Why do we use alloys?
Almost all metals are used as alloys—that is, mixtures of several elements—because they have properties that are superior to those of pure metals.There are many reasons for alloying, usually for Increase strength, increase corrosion resistance or reduce cost.
Is aluminum better than brass?
steel, Aluminium and Brass sheet metal are stronger and offer a high level of corrosion protection. However, steel is the strongest, while aluminum is the lightest. Brass, on the other hand, is the most conductive of the three metals.
2 What are the types of alloys?
There are two main types of alloys.these are called Alternative and Interstitial AlloysIn a replacement alloy, the atoms of the original metal are actually replaced with atoms of roughly the same size as another material. For example, brass is an example of a substitute alloy for copper and zinc.

Is aluminum stronger than copper?
Copper is stronger than aluminum. It has less expansion but a similar maintenance schedule for both materials. Copper has almost twice the current capacity of aluminum, which makes them slightly smaller in size than aluminum wound transformers.
Why doesn’t the aluminum foil react?
Aluminum is a reactive metal that easily forms an oxygen layer on top of it when it comes in contact with air.So, if you put the foil on the outside, it gets that immediate oxide layerand becomes unresponsive.
