Abstract
A metal working compound is disclosed, especially for non-ferrous metals, adapted to be applied to the metal or to an instrument for working the metal. The compound comprises a solid fat glyceride and predominantly a triglyceride having a range of properties which uniquely adapt the compound for functioning not only as a lubricant but one which, because of its properties, remains substantially at the work area of contact between the metal and instrument and is not lost due to splattering, centrifugal action, and the like.
Claims6
In a process for working a metal by contacting the metal with a working instrument and forming particles of the metal, the improvement comprising applying to at least one of said metal and instrument prior to contacting the metal with a working instrument an abrasive-free working compound consisting essentially of from 0 to about 5% by weight of a monoglyceride, from 0 to about 5% by weight of a diglyceride, and the balance substantially a triglyceride, all of said glycerides having alkyl or alkenyl moieties of from about 7 to about 17 carbon atoms, said compound being solid at room temperatures and having a melting point within the range of about 100.degree. to about 125.degree. F, a softening point within about 10.degree. F of the melting point, an iodine value number no greater than about 10, and a solid fat index at 80.degree. F within the range of about 35% to about 60%, lubricating said working of the metal by said compound which, by virtue of said properties, remains substantially at or adjacent the work area of said contact with the metal, and preventing appreciable accumulation of said metal particles on said instrument by said working compound.
