Why Choose Grey Iron?
Grey iron is the most widely used cast iron due to its low cost, excellent castability, and superior vibration damping capacity. It is an ideal material for applications where high tensile strength is not the primary requirement, but stiffness, thermal conductivity, and machinability are critical.
