Coppor Coil vs Aluminium Coil motor, Water pump
Difference between copper coil and
aluminum coil motor.
The war between these two metals continues to rage on; both
vying to become the number one contender as the ideal component for windings in
a motor, water pump, transformer etc. Due to both metals being thermal and electrical
conductors, they often cross paths. However, it’s usually down to the
individual preferences of the person designing, or specifying, the transformer,
as to which one gets the nod.
Copper coil
Copper is a soft, malleable and ductile metal. It is a very
high thermal and electrical conductivity. Upon appearance, copper has a
reddish-orange colour.
Melting point:
1,085 °C
Boiling Point:
2,562 °C
Aluminum:
Aluminum is a soft, non-magnetic, ductile metal. It is
silvery-white in appearance and fairly reflective.
Melting Point:
660.3 °C
Boiling Point:
2,470 °C
Therefore, Copper coil is stronger than aluminum coil motor. It expands less but both materials have a similar maintenance schedule. Copper can carry almost twice the current capacity of aluminum, which makes them slightly smaller in size than aluminum wound Motor.
