A enameled wire having 100 parts by weight of a polyamide-imide resin, 1 to 5 parts by weight of a lubricant, 1 to 200 parts by weight of a masking agent-stabilized isocyanate, and 1 to 30 parts by weight of a silane coupling agent are dissolved or dispersed in a solvent to prepare a coating composition. The coating composition is then coated directly or through other insulator on the circumference of a conductor, and the coating is then baked to form a lubricating layer.

Self-lubricating enameled wire

A wire for a wire saw apparatus for slicing a material includes an element wire, a binder coated on an outside circumferential surface of the element wire, and abrasive grains dispersed in the binder. The element wire is a high tensile strength metal wire, the binder is a material such as an organic or inorganic material other than a metal, and the abrasive grains are held on a surface of the element wire by the binder. The element wire is also made by either a natural quartz glass or a high purity synthesis quartz glass.
