Au, Ag, Cu......2N, 3N, 4N, 5N,......Huh??? >>>>>

>>>>> While I think I have a grasp on the different alloys used to produce 18K gold in its Yellow, Pink (Rose/Red), and White iterations, I often see the various alloys followed by a class number such as 2N, 3N, or 5N.
Can anyone tell me what these class numbers mean?
Someone was kind enough to answer, but I'm still not clear on their relationship to watch cases.
Any help for this metallurgically challenged WIS?
0N: 30%+ Ag, 10% Cu
2N: 16% Ag, 9% Cu
3N: 12.5% Ag, 12.5% Cu
4N: 9% Cu, 16% Ag / 99.99% Au (obviously not the meaning when watch related)
5N: 20% Cu, 5% Ag / 99.999% Au

Some help...........
2N is yellow gold (9% Cu, 16% Ag, 75% Au) 3N is also a yellow gold (12.5% Cu, 12.5% Ag, 75% Au) 5N is pink gold (20% Cu, 5% Ag, 75% Au) AP says they use 2N EXCEPT for the ultra complicated models where they use a 3N alloy. I believe 3N has a bit more bras...
