Iron as a metal in the pure form is somewhat fragile. But iron mixed with some impurities like Carbon is very strong which is used in the construction of bridges. This iron mixed with impurities is called as Cast Iron.

What is soldering iron and how do you use it?
Soldering iron is used in heating the metal for soldering. If you want to learn more about soldering iron visit en.wikipedia.org/wiki/Soldering_iron.
Why should you return a soldering iron to its stand when not in use?
Because it stops the metal tip from oxidising.
What is ferrous metals?
a ferrous metal is a metal primarily made of iron and other metals to give the correct properties Iron is often referred to as a ferrous metal, but the word ferrous really refers to compounds containing iron. Compounds containing iron having a valance of +2 are ferrous; those compounds containing iron having a valence of +3 are ferric. In a more general sense, ferrous metals are metals or metal alloys that contain the element iron. Steel, for example, is a ferrous metal, and there are a number of other alloys that contain iron. Use the link below for more information. all ferrous metals are magnetic and contain a small amount of other metals to provide the correct properties
Why is iron a poor metal to use for water pipes?
Because it rusts very easily. You woudn't want to use rusty water, believe me.
Why can planning be use to obtain the element gold but cannot be use to obtain the element iron?
I think the word you seek is Panning, not Planning. Gold, when found as a fairly pure metal, can be separated from rock/sand by panning or a sluice box due to the much greater weight of gold. However, iron is rarely found as a pure metal, but as an ore that must be refined to get iron. The iron is chemically combined with something else, such as oxygen.
Why is cast iron a good metal to use for bridges?
because it's a tough matter
What is the use of metal iron?
Almost certainly, iron is our most common refined metal. Used in bridges, cans, autos, steamships, railways.
What is iron use to make?
iron is used to make bridges (i think)
What do we use iron for?
we use the metal iron to make cars, and bridges, and buildings, etc. and also to make alloys such as steel.
Why do you use iron for bridges?
The short answer is that in modern construction you would not.
What kind of metal do they use in a weight?
Iron
What metal would you use to make iron sulphate?
Iron is needed to produce iron sulphate.
What metal stick do you use when soldering iron?
That metal stick is called led
What metal would you use for the centre of an electromagnet?
iron
What a metal use to build bridges?
Bridges are almost invariably built from steel due to its high structural strength, flexibility and relatively low cost.
How do you find out if iron is a metal?
One method is to use a magnet. If the metal is iron, the magnet will be attracted.
What is the most abundant metal on the surface of the moon?
The most abundant metal is magnesium, followed by iron. Or it may be iron, depending on the source of information you use.
