Aluminum is a more chemically reactive metal than iron and thus should be less corrosion-resistant than steel. However, the actual answer to the above question on which metal is more corrosion resistant is: it depends on your formula chemistry. Steel typically corrodes very rapidly when the solution (formula) pH is below approximately five.
Oct 03, 2018 This is due to its light weight, but also to its resistance to corrosion. Aluminum alloys contain almost no iron and without iron, the metal can't actually rust, but it does oxidize. When the alloy is exposed to water, a film of aluminum oxide forms quickly on the surface.
While anodized aluminum and stainless steel offer stronger corrosion-resistance than most metals, they can still be exposed over time. And when put together, corrosion can still occur. If you have any questions about anodizing or how you should finish your metal part, our team is more than happy to help you through the process.
