What are the uses of alloys in daily life and how are alloys made? |
[Edit] |
Just about every single piece of metal that you come into contact with on a daily basis is an alloy of some kind. There are very few pure metals used for anything. Alloys are made with far superior characteristics than the raw metals they are made from. Steel is a obvious example (an alloy of iron).
I don't know much about how they make alloys though... anybody else?
Answer
Alloying is not always done to produce a 'superior' material, but to produce materials having a derired requirement in the industry or elsewhere. A classic case is of lead solder (containing lead & tin), in which the melting point of the constituent elements are lowered, not necessarily a desirable property.
Alloying can be carried out using hot press method (a sheet of material is sandwiched with alloying material), rolling the heated base metal in a drum full of alloying metal powder, using hot spraying, galvanizing (dipping the base in a molten solution of alloying material) etc. Sometimes the alloying material is addded in small proportions to the molten base metal (eg, in production of different types of steel)
cheers!
