Salt Spray Test

The salt spray test is one of the important tests for the performance of neodymium magnets, because neodymium magnets have the disadvantage of being easy to corrode and oxidize. Long-term exposure of neodymium magnets to salt water, salty air or harsh chemicals will accelerate corrosion.
Generally speaking, most factories can only provide salt neutral spray test for 72 hours. And we can provide neodymium magnets with 216 hours of salt spray. And our most frequently produced magnets can easily pass the 200 hour salt spray test.

The salt spray test has a great relationship with the coating, and different coatings have different corrosion resistance. And among many of the most commonly used coatings:

salt spray test magnet
Salt Spray Test 216 Hours (Neodymium Magnet)

Epoxy Salt Spray Test:
Advantages: good protection performance, relatively good price
Disadvantages: In the control of thickness, it is not as good as parylene

Parylene Salt Spray Test:
Advantages: the best protection performance, easy to control the thickness,
Disadvantages: Reduce sticker viscosity, easy to fall off from sticker, high price

There are currently three main mainstream salt spray tests, which are used to simulate different times.
Neutral salt spray test performed for 24 hours equates to approximately 1 year in a natural environment.
Acetic acid salt spray test performed for 24 hours equals 3 years in a natural environment.
Copper salt accelerated acetate spray test performed for 24 hours equals 8 years in a natural environment.
All of these types are accelerated tests to determine the corrosion resistance of paints and varnishes, metal products, lubricants, protective fluids and any other objects that will be used in harsh climatic conditions.
