Surface roughness - aluminum vs cast iron
++
Comparing between surfaces of aluminum extrusion 6061 T6 and cast
iron, which does have suitable surface roughness if the material is
used for machining a pulley ( V-belt driving )???
Kindly give your opinion.

There are advantages and disadvantages of each. I think a better
question might be in what environment is the pulley going to be
working in. Two of the more common thoughts that come to my mind are:
Alum is a softer material and may distort with too much pressure and
especially in a hot environment. Iron, if not properly treated, will
rust in a wet environment.
