This work aims to investigate the behavior of \(Al-12Si-xTe\) alloys that are fabricated by the casting method due to the importance of Al-12Si alloy in many industries. Tellurium metal was added with three weight percents (1, 2 and 3%) and the characterization of these produced alloys was done by XRD analysis to identify the formation of hard \({Al}_{2}{Te}_{3}\) phase, which refining the grain size in a base alloy. SEM examination also confirmed the refining and uniformity distribution of \(Te\) within \(\alpha -Al\) matrix and eutectic\(Si\). From AFM analysis can be seen that 2 and 3 wt% of \(Te\) gave lower surface roughness compared with base alloy, while \(Al-12Si-1Te\) alloy gave the highest ratio of the interfacial area due to heterogeneity between matrix and \(Te\) clustered particles. The refining of produced alloys led to the difference in main diameter that increased after \(Te\) addition as illustrated from AFM analysis and so the \(Te\) addition gave more theoretical wear resistance. Corrosion measurement showed that 2 and 3 wt% of \(Te\) gave different behavior for cathodic and anodic regions and decreasing in the corrosion rate to 0.0033 and 0.0479 mm/y respectively compared to base and \(Al-12Si-1Te\) alloys due to formation of \({Al}_{2}{Te}_{3}\) phase as sufficient cathodic area.
