The influence of Cu doped on structure and mechanical properties of aluminium material

Development of technology in industrial field specially automotive needs specific materials with good properties. Aluminum materials are as alternative to answer this challenge. Aluminum alloy that is being developed by Cu doped will be found the new material with good properties. In this report, we have synthesized AlCu alloy using hot mixing method. The composition of 95.1 to 96.2 wt % of Al and 3.8 to 4.9 wt% of Cu were synthesized by melting and mixing process at a temperature of 1100 °C. Analysis of the structure of x-ray diffraction data for Al-Cu showed a single phase of Al for all compositions. The mechanical properties such as hardness of highest vickers of alloy of 96.2% Al - 3.8% Cu is 80 kg/mm² for cooling in room temperature.
