To determine which metal is NOT strong enough to take oxygen from aluminum oxide (Al₂O₃), we must assess the reactivity of each metal provided. The metals listed can be categorized based on their ability to displace oxygen from oxides.

1. **Copper**: This is a less reactive metal and does not have the ability to displace oxygen from aluminum oxide. It is placed lower in the reactivity series.

2. **Sodium**: Sodium is a highly reactive alkali metal and can easily displace oxygen from aluminum oxide.

3. **Potassium**: Similar to sodium, potassium is also very reactive and can displace oxygen from aluminum oxide.

4. **Calcium**: Calcium is a reactive metal and can also displace oxygen from oxides.

### Conclusion
Based on the reactivity of these metals, **Copper** is NOT strong enough to take the oxygen from aluminum oxide.
