Why does a pure metal have superior conductivity compared to an alloy?

∙ 12y ago
Copper is a pure metal while kanthal is an alloy. An alloy is a material consists of mixture of two or more elements that are metals and nonmetals. Therefore, kanthal alloy is a metal with addition of some alloy elements such as iron, chromium and aluminum. The addition of alloy elements to pure metals caused additional scattering of the conducting electrons and thus increase the electrical resistivity of pure metals. As the temperature increases, the resistivity of copper increases while the resistivity of kanthal alloy decreases.

Is gold a metal or a alloy?
metal
What is an alloy that is not metal plated?
Bronze is an alloy that is not metal plated. It is composed of copper and tin.
What is uranium electrical conductivity?
Uranium is a metal and as such, it has excellent electrical conductivity.
What can an alloy do?
Alloying one metal with other metal(s) or non metal(s) often enhances its properties.Alloying is changing chemical composition of steel by adding elements with purpose to improve its properties as compared to the plane carbon steel.Alloys are used in some applications, where their properties are superior to those of the pure component elements for a given application. Examples of alloys are steel, solder, brass, pewter, phosphor bronze and an amalgam.
Why does a metal have good conductivity?
yes
Is alloy a metal or a compound?
An alloy is neither an elemental metal nor a compound; instead it is a mixture including at least two elemental metals. Most alloys have the general metallic properties of high conductivity for electricity and heat and malleability.
Is a nickel a insulator?
Nickel is a metal and therefore a conductor. It does not have particularly good conductivity like copper or silver. In alloy form it is used in wirewound resistors.
What does conduction of different metals mean?
it means the rate transfer of heat through this metal and coductivity is the measure of this abillity
Why gold are being used in electrical wires?
For its superb conductivityAnswerGold is not used to make fuse wire. Fuse wire is usually made up of an alloy of various combinations of metal (e.g. tin and lead) which results in the wire having good conductivity and a low melting point. In fact, gold does NOT have 'superb conductivity'; it is a relatively-poor conductor when compared with silver, copper, and aluminium.
WHAT IS THE elements is a metal?
That metal, if it is a pure elemental metal. Each element that makes up the alloy, if it is a metal alloy.
What two properties of metal make them useful materials for the electrical wiring at home?
Mainly, metals are extremely good conductors of electricity, compared to most other materials.
What is a mixture of elements that has the properties of a metal?
alloy
Is iron a metal alloy?
Iron is not an alloy - it's a metal element. An alloy is a mixture of two or more elements.
Does aluminum have conductivity?
Yes,Aluminum have conductivity because it is a metal
What is a metal plus a metal?
An alloy?
Is gold a metal or a alloy?
metal
What is an alloy that is not metal plated?
Bronze is an alloy that is not metal plated. It is composed of copper and tin.
