Metal Corrosion - Industrial Metallurgists
One common example is dezincifiion of brass alloys used for pluing, where the zinc is leached out of the alloy. The specific type of corrosion that occurs depends on the several factors including metal composition, metal microstructure, environment, component geometry, stress on the component, contact between metals, and the manner in which components are joined together.
Corrosion of Nonferrous Metals and Their Alloys | Hindawi
Corrosion comprises the reaction between a metal (or alloy) and its surrounding (environment). The corrosion process depends on the properties of both metal (and alloy) and surrounding (environment). Usually, the more important factors affecting corrosion are concentration, acidity (pH), fluid flow (velocity), temperature, and potential (oxidizing power).

Why does aluminium not corrode, but iron does? | …
10/5/2007· Aluminium does corrode, resulting in the formation of an aluminium oxide layer on its surface. The aluminium oxide layer is impermeable to moisture and air, so no further reaction occurs. Iron oxides and hydroxides however, are permeable to air and moisture, so corrosion can keep going through the metal, until all is oxidised.
