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 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
The term "base metal" or "parent metal" in an alloy refers to the primary metal that forms the majority of the alloy's composition. It serves as the foundation of the alloy, with other elements added to enhance its properties. The base metal determines the alloy's primary characteristics and properties.
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.
An alloy is a mixture of different metals or of a metal with a non-metal. Steel is a combination of iron and carbon.
When a mixture of two or more elements includes at least one metal, it is called an alloy. Alloys are formed by combining a metal with one or more other elements, with the properties of the alloy often differing from those of its individual components.
An alloy is a mixture of elements that has the properties of a metal. Alloys are typically made by combining a metal with one or more other elements to enhance specific characteristics such as strength, hardness, or resistance to corrosion. Examples of alloys include steel, bronze, and brass.
probably an alloy or alloid
An alloy is a solution of a metal dissolved in another metal. This forms a homogeneous mixture with properties different from those of the individual metals.
