Resumo
© (2014) Trans Tech Publications, Switzerland.It has been studied the correlation of the obtained microstructures in cermets of Cu-Cr- Ag-Al2O3with the physical properties and the fabrication method varying the components proportions to obtain by powder metallurgy a material with good electrical conductivity and also good mechanical strength compared with pure copper allied to efficient fabrication and economical energetically process. The electrical conductivity data correspond to 40% IACS indicating that the utilized thermal treatments were relatively good for electrical contact applications and also mechanically.
