EN 2.4632 Nickel vs. 5026 Aluminum

EN 2.4632 nickel belongs to the nickel alloys classification, while 5026 aluminum belongs to the aluminum alloys. 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 2.4632 nickel and the bottom bar is 5026 aluminum.
