C86300 manganese bronze is a copper-tin-zinc alloy (containing approximately 60% copper, 30% zinc, and 10% tin) used for marine and heavy-duty industrial castings requiring moderate strength and excellent corrosion resistance in seawater environments. The as-cast condition provides as-solidified properties with tensile strength around 45–55 ksi and moderate elongation, suitable for propellers, pump housings, and valve bodies where castability and seawater corrosion resistance are prioritized over maximum strength.
