Available Aluminum Alloys


Deep 7 Logo - The Deep7 aluminum alloy was designed as an effective, offshore alloy, for use in cold, deep water environments. The low Iron (Fe) content of the alloy ensures that it activates in lower temperatures and protects the platform or pipeline it is connected to for the designed life of the cathodic protection system.

Deep 10 Logo- The Deep10 aluminum alloy was designed as an effective, general purpose offshore alloy, for use in tropical water environments. In cold, deep water, the Deep7 alloy is more effective, as it has a lower Iron (Fe) content.
