  • Patent number: 5498351
    Abstract: A a process for making a lubricious composition useful for preventing seizing of threaded fasteners in application to the threaded surface(s) thereof, comprising: (a) forming metal wire by drawing of metal source material through a wire drawing die; (b) lubricating the wire drawing die with an oil lubricant in forming the metal wire, to produce as a by-product thereof a metal flake/oil mixture; (c) separating the metal flake/oil mixture to recover a metal flake/oil suspension; and (d) formulating the metal flake/oil suspension in a metal flake-containing lubricant composition. The invention in another aspect relates to a product of such process. In a specific compositional aspect, the invention relates to a composition comprising an oil-based vehicle, 15%-35% by weight particulate metal (e.g., microscopic flake aluminum), based on the total weight of the composition, and 10%-30% by weight graphite, based on the total weight of the composition.
