Why is Aluminium resistant to Acrylonitrile?
Aluminium shows excellent resistance to Acrylonitrile due to its protective oxide layer (Al₂O₃) that forms naturally and resists many chemicals.
⚠️ 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.
