What is an advantage that alloys might have over many pure metals?
Wiki User
∙ 10y ago
Alloys (mixtures of metals and other elements) have different properties form pure metals.
Two examples:
- An alloy of carbon & iron males steel which can be much harder than iron
- An alloy of copper and tin makes bronze which is harder and more corrosion resistant than either of the pure metals

∙ 14y agoAlloys can be defined as : a mixture of a metal as a main component, and another element which may be metal or non-metal.
By adding atoms of other elements into the crystal lattice of the metal, the properties change. This may include a change in:
-colour
-hardness
-malleability
-electrical conductivity
-melting point
An alloy is a mixture of metals that are also elements.

∙ 14y agoThere are two distinct advantages of using alloys in various objects instead of pure metals. They are:
1.) Alloys are significantly cheaper to produce and ship. This is because any "pure" metal is hard to gather in larger quantities and would be very expensive to produce.
2.) Alloys are lighter than pure metals, therefore easier to ship. Ex: Post-1982 pennies are made from an alloy of copper and zinc, it's like a sandwich. They are very easy to ship and less expensive to make.

Why are alloys harder than metals?
Alloys are not necessarily harder or stronger than pure metals. For example gallium and aluminum form an alloy that is extremely weak. Many of the alloys we know of are stronger than pure metals because those are the ones we find most useful. In most pure metals, there will be gaps in between atoms. In many alloys we fill in those gaps with some other type of atom, adding extra support.
Why do we use alloys 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.
What happens if ferrous metals are left outside?
There is only one ferrous metal-iron- but there are many ferrous alloys. Iron and the iron in most of the alloys will oxidize quickly-that is, rust.

Explain why metals alloys are often used in place of metals?
There are a few different reasons. 1. Some alloys are stronger than natural metals. 2. Weight, if you need a light weight material, alloys have more to offer, eg. aluminum. 3. Cost 4. Flexibility These are just a few of the many answers.
What is an advantage that alloys might have or many pure metals?
Some advantages are: increased hardness, resistance to corrosion, better workability, improved mechanical properties, improved or different aspect, etc.
What do metals weigh?
There are many various types of Metals and metal alloys. Magnesium is one of the lightest metals. Aluminum alloys is next. Steel alloys and Lead and Gold are the heaviest metals.
How many alloys are made?
Many alloys are made by melting metals and mixing them together in carefully measured amounts.
What plutonium mixes with?
Plutonium can form many alloys with other metals.

Could cobalt react to other metals?
Cobalt form many important alloys with other metals.
Why are many metals used as alloys?
alloys are probably cheaper to make and stonger then an element or a simple metal. Alloys are easier to make. It is difficult to find a simple metal.
What does mix with gold?
Gold can be mixed with Mercury - formation of an amalgam; also gold can form alloys with many other metals.
Can alloys be made on earth?
Alloys are a mixture of two or more metals. Man made alloys include brass and bronze. In nature alloys occur in almost any case there a metallic ore is found. Gold contains traces of lead, nickel ore contains many other metals and copper ore is specifically treated to remove more valuable metals present in the ore.
what metals can be concentrated by magnetic separation?
Iron and many iron alloys, nickel and cobalt.
How is alloys made?
Many alloys are made by melting metals and mixing them together in carefully measured amounts.
