Why was wrought iron used for the Eiffel Tower?
Eiffel Tower fun facts Gustave Eiffel used latticed wrought iron to construct the tower to demonstrate that the metal could be as strong as stone while being lighter.
What is puddled iron Eiffel Tower?
The Eiffel Tower is made of puddled iron, a type of refined cast iron that was the precursor to modern steel. Pig iron produced from ore in blast furnaces is then refined by “puddling” or heating in a furnace and stirring to oxidize. The puddling process removes excess carbon to create almost completely pure iron.
Is the Eiffel Tower cast iron or wrought iron?
The Eiffel Tower was constructed with puddled iron, a kind of wrought iron. The puddled iron (wrought iron) of the Eiffel Tower weighs 7,300 tonnes, and the entire structure, including non-metal components, weights approximately 10,000 tonnes.
Is the Eiffel Tower made of Algerian iron?
Origin of the iron. The iron that was used to build the tower is not just any, of course. It was the subject of a careful choice. It was bought at a factory in Meurthe-et-Moselle and comes from Algerian mines.
Why is wrought iron called?
Wrought iron is tough, malleable, ductile, corrosion resistant, and easily welded. It was given the name wrought because it was hammered, rolled or otherwise worked while hot enough to expel molten slag. The modern functional equivalent of wrought iron is mild steel, also called low-carbon steel.

What is the Eiffel Tower known for?
The Eiffel Tower—or as the French call it, La Tour Eiffel—is one of the world’s most recognizable landmarks. The tower was designed as the centerpiece of the 1889 World’s Fair in Paris and was meant to commemorate the centennial of the French Revolution and show off France’s modern mechanical prowess on a world stage.
Is wrought iron black?
What is wrought iron? Mild steel that has been machine-bent into shape in a cold state or cast steel and iron pieces that have been painted black are both regularly mislabelled as wrought iron work.
What kind of metal is the Eiffel Tower made of?
The cast iron produced in blast furnaces by reducing iron ore is then refined by an operation called puddling, which removes the excess carbon still present in the cast iron. The result is almost pure iron.
Why is the Eiffel Tower still as dazzling as ever?
One of the reasons the Eiffel Tower is still as dazzling as ever is because it adapts to its environment and all types of weather conditions: wind, cold, rain, snow, frost, heat, etc. Like any metal, puddled iron is sensitive to variations in temperature and so reacts to high temperatures in summer and low or even negative temperatures in winter.
When was the Eiffel Tower built and by who?
During the World’s Fair in 1889, Contractor Gustave Eiffel introduced the Eiffel Tower. An engineer by training, Eiffel founded and developed a company specializing in metal structural work.
Why does the top of the Eiffel Tower lean?
The sun only hits one of the 4 sides of the Tower creating an imbalance with the other 3 sides, that remain stable, thus causing the Eiffel Tower to lean. In this way, the sun’s movement over the course of a clear day can cause the top of the Tower to move in a more or less circular curve measuring approximately 15 centimeters in diameter.
