A common question about laser eye surgery is simply, âHow much is LASIK?â The best answer is this: There is no single answer. The cost of LASIK varies widely from the incredible $299 per eye on TV commercials to the equally incredible $5,000 per eye.
A alloy is a mixture or solid solution of two metals or a metal and a non metal. Mixtures of metals, any metals typically when one or more are molten.
An alloy is a mixture of two elements, one of which is a metal. Alloys often have properties that are different to the metals they contain. This makes them more useful than the pure metals alone. For example, alloys are often harder than the metal they contain. Alloys contain atoms of different sizes, which distorts the regular arrangements of atoms. This makes it more difficult for the layers to slide over each other, so alloys are harder than the pure metal.
