Salt Spray Test (Neutral Salt Spray, NSS): No significant corrosion for ≥ 500 hours
酸性溶液腐蚀率 (HCl 5%)：≤0.1 mg/cm²·h
Oxidizing properties
1J67 alloy has good oxidation resistance at high temperature, and the specific parameters are as follows:
氧化速率 (900°C)：≤0.02 mg/cm²·h
Fields of application
Due to the excellent magnetic properties and mechanical properties of 1J67 soft magnetic precision alloy, it is widely used in the following fields:
Solenoid valve: Due to its high permeability and low coercivity, alloy 1J67 is an ideal material for solenoid valves.
Transformer core: High saturation magnetic induction strength and low hysteresis loss make it the preferred core material for transformers.
Precision instruments: In instruments with high precision and high reliability requirements, the stability and toughness of 1J67 alloy play an important role.
