Is aluminum conduit corrosion resistant?

Aluminum Conduit aluminum rigid conduit combines light weight and corrosion resistance to provide a full-line of easy to install, low maintenance conduit whenever specifications call for aluminum.

Rigid Aluminum Conduit

Aluminum conduit, similar to galvanized steel conduit, is a rigid tube, generally used in commercial and industrial applications where a higher resistance to corrosion is needed. Such locations would include food processing plants, where large amounts of water and cleaning chemicals would make galvanized conduit unsuitable. Aluminum cannot be directly embedded in concrete, since the metal reacts with the alkalis in cement. The conduit may be coated to prevent corrosion by incidental contact with concrete. Aluminum conduit is generally lower cost than steel in addition to having a lower labor cost to install, since a length of aluminum conduit will have about one-third the weight of an equally-sized rigid steel conduit.

Advantages of aluminum conduit

The study found that rigid aluminum conduit saved engineers and contractors 17 percent in usage costs. Black iron and galvanized steel pipe are two common types of pipe used for compressed air systems. Colorable: Aluminum can be easily colored by anodization, and holds paint extremely well. This protective coating is clear, colorless, and non-staining.

Reduced installation cost, enhanced performance, improved safety, superior durability and highest strength to weight ratio of any metal are just some of the advantages.

The main advantage of running wires in a conduit is that running large amounts of wire can be more efficient, not to mention after a certain size it’s the only option. Aluminum can be finished in various ways.
