Cold working METAL LUBRICANTS Available to Purchase

A SYMPOSIUM on “Metallurgical Aspects of the Cold working of Non‐Ferrous Metals and Alloys” was recently held in London by the institute of Metals, and several of the papers presented dealt wholly or in part with the importance of lubricants in this work. We give the gist of those sections and commence first with an extract from the paper given by S. F. Chisholm M.I.Mech.E., M.I.Mar.E. (Chief Engineer, Industrial, Vacuum Oil Co. Ltd.). This paper dealt wholly with Lubricants for the Cold Working of Non‐Ferrous Metals.
