1080A Aluminum vs. EN 2.4951 Nickel

1080A aluminum belongs to the aluminum alloys classification, while EN 2.4951 nickel belongs to the nickel 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 1080A aluminum and the bottom bar is EN 2.4951 nickel.
