Note (General): In our laboratory, cavitation erosion experiments have been carried out on various materials for about 40 years since 1970. The database was constructed and carbon steel data was analyzed in 2004. In this study, erosion resistance of cast irons, aluminum alloys, copper alloys and titanium alloys are compared with the regular carbon steels. The resistance is l/3 to l/5 lower for gray cast iron and 2/3 to 1/3 for ductile cast iron as compared with carbon steel of the same hardness. When cast irons are exposed to cavitation, graphite was removed first and the region acts as a stress raiser, and therefore the erosion resistance of cast iron is much lower than that of carbon steel with the same hardness. The resistance is 1/3 to I/5 for aluminum alloy as compared with carbon steel. Erosion resistance of aluminum alloys are lower than carbon steel, because the fatigue strength of aluminum alloys is as low as one half of the fatigue strength of carbon steel. The resistance of copper alloy and Titanium alloy is almost the same as that of carbon steel.
