Embodiment 1
[0012] Add 12% silicon, 6% magnesium, 0.2% chromium, 0.3% titanium, 0.04% manganese, 0.1% tungsten, 0.16% ytterbium, 0.02% nickel, 0.6% zinc, and the balance aluminum into the melting furnace by weight , melted at 1050°C, and cast to obtain a wear-resistant, alkali-resistant and corrosion-resistant aluminum alloy.
Embodiment 2
[0014] Add 13% silicon, 5% magnesium, 0.14% chromium, 0.2% titanium, 0.05% manganese, 0.13% tungsten, 0.1% ytterbium, 0.03% nickel, 0.7% zinc, and the balance aluminum into the melting furnace by weight. , melted at 1000°C, and cast to obtain a wear-resistant, alkali-resistant and corrosion-resistant aluminum alloy.
Embodiment 3
[0016] Add 11% silicon, 4% magnesium, 0.1% chromium, 0.4% titanium, 0.08% manganese, 0.15% tungsten, 0.18% ytterbium, 0.026% nickel, 0.5% zinc, and the balance aluminum into the melting furnace by weight. , melted at 1100°C, and cast to obtain a wear-resistant, alkali-resistant and corrosion-resistant aluminum alloy.
[0017] Corrosion resistance test: The alloy was immersed in 1% NaOH in the corrosion medium for 1 month. The comparison experiment used Si-Mg-Al alloy with the same silicon and magnesium content, and the results were as follows: .
