Cast iron has been used for centuries, and was used occasionally in architecture in the pre-modern period. It was in 18th century Britain that new production methods first allowed cast iron to be produced cheaply enough and in large enough quantities to regularly be used in large building projects. One of the first important projects was The Iron Bridge in Shropshire, a precedent setting structure made almost entirely of cast iron. However, it was grossly over-designed, and the makers (principally Abraham Darby) suffered financially as a result. The quality of the iron used in the bridge is not high, and nearly 80 brittle cracks are visible in the present structure. Later designers and engineers, such as Thomas Telford improved both the design and quality of the material in his bridges (for example, at Buildwas upstream of Coalbrookdale) and aqueducts (such as the world-famous Pontcysyllte Aqueduct in North Wales.)

Is cast iron different from iron?
cast iron consists of 2% - 4% of carbon in it. cast iron is pig iron remelted and thereby refined together with definite amount of limestone,steel scrap, and spoiled castings. it consists of small % of sulphur, silicon,phosphorus and manganese wrought iron is highly refined iron with a small amount of slag forged out into fibres. it consists of 99% iron. it is almost the purest form of iron. it is highly ductile,rusts extremely quickly, it cannot be heat treated
What is the the advantage of gray and white cast iron over malleable and ductile cast iron?
Gray iron with small amounts of magnesium and cesium which nodulates the graphite, resultinghigh strengthhigh ductilityWhite cast iron heat-treated to improvehigher ductility
Why dont you have to use coolant while machining cast iron?
As far as i know, coolant is not required while machining cast iron because, carbon in cast iron is present in the form of graphite (which is a cooling agent - self cooling). Moreover the carbon content is high in cast iron.
The main difference between cast-iron and steel?
Steel is an alloy of carbon and iron. If the percentage of carbon is more than 2% then it is called cast iron.
What are the weaknesses of iron?

During the manufacture of Cast Iron, an intermediate product is Pig Iron. Further processing results in Cast Iron.
What does cast iron make?
Almost everything that is called 'cast' such as; cast iron pots, cast iron centrplate (some boats use them). Until relatively recently, all engine blocks were cast iron. Most diesel engines are still cast iron.
