Important alloys, their compositions and their uses
Here is a list of Important alloys, their compositions and their uses that you should have a fair knowledge about if you are an aspirant of UPSC, SSC, or any other competitive exams.
– An alloy is a metallic intimately mixed solid mixture of two or more different elements, at least one of which is metal.
-They are homogeneous in molten state but they may be homogeneous or heterogeneous in solid state.
