They are not, however, numbered by the metal pieces themselves but by the space in between the metal pieces. For instance, the first fret on the guitar is the space between the nut and the first metal piece. The fret wire is commonly made of a nickel/silver alloy, but stainless steel wire, although more expensive, produces longer lasting benefits.
