A cast iron material and methods for using same are disclosed, as well as a method for producing and/or lining a mould. The cast iron material has a change in length at temperatures of −60° C. to 440° C., more particularly in the temperature range from 0° C. to 420° C., which change in length is as small as possible or as similar as possible to that of carbon fibre reinforced polymer or glass-fibre reinforced plastic. The cast iron material has at least the following proportions in percent by weight as elements or as compounds of carbon in the range from approximately 1.5% to 4.0%, silicon in the range from approximately 1.0% to 5.0%, manganese in the range from approximately 0.1% to 1.5%, nickel in the range from approximately 36.5% to 48.0%, chrome in the range from approximately 0.01 to 0.25%, phosphorus to approximately 0.08%, copper to approximately 0.5%, magnesium to approximately 0.150%, the remainder being iron and unavoidable impurities.
