Alloying effect of copper in AA-7075 aluminum composite using bale out furnace

This study investigated the effect of copper addition on AA-7075 aluminum alloy's microstructure and mechanical behavior. Aluminum alloy with reinforcement varying between 0.3 0.7 wt.% was produced using stir casting technique. The cast pre-heated at a temperature 300 °C held for 1 h before charging into bale-out furnace. Two + Cu samples were different weight percent copper. Both as-received subjected to testing after machining. surface morphology studied optical scanning electron microscopy. relevance percentage in cannot be over-emphasized strategic food processing packaging industries. result showed that higher harder composite becomes. microstructures distinct grain boundaries while rich regions silicon saturation observed alloy. had their respective tensile strength as 0.18 Mpa 0.15 hardness value 420Hv 240HVv . positively influenced by well-distributed reinforcing intermetallic phases which are fine size, although there is an observable reduction micro-segregation. Thus, enhancing properties alloys developed composites.
