![]() The zinc layer eventually wears off, causing the steel below to eventually rust. However, the protection is usually only temporary. The zinc coating protects the steel by preventing water and oxygen from reaching it. Galvanized steel: Galvanized steel consists of carbon steel with a thin layer of zinc on top of it.When aluminum is exposed to water it creates a film of aluminum oxide over the metal that protects the metal beneath it from corrosion. Aluminum, which is an alloy, contains very little iron, which is a key ingredient for producing rust. Aluminum: Aluminum is a popular material of choice for automobiles not only because it’s lightweight but also because it resists corrosion.While the iron in the alloy is susceptible to rust, the chromium creates a protective layer around the metal surface that resists corrosion while preventing oxygen and water from reaching the iron underneath it. Stainless steel: Stainless steel is an alloy of elements that include mainly iron and at least 18 percent chromium.One way of preventing your grills, siding, fencing, and gates from rusting is to select products that use metals that are corrosion-proof. For example, iron easily loses electrons to oxygen when both come into contact with water, creating rust. Corrosive MetalsĬorrosive metals are those that easily lose electrons combined with an element that absorbs them. While rust is destructive, weakening and ultimately destroying the metal, the green patina that forms on copper serves as a shield that protects the metal underneath it from the elements. Though the reactions are similar, the effects on the metal are quite different. In fact, it’s the copper content that’s in sterling silver that causes it to tarnish and in brass that causes it to turn green. Like iron, copper also reacts to water and air, causing a chemical reaction that forms a green patina on the outside of the metal. Rust occurs when iron reacts with oxygen in the air and water to create a compound called iron oxide. Technically copper can corrode, but that process does not harm the metal. Without a doubt, it’s been a brilliant addition to my maintenance routine!Ĭheck out STA-BIL® online for other awesome products for all of your engine and equipment needs.Since iron is a key ingredient for rust, only metals that contain iron such as cast iron and steel are corrosive.
