Abstract：

In this study, different amounts of Ag were added into Al-Cu-Mg-Mn aluminum alloy (A206) to study the influence of Ag on its properties. The Ag content is between 0.4%-1.0% according to the A201 aluminum alloy specification. After Ag added into molten Al-Cu-Mg-Mn aluminum alloy for 60 minutes, melts were poured into the silicate bonded sand molds of separated test bars. Experimental results showed that the mechanical strength and hardness are improved by Ag additions from 0.25 wt.% to 1.00 wt.%, but the elongation is decreased slightly. After the T7 heat treatment, the mechanical strength is approximately twice as that of before heat treatment due to the precipitation hardening, and the forming of Al-Cu-Mn compound.
