The density of pure aluminium is approximately 2,710 kg/m³.
Understanding Aluminium Density
Aluminium is well-known for its relatively low density compared to many other metals, which contributes significantly to its widespread use in various industries.
Pure Aluminium Density
Based on the provided reference, the density of pure aluminium is stated as being about 2,710 kg/m³. This figure represents the mass of pure aluminium contained within a cubic meter of volume.
Aluminium Alloy Density
When aluminium is mixed with other elements to form alloys, its density can vary slightly. The density of aluminium alloys typically ranges between 2,640 kg/m³ and 2,810 kg/m³. As you can see, this range does not vary widely from the density of pure aluminium, meaning that alloys generally retain the lightweight characteristic of the base metal.
Understanding aluminium's density is crucial in many applications:
- Aerospace: Its low density makes aircraft lighter, improving fuel efficiency.
- Automotive: Used in car bodies and components to reduce weight and improve performance.
- Construction: Allows for lighter structures and components compared to steel.
Here's a summary of the density figures:
| Material Type | Approximate Density (kg/m³) | Range (kg/m³) |
|---|---|---|
| Pure Aluminium | 2,710 | N/A |
| Aluminium Alloys | - | 2,640 to 2,810 |
These figures highlight why aluminium is considered a lightweight metal, especially when compared to materials like steel (which has a density of around 7,850 kg/m³).
