Abstract
This study examines the impact of adding different ratios of alumina (Al2O3) and nanocopper (Cu) materials to dental amalgam alloy (Ag-Sn-Cu) on their physical, microstructural, and mechanical properties.The study utilized powder metallurgy and compaction techniques to prepare dental amalgam samples.The scanning electron microscope (SEM), and mechanical tests (compressive strength) were used to determine the microstructure, density, and mechanical properties.Various ratios (2.5, 5, and 10 wt.%) of nano-copper and alumina have been added to the amalgam capsules.The findings indicated that when the proportion of nano copper particles rose to 10 wt.%.The compressive strength of amalgam declined.This drop in characteristics could be linked to the malleability of copper.Conversely, dental amalgam specimens containing alumina (Al2O3) demonstrated strength, especially with 5wt.% alumina, in comparison to the amalgam sample.The enhancement in strength in these samples can be attributed to the high hardness and rigidity of alumina whereas the decline in strength in samples with 10 wt.% copper can be attributed to the flexibility of copper, versus alumina.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
