Study on the Warm Compaction in Manufacturing Cu-Pb Bearing Alloy

This article deals with the manufacture of Cu|Pb bearing alloy by warm compaction technique.The results show that warm compacting temperature and pressure both have great influence on the green and sintered parts,and that the classical compacting equation is also applicable in warm compaction situation.It is also shown that Cu|Pb bearing alloy with higher density and performance than cool compacted counterpart can be obtained by warm compaction with suitable processing parameters.;
