The SST results differ from coating. In general, Salt Spray Test result for the magnets with barrel plating (normally for small size of magnets), is better than the ones with rack plating (normally for big size of magnets).2. Salt Spray Test (SST) condition: 5% NaCl, 35°C, continuously spray a certain time, test whether there is corrosion on plating/coating surface.3. Pressure Cooking Test (PCT) condition: 2 atm, 95% RH (Relative Humidity), 121°C to test the plating/coating adhesion. (Zinc, Passivated/Phosphated, and Epoxy not suitable for PCT).4. Other test methods for plating/coating: Drop Test, Cross Cut Test, Heating and Spilling Test, Constant Temperature, Humidity Test, etc. Physical Properties of Neodymium MagnetsCurie Temperature (°C)310~380Maximum Working Temperature (°C)80~230Electrical Resistivity (μ.cm)110~170Hardness (Hv)560~580Density (g/cm3)7.4~7.8Relative Recoil Permeability (μrec)1.05Saturation Field Strength (kOe/kA/m)(30-40)/(2,400-3,200)Temp.
