The present invention relates to a aluminum ingot divider which is cast by a new iron-based rare-earth high chromium cast iron. It belongs to the domain of metal cast and jointing. The characteristic is: The noumenon of the divider is casted holistic way. The stuff of the noumenon of the divider and steel nature material which flow Al is low carbon, middle carbon, high chromium, low nickel and add rare-earth. It can obtain austenite, ferrite-region and carbide which exist together in two phases in cast condition. The component is: C: 0.25 -0.50%, Cr: 15 - 28%, Ni: 1 - 7%, Si: 0.40 - 1.20%, Mn: 0.40 - 1.20%, S is less than or equal to 0.05%, P is less than or equal to 0.05%. Add 0.1 - 0.3% rare-earth silicon iron alloy of Baotou 1# when it is about to leaves to the stove. The rest is ferroguinous and impurity in the condition of fuse. In this invention, the divider is hard to bend when circulated; the divider and the steel nature material which flow Al are able to bear high temperature, corrosion and scour. It
