Zangetsu might have elemental powers. During ichigo and zarakis' fight with his inner world Hollow ichigo weild zangetsu and it emitted heat. Zangetsu hates rain and whenever ichigo is sad or in despair i rains. Given that the true zangetsu is a dual blade it might have dual elemental powers and melee powers.
