380 APPENDIX A Properties of 25 Materials Most Commonly Used in Mechanical Design A.2 PROPERTIES OF THE MOST COMMONLY USED MATERIALS The following 25 materials are those most commonly used in the design of me- chanical products; in themselves they represent the broad range of other materials. Steel and irons 1. 1020 2. 1040 3. 4140 4. 4340 5. S30400 6. S316 7. 01 tool steel 8. Gray cast iron Aluminum and copper alloys 9. 2024 10. 3003 or 5005 11. 6061 12. 7075 13. C268 Other metals 14. Titanium 6-4 15. Magnesium AZ63A Plastics 16. ABS 17. Polycarbonate 18. Nylon 66 19. Polypropylene 20. Polystyrene Ceramics 21. Alumina 22. Graphite Composite materials 23. Douglas fir 24. Fiberglass 25. Graphiteepoxy The properties of these 25 materials, given in Figs. A.1–A.12, are the proper- ties most commonly needed for design purposes. 1 Other properties can be found in the references at the end of this appendix. The properties are given as ranges, since they will depend on specific heat treatment metals and additives plastics. 1 An excellent book with more properties presented in this manner and a computer program to support material selection is M. F. Ashby, Materials Selection in Mechanical Design, 3rd edition, Butterworth Heinemann, 2005.
