Alloys are commonly used in manufacturing. Which of the following is not a reason to use an alloy instead a pure metal?
Cast iron is more brittle than pure iron.
Are Metallic solids called alloys are made of one extremely pure element?
Yes... Alloys are combinations of metals and another compound. Some alloys can be made from the mixing of two metals such as copper (Cu) and iron (Fe). Other alloys are made by mixing a metal with a non-metal element. An example of that type of alloy is the extremely strong carbon-steel used in many products. Alloys are defined as homogeneous mixtures.
How are alloys used in coin making?
Alloys are frequently used to give a coin a particular color, or because a pure element may not have the right properties for coinage. In the US, layers of alloys and / or pure metals are used in what are called "sandwich" coins. These layers are chosen so that the outside of the coin has a particular appearance (silver-colored or gold-colored) but the entire coin has electromagnetic properties that can easily be distinguished in vending machines, transit fareboxes, and so on.
Which element is used in aerospace industries in alloys with other metals?
titanium
Why is PURE iron no good for use in building?
pure metals are too soft due to the neat arrangement of their atoms. hence alloys are usually used as the inconsistent atom sizes would prevent atoms from sliding pass one another:D
Why are airplanes made from aluminium alloys rather than pure alloys?
Alloys basically mean "a mix". A "pure alloy" would mean a pure mix. That doesn't really work. Alloys are generally used instead of pure metals b/c the characteristics of the Alloys are better than those of the pure metals. Aluminium Alloys are generally considerably stronger than pure aluminium while still being pretty much the same weight.
Why are alloys often used instead of pure metals?
Alloys are sometimes more useful than pure metals because alloys tend to be stronger though not necessarily. Pure metals tend to be softer than alloys, which are a mix of two or more metals, and therefore get dented, scratched, or broken more easily. Gold used in jewelry is a good example. Metal alloys have different structural and behavioral characteristics than pure metals. Alloying a metal also gives it a different appearance. In some cases alloys may result in a lighter metal without sacrificing other necessary characteristics. They may also be more cost effective.

Why alloys of aluminium are used to make aircraft bodies instead of pure aluminium?
Alloy aluminum is lighter in weight.
Alloys are used in electrical heating devices rather than pure metals. Give reason.?
Alloys are used rather than pure metals in electrical heating devices since they have low electrical conductivity and also a low melting point. Usually the alloys don't have a single melting point; they have a range of melting points. The temperature at which melting begins is called the SOLIDUS and the temperature at which melting is complete is called the LIQUIDUS.Student

Cast iron is more brittle than pure iron.
Why do you use alloys instead of normal metals?
There are different properties in alloys eg brass is stronger than bronze, steel is stronger than iron, more rust proof, they have different color, eg rose gold, different melting temperatures etc
What metals are used to make engine cylinder?

Why are many coins not pure metal?
Pure metal is often malleable (easy to bend) and reactive. Alloys (mixtures of metals) are used to help coins keep their shape (prevent forgery), for safety and cost purposes.
Element used to make alloys?
Alloys are mixtures of metals, such as sterling silver, which is an alloy of silver and copper.
Whether the resistivity of copper or its alloy is greater?
Copper alloy is often used in preference to pure copper due to its hardenss. Pure metals are usually soft and can be cut easily. They are not suitable for making any hard bodies. Therefore, alloys are used.
