Comprehensive Study for Ternary Alloys of Al-Cu-Sn and Al-Cu-Zn with Testing Compression and Corrosion.

Cast ternary alloys are significantly considered to be studied. For example, aluminum (Al), copper (Cu), and tin (Sn) construct the ternary alloy of Al-Cu-Sn. Another example is the aluminum (Al), copper (Cu), and zinc (Zn), which construct the ternary alloy of Al-Cu-Zn. Each one of them is established under the condition of very high temperatures. Their elements are collected, adjusted, and chopped. So, the ternary cast alloys are manufactured. Then, important mechanical tests of compression and corrosion are carried out and compared. The compression test is conducted on each alloy of Al-Cu-Sn and Al-Cu-Zn. It can be yielded that the highest compression value is recorded as Zn=0% and Sn=0%, but the lowest compression value is reported as Zn=10% and Sn=10%. On the other hand, the influence of corrosion tests on both alloys is found to be insignificant. Key findings of compression results, which are tied to Zn/Sn concentrations, are that when Zn=0% and Sn=0%, brittle status has been confirmed, while when Zn=10% and Sn=10%, ductile status has been approved.
