  Workability Behavior of Copper–Tungsten and Graphite Composites

  By M. Navaneetha Krishnan, S. C. Vettivel, G. Karthikeyan

  Abstract: Workability is a measure of deformation that powder metallurgy materials can withstand prior to fracture occurring in the formation or upsetting process. Nowadays, copper-based sintered composites produced by powder metallurgy processes are widely used in bearings and bushes. Also composites based on copper–tungsten (Cu–W) composite containing a solid lubricant (Graphite) have been developed as self-lubricating materials under the conditions of load, atmosphere and temperature. However, it should be noted that …
