FERRITIC CAST IRON MATERIAL WITH LAMELLAR GRAPHITE AND MOTOR VEHICLE PART MADE OF THE CAST IRON MATERIAL

摘要

The present invention relates to the formation of a kind of cast iron materials and flake graphite. It further relates to automotive parts by cast iron materials. In order to establish ferritic cast iron material with thermal conductivity, the present invention proposes that, in addition to iron, cast iron materials contain 3.9-4.The C of 2 weight %, 0.3-0.The Si and 2. of 9 weight %The Al of 0-7 weight %. It, which has, has been proved within the scope of the present invention, therefore not only thermal conductivity, but also the material of wearability and corrosion resistance increases, with known cast iron materials.
