Alloys can add corrosion resistance to a metal
they can be depending on the alloy composition
yes aluminiu is resistant to corrosion
why not
Rusting, hardenability and strength all comparative to alloy
Alloys are useful (if this is what the question is getting at) because mixing elements of the periodic table alters their colligative properties.i.e. mixing two metals could change substance's melting point, allowing it to more easily resist high temperatures. Also, mixing metals can change the way they bind together, and create an altogether stronger material than you can find using any single metal alone.They can improve a metal's properties
Alloys are sometimes more useful than pure metals because alloys are stronger - or tougher (toughness is resistance to fracture). Pure metals tend to be softer than alloys and therefore tend to get dented, scratched, or broken/fractured more easily. Alloys are often lower cost than pure metals but not necessarily so. As an example, stainless steel is more expensive than pure iron.
Corrosion is a chemical reaction that weakens a metal. It is a redox reaction, to be exact. By creating an alloy, new atoms (or different rations of atoms) are added in the metal being made, which changes the structure of the metal. This can form stronger bonds, which can be resistant to the redox corrosion reaction.Note: Alloys can be made that have a worse resistance to such reactions, but there is no market for them, so they are not sold.
Foam resistance is a term that is commonly used in companies that create injection molds and fire resistant equipment. This term means that a product is able to resist damage or corrosion when it is in direct contact with chemicals or solvents.
Pitting is the most common type of corrosion found on aluminum and magnesium alloys.
Metals are hard, resistant to abrasion, resitant to high temperatures, they have a good thermal conductivity, many alloys resist to corrosion etc.
Corrosion
Titanium and platinium resist corrosion well. So does hafnium, tantulum, tungsten and a whole flock of the transition metals. Yes, a whole flock. There are at least a dozen of the metals that stand up to corrosion well. We don't hear about them all that often because they're so "exotic" in their scarcity and in their oft unseen applications. These are elemental metals. Whole families of alloys resist corrosion. The stainless steels are arguably the most widely used. Brass and bronze are fairly corrosion resistant, as exemplified by their marine applications. Zircaloy is used in the manufacture of reactor fuel elements. That stuff is tough. Metals suppliers have whole catalogs full of obscure alloys that are extremely corrosion resistant.

Corrosion. :P
1. Gold alloys are resistant to moisture. 2. Gold alloys are good conductors of electricity.
them most common resistant is plastic!!
To make them pretty and to resist corrosion.
Destruction of metallic (especially from iron or iron alloys) structures.
Plating can be used for resist the rust & corrosion.
gold is commonly used for this purpose
