Detailed Product Description

Aluminum tube series

The chemical characteristics of aluminum: The anti-atmospheric corrosion performance is good, because it is easy to form dense surface of the alumina membrane, it can prevent further internal metal oxide, aluminum and concentrated nitric acid, organic acid and basic food adverse reactions
