Why do sintered NdFeB magnets need a salt spray test
Some people don’t know what is the salt spray test of NdFeB magnets, and why do they need to do salt spray test, let’s find out today.
NdFeB magnets are widely used in the industrial field. The working environment is not so comfortable. The harsh working environment will corrode NdFeB magnets. There is what we call the salt spray test.
Some NdFeB magnets do not need a salt spray test, but some industries require NdFeB magnets to undergo a salt spray test for 48 hours or 72 hours, such as some electronic components and some industrial products. Such an experiment is needed.
If we are not at ease with the coating on the surface of the NdFeB magnet when we buy the NdFeB magnet, we can contact the merchant to conduct the salt spray experiment.
