Corrosion of aluminum and aluminum alloys pdf. Some of the present aluminium corrosion challenges are the ramifications from the elimination of chromates as inhibitors in protection schemes the tolerance of higher impurity levels due to the increased use of recycled metal the integration of lithium into alloys while retaining corrosion resistance and the sensitisation of non-heat treatable aluminium-alloys. While in the 2xxx series it appears as a narrow band on either side of the grain boundary in the 5xxx series it is manifested as a continuous path along the grain boundary.

There are three options. Severe localized corrosion was found throughout an aeration tank of a modular wastewater treatment plant. Corrosion of Aluminum Alloys.

Aluminum alloys have a high strength-to-weight ratio. Aluminum alloys of Al-Mn. Specifically pitting crevice corrosion galvanic corrosion and intergranular corrosion IGC were observed on the 5000 and 6000 series aluminum alloys used in the tanks construction.

More generally 1xxx 3xxx 5xxx and 6xxx series alloys offer good corrosion resistance. 13 Corrosion rate The rate of corrosion of aluminium in water depends on several parameters coupled to water. Alloy 2024 Poor Corrosion Resistance.

It has good toughness at cryogenic temperatures but it does tend to suffer from stress corrosion above about 150F though not as badly as other 5000 series aluminum alloys that have more Magnesium. To prevent aluminum corrosion you should consider. It also depends on the alloy composition elaboration technique extrusion rolling.
