I'm an expert in material science with a keen interest in the properties and applications of various metals. When it comes to the question of whether tin is rust proof, it's important to clarify a few concepts.
Firstly, the term "rust" is often used colloquially to refer to the corrosion of metals, but technically, rust is the specific form of corrosion that occurs in iron and its alloys, resulting in iron oxide. This is a reddish-brown compound that forms when iron reacts with oxygen and moisture, leading to a flaky, porous, and brittle material that can weaken the metal structure.
Now, let's talk about tin. Tin is a relatively stable metal that does not rust in the traditional sense. It does not form iron oxide; instead, it can form a thin, silvery oxide layer when exposed to air. This oxide layer is not as detrimental to the structural integrity of the metal as rust is to iron. Tin's resistance to corrosion is one of the reasons it has been used historically for food storage and as a protective coating for other metals.
However, it's worth noting that tin can still corrode under certain conditions. For example, in the presence of certain chemicals or in a marine environment, tin can suffer from a form of corrosion known as "tin pest," which is a crystallographic transformation that can lead to a powdery form of tin. This is a rare phenomenon and occurs under very specific conditions, typically at very low temperatures.
Regarding the cost and application of tin, it's true that tin can be more expensive compared to other metals like steel. This is due to its scarcity and the processes involved in its extraction and refining. Despite its higher cost, tin is valued for its corrosion resistance, low toxicity, and the fact that it does not impart taste to food or beverages.
Galvanized steel, as mentioned, is a form of steel that has been coated with a thin layer of zinc. This zinc coating serves as a sacrificial layer, protecting the underlying steel from corrosion. When exposed to corrosive elements, the zinc reacts preferentially, corroding in place of the steel. This process is known as cathodic protection and is highly effective in extending the life of steel structures.
In summary, tin is not rust proof in the strictest sense, as it can still undergo a form of corrosion. However, it does not form iron oxide like iron does. Its resistance to corrosion, along with other desirable properties, makes it a valuable material for various applications, despite its higher cost compared to other metals.

Tin is too expensive. Also, tin does not 'rust', although it oxidizes. Your rust is iron oxide. Galvanized steel is steel with a thin zinc coating, likely hot-dip galvanization.May 4, 2015
