What Is the Density of Tungsten?

 

Tungsten is known for its remarkable heaviness. Its tungsten material density is about 19.254 g/cm³, which is nearly twice that of lead and more than five times that of aluminum. This high tungsten metal density makes it ideal for applications requiring compact, heavy, and durable components, from aerospace parts to radiation shielding.

• Tip: When designing CNC machined parts with tungsten, always account for its high weight per unit volume—ignoring it can increase material costs and tool wear.

 

 

 

How to Calculate the Density of Tungsten?

To calculate the tungsten mass density, you divide the metal’s mass by its volume. The formula is simple:

    ​

For example, if you have a tungsten piece weighing 1925 grams with a volume of 100 cm³, its tungsten specific gravity is 19.254 g/cm³. This calculation is essential for designing CNC machined parts with precise weight and balance.

• Tip: Always measure volume carefully—small errors can lead to costly mistakes in CNC machining services.

 

 

 

Why Is Tungsten So Dense?

 

Tungsten’s extreme density comes from its atomic structure. Each tungsten atom is heavy, and the atoms are packed tightly in a body-centered cubic crystal lattice, leaving little empty space. This combination of high atomic mass and compact arrangement results in its extraordinary tungsten weight density and specific weight, making it much heavier than most metals.

• Tip: Remember that tungsten’s high tungsten metal density affects CNC machining—it requires strong tools and careful planning to avoid excessive wear.

 

 

 

Methods for Measuring Tungsten Density

 

Measuring tungsten specific density accurately is essential for applications where precision matters. Different methods allow you to determine tungsten weight density and tungsten mass density depending on your sample size and required accuracy. Proper measurement ensures your CNC machined parts meet performance standards and reduces the risk of costly errors.

• Tip: Choose a method that aligns with your project’s precision needs to avoid machining mistakes.

 

Ohmic Pulse Heating Method

This method uses a controlled electric pulse to heat a tungsten sample rapidly. The temperature rise is then measured and used to calculate tungsten metal density. It is highly precise and ideal for small, high-purity tungsten samples.

• Tip: Only specialized labs should use this method—improper handling can damage samples and equipment.

 

 

Precision Weighing and Volume Measurement

The most common method involves weighing the tungsten sample and measuring its volume using geometric calculations or displacement techniques. Using the formula Density = Mass ÷ Volume, you can determine the tungsten material density accurately.

• Tip: Ensure the sample has smooth surfaces and no voids; errors in volume measurement can lead to significant density miscalculations.

 

 

Archimedes' Hanging Drop Method

This technique measures the density of tungsten by suspending a sample in a liquid and recording the apparent weight change. This allows calculation of tungsten specific gravity without cutting the material. It’s especially useful for irregularly shaped samples.

• Tip: Use a liquid that does not react with tungsten to avoid corrosion and inaccurate readings.

 

 

Machining of Tungsten Surfaces

Tungsten’s high density makes CNC machining challenging. Accurate density measurement before machining ensures correct tool selection and reduces wear. Understanding the tungsten weight per unit volume helps you predict cutting forces and plan for efficient material removal.

• Tip: Always communicate measured tungsten metal density to your CNC machining team to optimize process parameters and avoid tool damage.
