Titanium Density: What is the Density of Titanium Metal?

what is the density of titanium

Titanium is renowned for its unique blend of strength, light weight, and corrosion resistance, making it a top choice for a variety of high-performance applications. But what exactly is its density?

In simple terms, density measures how much mass a substance has in a given volume. For titanium metal, this is an important factor because it directly influences its application in fields such as aerospace, medical devices, and high-end automotive parts.

What is the Density of Titanium?

Density is a fundamental physical property of materials, defined as mass per unit volume. For titanium, the density is approximately 4.506 grams per cubic centimeter (g/cm³). This value positions titanium between the densities of lighter metals like aluminum (2.70 g/cm³) and heavier metals such as steel (7.85 g/cm³) and nickel (8.90 g/cm³).

Density of Titanium lb/in³

The density of titanium is approximately 0.162 pounds per cubic inch (lb/in³).

Density of Titanium kg/m³

The density of titanium is approximately 4,506 kilograms per cubic meter (kg/m³).

Density of Different Types of Titanium Alloys

The density of different titanium alloys will vary, mainly depending on the elements added to the alloy and their composition ratios. Here are some common density ranges for titanium alloys:

Titanium AlloyDensity (kg/m³)Density (lb/in³)Density (g/cm³)
Pure Titanium (Grade 1)4,5060.1624.506
Ti-6Al-4V (Grade 5)4,4300.1604.43
Ti-6Al-4V ELI (Grade 23)4,4300.1604.43
Ti-3Al-2.5V4,4700.1624.47
Ti-5Al-2.5Sn4,4700.1624.47
Ti-4Al-4Mn-2Sn4,4800.1624.48
Ti-6Al-2Sn-4Zr-2Mo4,4300.1604.43

It’s important to note that while pure titanium has a density of approximately 4.506 g/cm³, titanium alloys can exhibit slight variations in density depending on their composition. These variations are due to the different elements alloyed with titanium, which can slightly alter its density while enhancing specific properties like strength and hardness.

Comparison with Other Metals

Titanium’s density is a critical factor in its selection for specific applications. To understand its significance, let’s compare it with other commonly used metals:

MetalDensity (kg/m³)Density (g/cm³)Density (lb/in³)
Titanium (Ti)4,5064.510.162
Aluminum (Al)2,7002.700.097
Steel (Carbon Steel)7,8507.850.284
Lead (Pb)11,34311.340.410
Copper (Cu)8,9608.960.325
Nickel (Ni)8,9088.910.323

Key Points

  1. Titanium vs. Aluminum: Titanium is significantly denser than aluminum, which has a density of about 2.70 g/cm³ (More information about aluminum density). However, titanium is much stronger, which is why it’s often chosen for applications requiring high strength-to-weight ratios.
  2. Titanium vs. Steel: Steel is much denser than titanium, with a density of approximately 7.85 g/cm³. This means titanium is about half the density of steel, contributing to its use in weight-sensitive applications such as aerospace components.
  3. Titanium vs. Lead: Lead is substantially denser than titanium, with a density of around 11.34 g/cm³ (More information about lead density). The high density of lead makes it useful for applications requiring radiation shielding, whereas titanium’s lower density makes it preferable for applications needing strength with less weight.
  4. Titanium vs. Copper and Nickel: Titanium is less dense than copper and nickel. Copper’s density is 8.96 g/cm³, and nickel’s density is 8.91 g/cm³. Despite this, titanium is often chosen over these metals for its superior corrosion resistance and strength-to-weight ratio.
