CC762S Brass vs. 6182 Aluminum

CC762S brass belongs to the copper alloys classification, while 6182 aluminum belongs to the aluminum 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 CC762S brass and the bottom bar is 6182 aluminum.
