Aluminium properties
Which type of aluminium suits you the best?
Aluminium is remarkable for its low density and its ability to resist corrosion through the phenomenon of passivation. Aluminium reacts strongly with hydrochloric acid and caustic soda. The reaction with sulfuric acid is weaker, while it remains passive in contact with cold nitric acid.
