6061 Aluminum vs. Cadmium Telluride

6061 aluminum and cadmium telluride belong to fundamentally different material chemistries. 6061 aluminum is a metal, while cadmium telluride is a ceramic material. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 10 material properties with values for both materials. Properties with values for just one material (24, in this case) are not shown. Please note that the two materials have significantly dissimilar densities. This means that additional care is required when interpreting the data, because some material properties are based on units of mass, while others are based on units of area or volume.

For each property being compared, the top bar is 6061 aluminum and the bottom bar is cadmium telluride.
