Grey
cast iron has ________.
brittleness
low
electrical conductivity
low
compressive strength
all
options are correct
low
electrical conductivity
●Grey
iron or grey cast iron is a type of cast iron that has a graphic
microstructure. It is a common engineering alloy because of its relatively low
cost and good machinability.
●It
has low electrical conductivity, high resistance to deformation and oxidation.
Hence,
the correct option is (B).
