What are the uses of alloys in daily life and how are alloys made?
Ans) Alloying is not always done to make a 'superior' material, but to produce materials having a desired requirement in the industry or elsewhere. A classic case is of lead solder (having lead & tin), in which the melting point of the constituent elements are lowered, not of necessity a desirable property.
Alloying can be carried out using hot press process (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 added in small proportions to the molten base metal (e.g., in production of dissimilar types of steel).
