Alumina vs Aluminum: Understanding the Difference for Enhanced Performance
Distinguishing between alumina and aluminum is crucial for industries seeking optimal material selection. While they share a close relationship, these substances possess distinct properties that impact their suitability for specific applications.
What is Alumina?
Alumina, also known as aluminum oxide (Al2O3), is a compound formed when aluminum is combined with oxygen. It is a versatile material with exceptional hardness, high melting point, and excellent thermal conductivity.
| Feature | Alumina |
|---|---|
| Chemical Formula | Al2O3 |
| Appearance | White, crystalline powder |
| Hardness | 9 on Mohs scale |
| Melting Point | 2,072°C (3,762°F) |
What is Aluminum?
Aluminum, on the other hand, is a lightweight metal with high strength and corrosion resistance. It is widely used in construction, automotive, and aerospace industries.
| Feature | Aluminum |
|---|---|
| Chemical Formula | Al |
| Appearance | Silvery-white metal |
| Hardness | 2.7 on Mohs scale |
| Melting Point | 660°C (1,220°F) |
Key Differences
The critical differences between alumina and aluminum can be summarized as follows:
