Abstract
A chill mould for the casting of light metal casting materials is provided. The chill mould is manufactured from an Ni-alloyed and/or Mn-alloyed cast iron material, of which the Ni and/or Mn content is dimensioned in such a way that the thermal coefficient of expansion of the chill mould is adjusted to the thermal coefficient of expansion of the light metal casting material, which is to be cast in each case. A chill mould is provided which can be manufactured in an economical manner which possesses optimized properties of use and at the same time allows for optimized casting results. Such a chill mould can be a constituent part of a sand casting mould for the casting of a cylinder block from a light metal casting material.
