Corrosion of Alloys

This division between metals and alloys is somewhat artificial. A metal alloy is a mixture of two or more metals. Alloys are usually less malleable and ductile than pure metals and tend to have lower melting points. They do, however, have other properties which make them more useful than pure metals. An alloy is made by melting the different metals in the alloy together. The amounts of each metal are usually quite important.

A modern and comprehensive document on the subject is the second edition of the classic CORROSION BASICS textbook. Some excerpts of that document have been used to assemble the pages listed here:

Aluminum alloys

Brass

Bronze

Lead alloys

Magnesium alloys

Nickel alloys

Stainless steel

Steel

Weathering steel
