The profitability of forging and stamping plants is directly related to the economical use raw materials. For sheet metal stamping, material losses can account for a significant proportion (up 20-40%), so reducing them even by few percent saves thousands tonnes metal. An indicator utilisation efficiency rationality cutting factor η, defined as ratio weight workpiece rate consumption its product...

Abstract Research into ancient Chinese metallurgy has flourished over recent years with the accumulation of analytical data reflecting needs so many archaeological finds. However, relationship between technology and society is unlikely to be revealed simply by analysing more artefacts. This particularly evident in debates sources metals used manufacture ritual bronzes Shang (c. 1500-1046 BCE), ...
