I think K is the most common. Looks like stainless steel and machines about the same. These two are the only copper/nickel alloys that are called Monel. There are a lot of other copper/nickel alloys. Monel has more nickel than copper. When the copper content gets higher the color changes toward copper. Probably at least 400 alloys of copper with nickel, aluminum, zinc, tin, magnesium with various names but there are only two that are called Monel as far as I know. 04-28-2008, 03:46 PM #20.
