Cube/Block 5.0 x 5.0 x 5.0 mm N35SH Nickel (Ni+Cu+Ni) Neodymium Magnet 1.High intensity NdFeB magnet in a variety of shapes. 2.grades:N33-N52 (M,H,SH,UH,EH) 3.platings:Nickle,Zinc,Cu,etc. NdFeB magnets are the most powerful and advanced commercialized permanent magnets available today. Honsen Magnetics has more than 10 years of experience in this field. We concentrate on Sintered NdFeB magnets and develop them with the help of an experienced engineer and a dedicated sales team. * Physical advantages: This material is hard,brittle, and easily corroded, but we have many surface treatments to protect the surface, such as Nickel,Nickel-Copper-Nickel,Znic,Black&Grey epoxy coating,Aluminium coating,Tin,Silver, and so on. It has high stability even at high temperatures; the working stability is less than 80 degrees Celsius for low Hcj and more than 200 degrees Celsius for high Hcj. The temperature coefficients of Br are -0.09--0.13% and Hcj are -0.5--0.8%/degree C.
