### Ceramics for Strength San Jose Delta

For a metal, the compressive strength is near that of the tensile strength, while for a ceramic, the compressive strength may be 10 times the tensile strength. Alumina, for example, has a tensile strength of 20,000 psi 1138 MPa), while the compressive strength is 350,000 psi (2400 MPa). The discrepancy between tensile and compressive strengths is in part due to the brittle nature of ceramics
