This paper focuses on appropriate selection of material for manufacturing of rocket motor case used in aerospace applications. Motor case should be light weight, stiff, strong, resistant to crack growth and allows minimum heat flux. Initially, respective properties and material indices have been derived by making certain assumptions. The appropriate range of materials has been identified in first step with help of derived material indices. These material indices are plotted in Cambridge Education System software with their appropriate slopes. By finding and putting the appropriate slopes the suitable materials are screened. These screened materials are further analyzed by novel heuristical approach. Finally, material/s is proposed for manufacturing of rocket motor case on the basis of analysis supported by available literature.
