Nickels are made of 25% nickel and 75% copper. They’re sometimes described as bronze, cupronickel, or clad coins. The core of the coin is copper with nickel plating on top to mimic the appearance of those original silver half di(s)mes. Nickels weigh 5g and have a diameter of 21.21mm (0.835”).The density of copper (8.93 kg/dm 3 at 20 °C) varies only slightly with increasing nickel content (density of nickel at 20 °C = 8.9 kg/dm 3) and is 8.9 kg/dm3 for all Cu-Ni alloys specified in DIN 17 664.
