Sintered 6061 Aluminum vs. C70700 Copper-nickel

Sintered 6061 aluminum belongs to the aluminum alloys classification, while C70700 copper-nickel belongs to the copper alloys. There are 28 material properties with values for both materials. Properties with values for just one material (3, 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 sintered 6061 aluminum and the bottom bar is C70700 copper-nickel.
