We supply series of aluminum anode for defend the corrosion of steel structures in seawater. The Performance of the anode will be affected by the chemical composition of the alloy. We adopt high purity Aluminum ingot for the anodes.
The anodes are cast automatically, thus the anode alloy is uniform, free of dust and oxides. We have different alloy series to meet customer' s request:
a). YA-I series, AL-Zn-In-Si, Al-Zn-In-Ti alloy Suitable for seawater environment.
b). YA-II series AL-Zn-In-Mg-Ti Alloy
Suitable for seawater environment, specially suitable for where the fresh water and seawater mixed, and have a higher resistance.
