CAST IRON MATERIAL AND MOTOR VEHICLE PART MADE OF THE CAST IRON MATERIAL

摘要

The invention relates to a cast iron material with lamellar graphite formation. It further relates to a motor vehicle part made of the cast iron material. In order to create a ferritic cast iron material having a higher thermal conductivity, the invention provides that, in addition to Fe, the cast iron material contains 3.9-4.2 wt% C, 0.3-0.9 wt% Si and 2.0-7 wt% Al. It has been demonstrated within the scope of the invention that, not only the thermal conductivity, but also the wear resistance and corrosion resistance of the material are increased in comparison to known cast iron materials.
