What Is the Density of Aluminum? Aluminum has a density of 2.70 grams per cubic centimeter. This remarkable property makes it indispensable across countless modern applications. From the aircraft soaring through skies to the beverage can resting in your hand, aluminum's density plays a silent yet vital role in shaping everyday life.
What Is the Density of Aluminum? Short Answer
Aluminum has a density of 2.70 grams per cubic centimeter.
1. Understanding Density
Density represents the relationship between an object's mass and its volume. The equation stands as:
Density = Mass / Volume
For aluminum, this translates to 2.70 grams occupying every cubic centimeter of space.
Practical Significance
- Weighs less than steel (7.85 g/cm³) → Revolutionized transportation design
- Maintains structural integrity → Perfect for high-stress environments
2. Aluminum Among Other Metals
| Metal | Density (g/cm³) |
|---|
| Aluminum | 2.70 |
| Steel | 7.85 |
| Copper | 8.96 |
| Titanium | 4.51 |

10 FAQs
- Does aluminum’s density change with temperature?
- Yes, but very slightly (negligible for most uses).
- What’s the lightest aluminum alloy?
- Al-Li (Lithium-aluminum, ~2.55 g/cm³).
- Why isn’t aluminum used in shipbuilding?
- It’s expensive vs. steel, but some military ships use it.
- How does recycled aluminum compare in density?
- Same as new (2.70 g/cm³).
- Can aluminum be lighter than air?
- No, even foamed aluminum is heavier than air.
- Does aluminum’s density affect conductivity?
- No, conductivity depends on electron mobility.
- Why is aluminum foil so thin but strong?
- Density allows thin sheets without breaking.
- Is aluminum powder less dense?
- No, but it takes up more volume due to air gaps.
- Which country produces the most aluminum?
- China (60% of global supply).
- Will future tech make aluminum obsolete?
- Unlikely—researchers keep improving alloys.
