Aluminium Corrosion Resistance in Soils

The use of unprotected aluminium is limited, mainly to North America where between 1948 and 1963, 626 km of pipeline made of aluminium alloys (of which 462 km were 

Aluminium is used unprotected for underground passages (under motorways or railways) as corrugated sheet covered with backfill. In spite of a few limited experiences, some successful, aluminium should not be buried without protection, especially cables for the transportation of electrical energy and telecommunications, pipes for water adduction, heat exchange circuits for heat pumps, etc.
