Is it normal for aluminium prices to move less dramatically than copper, and why?
Short answer: Generally yes. Aluminium is produced by many smelters across a wide range of countries, and global stock levels tend to run higher relative to consumption than copper's do. Copper mine supply is more geographically concentrated, which tends to make copper prices swing harder and faster than aluminium's.

Copper mining is concentrated in a relatively small number of countries, so a disruption at a handful of major mines can noticeably tighten global supply. Aluminium smelting happens across a broader spread of producing countries, largely because the biggest input cost is electricity rather than a scarce ore deposit.
Inventory buffers also matter
Reported aluminium stockpiles have historically tended to sit higher relative to consumption than copper’s, meaning short-term supply hiccups are less likely to translate immediately into sharp price spikes.
What this means for timing a sale
Chasing short-term price swings on aluminium scrap is generally less rewarding than it can be for copper — though smelter shutdowns, tariffs, or a real demand shift can still move it meaningfully, just less often and less sharply.
