Class 180/200/220 enamel coated round copper wire is a type of winding wire made by electric round copper rod which drawn by dies with special size, then over coated with enamel repetitiously.
Magnet wire is fine copper wire that has been coated with a polymeric insulation, which is usually called “enamel," although the polymer may not actually be an enamel in the chemical sense of the word.
Maximum service temperature depends on the type of insulating polymer used. Specifications for magnet wires are given in standards such as JIS C3103; NEMA MW-1000, MW-35C, and MW-15. The most common sizes range between 25 and 44 AWG. High-purity oxygen-free (OF) copper grades are used for high-temperature applications in reducing atmospheres or in motors/generators cooled by hydrogen gas.
The OF coppers are immune to hydrogen embrittlement, which can rise when gaseous hydrogen reacts with the copper oxides found in tough-pitch coppers to form water vapor filled voids.
