These tools have assisted greatly in metals identification. Many scrap facilities now possess modern equipment, such as handheld analyzers or spectrometers. For recyclers to remain competitive, they must be able to identify various grades of scrap metal correctly. In addition to these new alloys, metals recyclers are facing heavy competition and slimmer margins. Chances are that same red brass valve has been replaced by 81 metal/semired brass or in some cases replaced by a much cheaper yellow brass. No longer can recyclers classify a valve as red brass simply because it’s a brass valve. Throughout the years, metal has changed significantly in chemistry and application. Today, it is nearly impossible to simply look at a piece of scrap metal to identify it correctly.
