Description

2.0460 (CuZn20Al2As) is a copper zinc alloy with additions of aluminium and arsenic, the latter being used as an inhibitor against dezincification. The presence of aluminium provides very good corrosion and erosion resistance in clean and slightly polluted waters, including seawater, either stagnant or relatively fast moving (up to about 3m/s). It shows the following features and properties:

High general corrosion resistance

Good strength levels
