An extraordinary dezincification corrosion resistance of 71 wt.% Cu-Zn alloy is designed by adding Al 2 O 3 nanoparticles. The dezincification corrosion resistance, weight loss per unit, microstructures are investigated to reveal the effect of Al 2 O 3 nanoparticles on the modification of 71 wt.% Cu-Zn alloy. Results indicate that: The average depth of dezincification corrosion resistance is decreased by 41.38% and weight loss per unit is decreased by 70.88% by adding Al 2 O 3 nanoparticles. Grains are refined and more uniformly distributed to enhance the dezincification corrosion resistance. The temperature of phase transition and melting point are decreased by 67.9 °C and 72.9 °C to gain the higher dezincification corrosion resistance, respectively.
