“Is the NdFeB magnet really eternal and not degaussing?” Professional analysis of NdFeB manufacturers
Many customers will worry about if I buy back the ndfeb magnet in the warehouse for a few months or half a year will demagnetization?
Can the magnetic pole be deranged?
Ndfeb factory for you to answer:
If the magnet's position and temperature meet the requirements, this will not happen.
If stored properly, the surface coating is not damaged, and used at the specified temperature, will not happen demagnetization, service life is eternal.
In the past 30 years, permanent magnet materials have been widely used and their market value has been greatly improved.
At present, the widely used is ndfeb magnet, it is not only in electronic products and its packaging leather is very popular, especially in the magnetic levitation industry, it is quite popular, so derived a lot of ndfeb manufacturers.
It is not a problem for professionals to distinguish the quality of ndfeb, but for non-professionals, how to choose a high-quality ndfeb magnet?
First, to see whether the raw material standards, whether in line with international standards, in order to profit, many ndfeb manufacturers in the raw material hole to reduce the cost, this will reduce the performance of ndfeb magnet, resulting in the use of its magnetic force distribution is not uniform, performance is not stable.
Second, look at the production equipment and process flow of ndfeb manufacturers, China's production of ndfeb usually adopts two pressure formation method, advanced technology can not only increase production, but also improve quality, at present, SC, HD and JM is more advanced technology.
Third, look at the size of the ndfeb magnet, size is decided by the strength of the factory and the process of teacher, because in the process of production of ndfeb, process is more complex, not a molding, by cutting and rework process, such as every industry used magnets are all different sizes and shapes, if you want to meet customer requirements of size and quality, the technology actual strength of manufacturer of ndfeb is critical.
Four, ndfeb magnet lifespan depends on its surface coating, to avoid a weakly acidic liquid corrosion and high temperature oxidation, the extended method is usually in the magnet surface electroplating, to prolong the service life of the magnet, the commonly used coating has a nickel, nickel and copper, nickel, zinc, color zinc, epoxy resin, etc., we can choose different coating according to the different needs of customers.
