its' in the book!
da :)
An alloy is less reactive and much stronger, instead of using a pure metal it may be reactive and weaker.
An alloy is a mixture of different metals or of a metal with a non-metal. Steel is a combination of iron and carbon.
alloy
An alloy is used where a pure metal is not sufficient. As an example, the superstructure of an aircraft is aluminum. By itself it is too soft and does not have the correct properties. So Aluminum is usually alloyed with a small amount ( 2- 3% ) of copper. This makes an aerospace alloy that is extremely useful.
i need to answer this --> Properties of alloy that are different to and more useful than the main metal... i think this means what do they do?
An alloy is a mixture of elements that has metallic properties. The properties vary depending on the percentage mix.
metal shiny and hard
A metal alloy behaves differently than a pure metal because the different chemical properties of the metals in an alloy both contribute to the alloy's properties. Certain alloys may be stronger than the original metals because one metal may fill a "gap" in the other's structure. Of course, other properties besides strength are also changed in an alloy.
probably an alloy or alloid
I do believe that's an alloy.
Alloying of a metal is when you mix one metal with another thus forming an alloy.
