is particularly useful when dealing with metal density charts in various engineering and scientific applications.
Metal density is a crucial factor in engineering due to its significant impact on material selection, design, and overall performance of products. Density affects several key aspects:
In summary, metal density is a fundamental property that influences material selection, design considerations, and the economic and environmental impact of engineering projects. It is vital for achieving the desired balance between performance, cost, and sustainability in various applications.
The densities of common alloys like brass and steel can vary depending on their specific composition. For brass, the density generally ranges around 8.5 g/cm³ or 8,500 kg/m³, with variations such as Brass 60/40 having a slightly higher density of 8.52 g/cm³ or 8,520 kg/m³, and Red Brass approximately 8.75 g/cm³ or 8,720 kg/m³. Steel also shows variations in density: general steel typically has a density of about 7.80-7.86 g/cm³ or 7,800-7,860 kg/m³, mild steel is around 7.85 g/cm³ or 7,850 kg/m³, and stainless steel ranges from 7.48-7.95 g/cm³ or 7,480-7,950 kg/m³. These densities are essential for various applications, including engineering and manufacturing, as they influence the material’s strength, weight, and suitability for different uses.
The density of steel is usually 7.8 g/cm3.
The density of gray cast iron is 6.6 ~ 7.4 g/cm3;
The density of white cast iron is 7.4 ~ 7.72 g/cm3;
The density of malleable cast iron is 7.2 ~ 7.43 g/cm3;
The density of cast steel is 7.8 g/cm3;
The density of industrial pure iron is 7.8759 g/cm3.
What is the density of copper?
Copper is a transition metal and is represented by the chemical symbol “Cu”.
There are several classifications of copper, including pure copper, brass, and bronze. Pure copper, also known as “red copper”, is defined as copper with a copper content of 99.5-99.95%.
There are three subtypes of pure copper, which include oxygen-free copper, oxygen copper, and special copper.
Brass is an alloy made from copper and zinc. White copper, on the other hand, is an alloy of copper and nickel, which is characterized by its silver-white appearance and metallic luster.
Bronze is a term originally used to describe a copper-tin alloy, but it has since been extended to encompass all copper alloys other than brass and white copper.
The density of copper varies depending on the type of copper. The density of copper is defined as the ratio of its mass to its volume.
Formula for copper density:
The density of different copper is different, but it can be roughly divided into the following types:
The steel density calculation formula is: ρ= m/V。
Density unit: the international unit is kg/m3, and the common unit in the experiment is g/cm3, 1g/cm3 = 103kg/m3.
The density of steel is 7.8 g/cm3;
The weight of iron can be determined using Archimedes’ principle.
To do this, first, suspend the iron block from a thin rope and measure its true weight, “G,” using a spring scale.
Next, fully immerse the iron block in water and measure its apparent weight, “G’,” by using the spring scale while it is in the water.
Finally, by calculating the weight of iron via the formula ρ=Gρwater/(G-G’), you will get the result that the density of steel is 7.8 g/cm3 or 0.28 lb/in3.
