**The Effect of Pouring Temperature on the Nature of Toughness of Impact and Hardness of Aluminum Screws Plus 5% Silicone**

Introduction

The aluminum pouring of the screw plus 5% silicone is an important process in the world of material engineering. In this study, the variation of the pouring temperature of 680 ° C, 700 ° C, 720 ° C, 740 ° C, to 760 ° C was examined to determine its effect on the nature of the toughness of the impact and aluminum hardness. Aluminum screws used come from used cans, especially the lid which has an aluminum content of around 90%. This study aims to understand how the temperature of the pouring can affect the mechanical characteristics of aluminum that has been recycled.

The Importance of Aluminum Recycling

Aluminum recycling has many benefits, especially in reducing waste and increasing the efficiency of resource use. However, the recycling process can reduce the mechanical properties of the material. Therefore, the addition of elements such as silicon, copper, magnesium, iron, manganese, and zinc are needed to improve the mechanical properties of aluminum. Silicon, for example, is known to increase toughness and reduce the fragility of aluminum alloys.

The Role of Silicon in Aluminum Alloys

Silicon is a key element in improving the mechanical properties of aluminum alloys. It is known to increase toughness and reduce the fragility of aluminum alloys. The addition of silicon to aluminum alloys can also improve their corrosion resistance and weldability. In this study, the effect of silicon on the mechanical properties of aluminum screws plus 5% silicone was examined.

The Effect of Pouring Temperature on Impact Toughness

The results showed that the impact toughness value reached the maximum at the pouring temperature of 700 ° C with a value of 19.13 joules. However, the toughness of this impact has decreased along with an increase in the temperature of the pouring. This indicates that the pouring temperature plays an important role in determining the mechanical properties of aluminum screws plus 5% silicone.

The Effect of Pouring Temperature on Hardness

Likewise, the violent test shows the maximum value at the same temperature, which is 72 bhn. This indicates the relationship between the temperature of the pouring and the mechanical properties of the aluminum that is done. The results of this study show that the pouring temperature has a significant effect on the hardness of aluminum screws plus 5% silicone.

The Relationship Between Pouring Temperature and Porosity Defects

It is important to record that at higher pouring temperatures, porosity defects increase. From the results of microstructure observations, it appears that at a temperature of 700 ° C, the porosity defect is not too much and shows the best results compared to other temperatures. Conversely, at temperatures 680 ° C, 720 ° C, 740 ° C, and 760 ° C, porosity defects increase, potentially affecting the strength and durability of the material.

Conclusion

From this study, it can be concluded that the temperature of the pouring plays an important role in determining the mechanical properties of aluminum screws added with 5%silicone. In addition, this research also provides valuable initial data for the use of aluminum screws as technical material. These findings can be used as a reference for further research and provide practical knowledge for researchers and engineers in the field of material.

The Importance of Controlling the Casting Process

Overall, this research not only provides an understanding of the mechanical properties of aluminum that has been recycled, but also emphasizes the importance of controlling the process in casting to achieve the desired material quality. This is very useful for industries that require materials that have optimal toughness and violence.

Recommendations for Future Research

This study provides valuable initial data for the use of aluminum screws as technical material. However, further research is needed to fully understand the effect of pouring temperature on the mechanical properties of aluminum screws plus 5% silicone. Future research should focus on examining the effect of pouring temperature on the microstructure and mechanical properties of aluminum screws plus 5% silicone.

Limitations of the Study

This study has several limitations. The first limitation is that the study only examined the effect of pouring temperature on the mechanical properties of aluminum screws plus 5% silicone. Further research is needed to examine the effect of other factors, such as the composition of the aluminum alloy and the casting process, on the mechanical properties of aluminum screws plus 5% silicone.

Conclusion

In conclusion, this study provides valuable initial data for the use of aluminum screws as technical material. The results of this study show that the pouring temperature plays an important role in determining the mechanical properties of aluminum screws added with 5%silicone. This research also emphasizes the importance of controlling the process in casting to achieve the desired material quality.
