Why is Aluminium rated this way to Cobalt Chloride?
Aluminium has limited resistance to Cobalt Chloride. Short-term exposure may be acceptable, but prolonged contact is not recommended.
⚠️ When NOT to use Aluminium
Avoid using Aluminium with strong acids (HCl, H₂SO₄), strong alkalis (NaOH), and mercury compounds which destroy the protective oxide layer.
