Aluminum: The Element

Part I of Essay
Properties- Aluminum is the 13 element on the periodic table. It has high malleability and ductility, high electrical conductivity, high thermal conductivity, and high resistance to corrosion. Some useful alloys that are useful are aluminum bronze, alnico, and aluminum allo ....

Part II of Essay
.... It occurs most commonly as aluminum silicate or as a silicate of aluminum mixed with other metals such as sodium, potassium, iron, calcium, and magnesium. Charles M. Hall and Paul L. T. Heroult, independently and almost simultaneously found out that alumna, or aluminum oxide, would dissolve in fused cryolite (Na3AlF6) and then could be decomposed electronically into a crude molten metal. Uses- The given volume of aluminum weighs less than one-third than steel. Its high strength to weight ratio makes it very useful. We use it from foils t ....
