Answers
Answer:
1 The Iron Age was a period in human history that started between 1200 B.C. and 600 B.C., depending on the region, and followed the Stone Age and Bronze Age. During the Iron Age, people across much of Europe, Asia and parts of Africa began making tools and weapons from iron and steel. For some societies, including Ancient Greece, the start of the Iron Age was accompanied by a period of cultural decline.
Humans may have smelted iron sporadically throughout the Bronze Age, though they likely saw iron as an inferior metal. Iron tools and weapons weren’t as hard or durable as their bronze counterparts.
2 It is certainly much stronger than bronze. This added strength meant that less steel had to be used to make effective tools, weapons or armor, making steel a lighter alternative. This strength also allows steel to hold an edge better than bronze.
3 Corrotherm supplies and distributes a wide range of nickel alloys, intended for all manner of end uses and applications within the oil and gas industry. But why are these nickel-based alloys used in such aggressive environments rather than pure metals?
The famous Aristotle quote, ‘The whole is greater than the sum of its parts,’ is particularly apt here. Alloys are a mixture of a number of different metals and other elements, each lending their own properties to the compound. Alloys can, therefore, take on these properties within the mixture, blending together the best of all the metals and elements they incorporate. More than that though, alloys can exhibit unique properties that are different to the metals they are made up of, created through the careful combination of different elements. It’s a skilled balancing act, but one that produces huge benefits.
