Dökme demir
Dökme demir, özellikleri bileşimine ve mikroyapısına bağlı olan demir esaslı bir döküm alaşımıdır. İyi dökülebilirlik ve geniş bir sertlik, mukavemet ve süneklik aralığı ile karakterize edilir; bu nedenle makine kaideleri, gövdeler, borular, motor parçaları ve aşınmaya dayanıklı parçalar için uygundur.
