Is aluminum corrosion resistant
Web1 nov. 2024 · Aluminum has good corrosion resistance and forms a passive oxide layer on its surface which is what enables it to resist corrosion. Most grades of aluminum are very chemically resilient but grades 1xxx, 3xxx, and 5xxx are the most corrosion-resistant metals in the aluminum family. They are particularly tough in a pH range of 4.5 to 8.5. WebThis is called Passivation. (Stainless steel can't passivate in chlorinated water). Red brass and bronze typically resist pool corrosion well. And aluminum does well in pool areas, but not in the water itself. In saltwater pools, nickel aluminum bronze is recommended. Another approach is to coat the metal in a sealant, which keeps water out.
