MOLYBDENUM DISULPHIDE

Abstract

IN THE last three years the wire industry has done considerable production testing with molybdenum disulphide as an additive to their wire drawing and forming lubricants, with the result that by the beginning of 1962 an estimated 70% of the U.S. mills were using molybdenum disulphide (moly) in production. The advantages reported by these mills are increased die life, brighter surface finishes, and improved products principally for the heading and wire rope industries. Other reported improvements by these mills have been higher drawing speeds or reduced force necessary to perform the drawing, less wire breakage, reduced wear on machinery, and a slower hardening rate.
