Density Table of Metals and Alloys (Iron, Steel, Brass, Aluminum)

What is a density table?

A density table is a table that displays the density of a substance in the form of a table.

Density is a physical quantity with the symbol ρ.

We usually use density to describe the mass of a substance at a unit volume.

This concept is also frequently used in other natural sciences such as chemistry and materials science.

Features of density

Density reflects a property of the substance itself, which can therefore be influenced by external factors.

In general, the main physical quantities that affect the density of a substance are pressure and temperature.

Gas density is more affected by pressure and temperature.

Usually, the gas-only gives the density under standard conditions or at normal temperature and pressure.

Densities in other conditions can be calculated from the equation of the state of the gas (eg, the ideal gas state equation or the van der Waals equation).

The density of a liquid depends primarily on the composition of the liquid and is less affected by temperature (but sometimes it cannot be ignored).

High pressures can also have a significant impact.

The density of a solid varies with temperature and pressure and is similar to a liquid and is generally less pronounced.

FAQs about metal density

What is the density of steel and iron?

The density of steel is usually 7.8 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 brass?

What is the density of copper?

The chemical symbol of copper is Cu, which is a transition metal.

There are many classifications of copper.

If the copper content reaches 99.5-99.95%, it is pure copper.

Pure copper is also called “red copper”, which is generally divided into oxygen free copper, oxygen copper and special copper.

If it is an alloy of copper and zinc, it is brass.

The copper base alloy with nickel as the main additive element is called white copper, which is silver white and has metallic luster, so it is called white copper.

Bronze originally refers to copper tin alloy, and later copper alloys other than brass and white copper are called bronze.

Of course, the copper density is different for different copper.

Let’s first talk about the definition of copper density.

Definition of copper density: the ratio of copper mass to copper volume is called copper density.

Formula for copper density:

• Formula for copper density: ρ= m/V， ρ= dm/dV( ρM represents mass, V represents volume)
• Deformation of copper density formula: v = m/ρ， m= ρV，m=∫ρ(V)dV。
• The mass m can be measured by a balance, and the volume V of liquid and irregularly shaped solid can be measured by a measuring cylinder or a measuring cup.
• The density of a substance is constant, and it does not change with volume and mass. The density of different grades of copper does not change with the volume.

The density of different copper is different, but it can be roughly divided into the following types:

• The density of pure copper, and oxygen-free copper is 8.9 (g/cm³), and the density of phosphorus-deoxidized copper is 8.89 (g/cm³).
• The density of processed brass is 8.5-8.8 (g/cm³) and the density of cast brass is 7.7-8.55 (g/cm³).
• The density of processed bronze is 7.5-8.9 (g/cm³) and the density of cast bronze is 7.45-9.54 (g/cm³).
• The density of white copper is 8.4-8.9 (g/cm³).

How to calculate the density of steel?

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 measured by Archimedes’ law.

First, tie the iron block with a thin rope and weigh the gravity G of the metal block with a spring scale.

Then completely immerse the metal block in the water and weigh the apparent weight G’ of the metal block in the water with a spring scale.

Finally, by calculating the weight of iron via the formula ρ=Gρ_water/(G-G’) and you will get the result that the density of steel is 7.8 g/cm³ or 0.28 lb/in³.
