Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Alloy shopping experience:
1. Compare - without doubt the biggest advantage that the Alloy offers shoppers today is the ability to compare thousands of Alloy at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.
2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about
3. Testimonials - don't know anybody that has bought a Alloy? Wrong! If the Alloy is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.
4. Questions - Got a question about Alloy then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....
5. Reputation - Never heard of the company selling Alloy? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Alloy and build up a picture of their reputation for sales, returns, customer service, delivery etc.
6. Returns - still worried that even after all of the above your Alloy wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.
7. Feedback - happy with your Alloy then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.
8. Security - check for the yellow padlock on the Alloy site before you buy, and the s after http:/ /i.e. https:// = a secure site
9. Contact - got a question about Alloy, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.
10. Payment - ready to pay for your Alloy, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.
An
alloy is a homogeneous hybrid of two or more
chemical element, at least one of which is a
metal, and where the resulting material has
metallic properties. The resulting metallic substance usually has different properties (sometimes substantially different) from those of its components.
is a metal alloy whose major component is
iron, with carbon content between 0.02% and 1.7% by mass.
Intro
Alloys are usually prepared to improve on the properties of their components. For instance,
steel is stronger than iron, its primary component. The physical properties of an alloy, such as
density,
reactivity and
electrical conductivity and
thermal conductivity may not differ greatly from the alloy's elements, but engineering properties, such as tensile strength,Adelbert Philo Mills, (1922)

Kainer, (2003) Magnesium Alloys and Technology, Wiley Publishers, 293 pagesISBN 352730570X can be substantially different from those of the constituent materials. This is sometimes due to the differing sizes of the [atoms in the alloy, since larger atoms exert a compressive force on neighboring atoms, and smaller atoms exert a tensile force on their neighbors. This helps the alloy resist deformation, unlike a pure metal where the atoms move more freely. Alloys may exhibit marked difference in behaviour even in the case of small amounts of impurities being one element of the alloy; for example impurities in semiconducting
ferromagnetic alloys lead to different properties as first predicted by White, Hogan, Suhl and Nakamura. C. Michael Hogan, (1969)

Unlike pure metals, most alloys do not have a single [melting point. Instead, they have a melting range in which the material is a mixture of solid and
liquid phases. The temperature at which melting begins is called the
solidus (chemistry), and that at which melting is complete is called the
liquidus. However, for most pairs of elements, there is a particular ratio which has a single melting point; this is termed the eutectic mixture.
Classification
Alloys can be classified by the number of their constituents. An alloy with two components is called a
binary alloy; one with three is a
ternary alloy, and so forth. Alloys can be further classified as either
substitution alloys or
interstitial alloys, depending on their method of formation. In substitution alloys, the atoms of the components are approximately the same size and the various atoms are simply substituted for one another in the crystal structure. An example of a (binary) substitution alloy is brass, made up of copper and zinc. Interstitial alloys occur when the atoms of one component are substantially smaller than the other and the smaller atoms fit into the spaces (interstices) between the larger atoms.
Terminology
In practice, some alloys are used so predominantly with respect to their base metals that the name of the primary constituent is also used as the name of the alloy. For example, 14 Carat (purity)
gold is an alloy of gold with other elements. Similarly, the silver used in
jewelry and the
aluminium used as a structural building material are also alloys.
The term "alloy" is sometime used in everyday speech as a synonym for a particular alloy. For example, automobile wheels made of "aluminium alloy" are commonly referred to as simply "alloy wheels". The usage is obviously indefinite, since steels and most other metals in practical use are also alloys.
