Jul 01, 2019 Coal and Iron . Darby was the first person to use coke – a form of processed coal – to smelt iron in 1709. This advance spread slowly, largely due to the cost of coal. Other developments in iron followed, and these also used coal. As the prices of this material fell, so iron became the major coal user, increasing demand for the substance ...

Cast Iron vs Cast Steel Metal Casting Blog

Cast Iron vs Cast Steel Metal Casting Blog

Aug 04, 2021 Cast iron is often cheaper than cast steel because of the lower material costs, energy, and labor required to produce a final product. Raw steel is costlier to purchase, and it requires more time and attention to cast. When designing cast products, however, it is worth considering long-term use and replacement costs.

How Are Magnets Used to Generate Electricity Sciencing

Oct 29, 2018 Electric magnets are iron or steel wound with wire. When electricity passes through the wire, the metal becomes magnetic and creates a magnetic field. The coils of wire of the generators are conductors, and when the electrons in the wires are exposed to changing magnetic fields, they move, creating an electric current in the wires.
