PURPOSE: A balance weight material is provided to improve working efficiency for adhesion of the balance weight, to compensate the balance accurately, and to reduce the cost by automation and simplization of equipment. CONSTITUTION: A material of a balance weight is composed of an adhesive formed of wet hardening hot melt material, and a compound formed of stone powder and metal powder. The compound is selected within the range of 1-3000wt% for the adhesive of 100wt%. If the specific gravity of the mixture is 3, the adhesive of 70wt%, stone powder of 15wt% and metal powder of 15wt% are mixed. If the specific gravity of the mixture is 5, the adhesive of 50wt%, stone powder of 34wt% and metal powder of 16wt% are mixed.
