CM41 VCI paper for Ndfeb magnets
The NdFeB magnet is is a permanent magnet made from an alloy ofneodymium, iron and boron to form the Nd2Fe14B tetragonal crystalline structure. Developed in 1982 by General Motors and Sumitomo Special Metals, neodymium magnets are the strongest type of permanent magnet commercially available. The NdFeB magnet is easily get corroded due to strong chemical activity.
Shanghai Santai successfully invented the new CM41 VCI paper, which has been proved to have excellent corrosion protection against the NdFeB magnet.
