What is the element used in aircraft?

Aluminum-magnesium alloys are used in making parts in aircraft. Aluminum-magnesium alloys are lighter than other aluminum alloys and much less flammable than alloys that contain a very high percentage of magnesium.Aluminum alloys are alloys in which aluminum (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon and zinc.Aluminum alloys are widely used in engineering structures and components where light weight or corrosion resistance is required.Alloys composed mostly of aluminum have been very important in aerospace manufacturing since the introduction of metal skinned aircraft.


Which impurities are added to pure gold for making jewelry?

Copper and silver are commonly added to pure gold to create alloys that are suitable for making jewelry. These impurities help enhance the durability and strength of the gold, as pure gold is too soft to be used on its own for most jewelry designs.


What is the raw materials of Aluminum?

Aluminium is extracted from an ore called bauxite. In can be used as a raw material though, such as when alloys are made with aluminum additions. Aluminium is not found natuarally as aluminum.


Explain why metals alloys are often used in place of metals?

There are a few different reasons. 1. Some alloys are stronger than natural metals. 2. Weight, if you need a light weight material, alloys have more to offer, eg. aluminum. 3. Cost 4. Flexibility These are just a few of the many answers.


Why is aluminium usually mixed with other metals before it is used?

There are many different answers but some of the most common ones are:Aluminium is very expensive when being extractedAluminium on it's own is a soft metal, but it makes hard alloys. these can be used for planes, electricity cables, window frames, etc.
