the particles in pure iron, and any metal, are in layers which can slide over each other easily and therefore make the metal quite weak. howerver when other partcles of different sizes make the layers more uneven, the metal becomes stronger.
hope this helped, you can copy word for word i dont care :)

∙ 13y agoFirst off, iron is not particularly pure and is fairly brittle. It contains a lot of carbon, sulfur, and silica. Removing the impurities, particularly carbon, makes steel. Adding other metals can make the steel harder making it an alloy. Some additions are nickel, chromium, vanadium, and molybdenum. They change the physical structure of the molecules resulting in a harder metal. Heat treating and cold forming can also make metals harder.

∙ 9y agothe atoms are closer together, making it denser and therefore stronger (think of the differences between a solid and liquid, but to a lesser degree)
Actually "steels" are just just forms of elemental iron that have impurities, such as carbon, introduced into the material during manufacturing. when Iron is heated the space between the crystal lattices is farther apart. (actually completely different lattice structures all together) When the iron hardens these impurities are trapped within the crystal lattice in what are know as interstitial sites. Because of iron's lattice structure (FCC), slip (when metal bends) occurs along the close packed planes of the crystal lattice. Carbon impurities in the interstitial sites reduce the amount of slip between plains making the material stronger.

∙ 13y agoThe true answer is quite in depth. The addition of carbon to iron makes steel. Adding other alloying elements produces a range of steels including all the stainless varieties. Addition of carbon interferes with the movement of dislocations which makes the original iron harder. However it is easier to explain by saying allying elements fillin the interstices in the iron matrix.

∙ 11y agoThat's like asking why two elephants are stronger than one. Let me make it REAL simple, when you alloy iron with another metal, it has the combined strength of both, iron and the other metal.

What is an advantage of using alloy instead of pure iron?
Iron as an alloy is stronger and has a higher melting point. It can also be made to be much more resistant to rust (the most resistant alloy being stainless steel). Hence it is preferred to pure iron.Pure iron is quite brittle and very susceptible to rust. Iron alloys maintain the strength of iron and make it more malleable (less brittle) and can also make the alloy resistent to rust.
What are the benefits of stainless steel compared to pure iron?
Pure iron is soft, so knives will not stay sharp for long and the tynes of fork will easily bend. Pure iron would get rust on it. stainless steel is rust proof. stainless steel is harder than pure iron. You can also go to this website for better answer: but links are not allowed to given (so so sorry) :( :)
Why would iron be used on a magnet rather than steel?
because pure iron have not carbon, that disrupt the magnetic field.
Why a bar of the brass is harder than a bar of copper?
Because brass is an alloy of copper & zinc - the zinc atoms change the geometry of the copper crystals - making it less flexible.
Why is iron heavier than copper?
Copper is more dense than iron, if that is what is being asked. The density of copper is about 8.94 grams per cubic centimeter. Iron had a density of about 7.874 grams per cubic centimeter.
What are two advantages. of using alloys instead. of pure metals?
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 ironAn alloy of copper and tin makes bronze which is harder and more corrosion resistant than either of the pure metals
What are two disadvantages of using alloys instead of pure metals?
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 ironAn alloy of copper and tin makes bronze which is harder and more corrosion resistant than either of the pure metals
How hard is gold?
Gold can be both soft and hard depending on how pure it is, pure gold (24K) is softer than a gold alloy. And the lower the number the harder it is. 10K is harder than 14K, 14K is harder than 18K, and 18K is harder than 24K (pure gold).

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.
Is steel harder than platinum?
Yes, most steel is harder than pure platinum. Steel is an alloy of several different elements. If you were to add alloying elements to Platinum, it would become harder as well.
Difference between copper and bronze?
Iron is more brittle than bronze and is harder, but iron rusts and bronze doesn't.Iron is a pure substance and is oxidised relatively easily. Iron has to be coated with paint, oil, plastic, chrome, zinc to stop it from reacting with the oxygen in the air.Bronze, however, is a mixture of copper and tin. Bronze tools were used by many civilizations but iron tended to be stronger. Especially the alloy of iron that is mixed with carbon to form steel. Civilizations that had iron weapons tended to be able to conquer those that did not. A good example is the way Europeans conquered South America or indigenous populations in many countries.AnswerBronze is a mixture of Copper and Tin and harder than pure Iron which is a single metal. The addition of other metals such as 1 to 2% phosphorus makes bronze even harder. This is why Phosphor-Bronze is used for bearings. Some modern Bronzes have used other metals in the alloy such as aluminum, manganese, and zinc The main advantage of iron, and why humans used it more, is simply that it is cheaper and more abundant.
Is gold a soft or hard metal?
gold can be both soft and hard depending on how pure it is, pure gold (24K) is softer than a gold alloy. And the lower the number the harder it is. 10K is harder than 14K, 14K is harder than 18K, and 18K is harder than 24K (pure gold).
Would a steel or iron chain be tougher to break?
Steel, which has a higher tensile strenght than pure iron, would be toughest to break. Steel is an iron alloy.
Why is it that steel is made up with alloy?
the various alloys have properties that are better for certain applications than pure iron. Carbide Steel is stronger than Iron Stainless Steel doesn't rust as quickly as Iron.
Why Is Brass Harder Than Copper?
Brass is harder because it is an alloy of copper with tin.
Is iron harder than steel?
Yes, Absolutely......... Gold is softer than Iron... Gold becomes Harder because of other components that is being added like Silver and Copper. They add these components to add strength into the Jeweleries.
