Excerpt from The Technical Analysis of Brass, and Non-Ferrous Alloys IN a paper read before the American Society for Testing Materials, in 1903, Mr. G. H. Clamer, second vice-president and chemist of the Ajax Metal Company, stated that there were at that time in service of the railroads of the country on cars pounds and on locomo tiyes pounds of bearing metal. At an average price of 13 cents per pound this represented a money value of Add this to the bearing metal on engines, rolling mills, shafting and machinery of all sorts and the amount would have been easily doubled. In view of the increase in the amount of machinery and rolling stock it is safe to say that the value of the bearing metal now in use is considerably over fifty fimillion dollars. Alloys are also extensively used for machinery and parts for which the metals steel and iron, ordinarily used for such purposes, cannot be employed because of the ease with which they rust and corrode or
