Qsn6.5-0.4 has high strength, elasticity, wear resistance and diamagnetization, good pressure processing under hot and cold states, high fire resistance to electric spark, welding and brazing, good machinability, corrosion resistance in air and fresh water. Because of high phosphorus content, its fatigue strength resistance is high, elasticity and wear resistance is good, but in hot processing has hot brittleness, can only accept cold pressure processing.
