Effect of Aging Time on the Corrosion Behavior of a Cu-Ni-Si Alloy in 3.5 wt% NaCl Solution

Effect of aging time on corrosion behavior of a Cu-6.0Ni-1.0Si-0.5Al-0.15Mg-0.1Cr alloy immersed in a 3.5 wt% NaCl solution was investigated. The studied alloy exhibited good corrosion resistance compared with other super high-strength Cu-based alloys, and its corrosion resistance increased with the aging time. The purity of the copper matrix increased with precipitation and precipitates coarsening, resulting in the corrosion resistance...
