corrosion-resistant composite aluminum materials.

摘要

A corrosion resistant aluminum alloy based on commercial purity aluminum with deliberate additions of silicon and manganese and with a restricted iron content. The silicon and manganese ranges are controlled to provide an aluminum-silicon solid solution and to restrict or eliminate cathodic particles which have been found to cause pits. The alloy is highly resistant to corrosion, especially in environments where the alloy comes into contact with impure water.
