Why is aluminium alloy stronger than pure aluminium?

Answer 1

Well I'm not a metallurgist,but here goes eg; Zinc is a soft natural metal as is copper,but when they are mixed we have brass, whicch is harder but more brittle,or you can have iron ore, on its own will break verry easily but if you add 2 percent mg it becomes workable and stronger.

Another method of making a piece of metal stronger eg;samuari sword,where you have temperd steel with a harder alloy for cutting edge and would take 3 months to make,i think

an alloy is stronger than pure metal because in a pure metal all the atoms are the same size and ordered. but when another element is added it shifts the atoms making the layers harder to shift, therefore making it stronger.

Answer 2

The atoms in a pure metal are arranged uniformly in layers. When the metal is pure, the layers can move over each other freely. When other metals or non-metallic elements are present, however, the layers are less free to move because the other elements restrict their movement because they lie between the layers.

Answer 3

Alloying alters the physical and chemical properties of the original substance. Sometimes, the alloy can be better than the original substance and sometimes it will turn out worse. It all depends on the purpose for which you are using the alloyed metal. Alloys can exhibit the properties of both their parent elements or exhibit none at all! But often, alloys are better than pure metals because they have combined the desired properties of the two metals that they were made with.

For example, steel is an alloy of iron and carbon. Steel is much stronger than either of these metals and also has a higher rust resistance compared to iron. When reacting with each other, the smaller atoms of carbon slot in between the layers of iron atoms, therefore preventing them from sliding. This increases the rigidity, hardness and ductility of the metal.

Answer 4

An alloy is a combination of metals, usually created to enhance certain properties like strength or ductility. The advantage of alloys over pure metals is the ability to combine the best properties of multiple metals.

For example, alloyed steel is more hardenable than pure steel because the alloys enable the steel to maintain its hardenability at a lower cooling rate. This is very useful in manufacturing applications.

Answer 5

an alloy is stronger than pure metal because in a pure metal all the atoms are the same size and ordered. but when another element is added it shifts the atoms making the layers harder to shift, therefore making it stronger.

Answer 6

Alloying elements can modify the properties of a metal.
