Abstract

The invention relates to an exothermic sleeve composition comprising (a) an oxidizable metal where the oxidizable metal comprises fine aluminum as the major component, and (b) an oxidizing agent capable of generating an exothermic reaction. The invention also relates to the use of the sleeve composition to prepare sleeves, the sleeves prepared with the sleeve compositions, and the use of the sleeves to prepare metal castings.
