Compatibility Rating
At 20°C
Fair
Limited resistance - short-term exposure only
At 50°C
Poor
Not recommended - significant degradation expected
Why is Aluminium rated this way to Sodium Chloride?
Aluminium has limited resistance to Sodium 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.
