| Abstract: | The effects of copper content on the physical and mechanical properties of powder metallurgy airplane brake materials were studied. The results show that the density, porosity, hardness and compressive strength are influenced by the copper content through the alloying and precipitation hardening of copper in iron. The optimum content of copper is 30%. |
