Fatigue Strength
Fatigue strength is the maximum stress value that a material can withstand without fracture under 10^7 cycles of load, and it is related to the state of the selected material. Usually, the fatigue strength is about 1/3 of the tensile strength. For fine-grained solid solution alloys, the fatigue strength can be increased to 1/2 of the tensile strength.

Corrosion Resistance
H96 has excellent corrosion resistance in dry air and freshwater environments. It has good corrosion resistance in environments containing chlorine, ammonia, or strong acids and alkalis, but due to the presence of a small amount of zinc, slight dezincification corrosion may still occur. Surface treatment (such as plating, passivation) can further improve corrosion resistance.
