Why Aluminium Windings are not being used in Motors ?

(2 Min Read)Resistivity of Copper  is 1.68 x 10-8 OhmResistivity of Aluminium 2.65 x 10-8 OhmAluminium/Copper  = (2.65 x 10-8) / (1.68 x 10-8) = 1.6    Aluminum’s resistivity is 1.6 times higher than copper’s resistivity. To compensate,...

What is Relation between Hardness,Ductility,Malleability&Brittleness...

HARDNESS:  Hardness is a measure of the material’s resistance to localized plastic deformation (e.g. dent or scratch). DUCTILITY:  Ductility measures the amount of plastic deformation that a material goes through by the time it breaks. Ductility is said...

What is Ductile to Brittle Transition...??? How it related to Titanic Sinks...???

                At low temperatures some metals that would be ductile at room temperature become brittle. This is known as a ductile to brittle transition.           The ductile to brittle transition...

What is Magnet wire?

    Magnet wire or enameled wire is a copper or aluminium wire coated with a very thin layer of insulation. It is used in the construction of transformers, inductors, motors, speakers, hard disk head actuators, electromagnets, and other applications that...
