EN AC-46100 Aluminum vs. C27000 Brass

EN AC-46100 aluminum belongs to the aluminum alloys classification, while C27000 brass belongs to the copper alloys. There are 24 material properties with values for both materials. Properties with values for just one material (8, 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 EN AC-46100 aluminum and the bottom bar is C27000 brass.
