Industrial Uses of Aluminum. 1. Aluminum is used in making cooking utensils because it is cheap, light and a good conductor of heat. ... For example, to weld together the broken ends of an iron rod, a mixture of aluminum powder and iron (III) oxide, known as thermit, is ignited. During this reaction, aluminum oxide and metallic iron are …

Iron had early medicinal uses by Egyptians, Hindus, Greeks, and Romans.[2,3] During the 17 th century, iron was used to treat chlorosis (green disease), a condition often resulting from the iron deficiency. ... Cooking, industrial processing, and storage degrade ascorbic acid and remove its enhancing effect on iron absorption.

The material we know as "steel" is an alloy of iron that contains less carbon than this: almost always less than 2%, and usually about 0.4%. Changing the amount of carbon greatly influences the properties of the material. More ductile 'wrought' iron could be made at the start of the Industrial Revolution, but only by a slow, small-scale and ...

In terms of the actual energy, it uses about 19 of the 106 exajoules (10 19 joules) input into the industrial sector each year. Iron has an embodied energy of 20-25 megajoules per kilogram (MJ/kg), which is the energy required to extract, refine, and process it. This puts the yearly energy use of attaining iron in the ballpark of 10 exajoules.

Its use in tools and weaponry did not surface until 1200 BCE when smelting, the process of extracting a metal from its ore by heating and melting it, made it a manageable material for metal workers to use. Thus, the Iron Age began. Thousands of years later, the importance of iron skyrocketed during the Industrial Revolution.

During ironmaking as well as during steelmaking, significant amounts of slag are produced. Two decades ago, more than 13 million tonne (mt) of blast furnace slag and 4 mt of steelmaking slag per annum were produced in the USA alone. It is therefore not surprising that many attempts have been made to re-use iron and steelmaking slags.

This versatility of iron-carbon alloys leads to their widespread use in engineering and explains why iron is by far the most important of all the industrial metals. History.
