Our neodymium disc magnets are mainly used in holding equipment. Some small disc magnets with lower energy are also used in auto speakers.
Our neodymium disc magnets are mainly used in holding equipment. Some small disc magnets with lower energy are also used in auto speakers.
In the package industry, the bag, the magnetic jewelry, magnetic toy still have very large requirement for the disc magnets.
