Because carbon steels are not very highly alloyed, it is not surprising that most grades do not exhibit large differences in atmospheric-corrosion rate. Nevertheless, alloying can make changes in the atmospheric-corrosion rate of carbon steel.
The most favourable case is a very large anodic surface area and a small cathodic surface area. The galvanic corrosion is a local corrosion, and is therefore limited to the contact zone. It is unusual to see galvanic corrosion on aluminum in contact with stainless steel (passive).In contrast contact between copper, bronze, brass and different kinds of steel alloys (passive and active) and aluminum can cause severe corrosion so it is advisable to provide insulation between the two metals.he galvanic series for metals shows that aluminum will be the anode of the galvanic cell in contact with almost all other metals and hence the one which suffer from galvanic corrosion. The galvanic corrosion performance of the different aluminum alloys is quite similar, so that changing alloys cannot solve the problem.
