Ni-Cu-Ni plating, More rust and corrosion resistance Neodymium magnet is controlled at ±0.05mm after finish slicing and plating. The material of the rack and pipe is 304 or 316L stainless steel, corrosion-resistant, and pollution-free. Finest of Magnetic Materials used meeting IMA/MMPA The standard hopper magnet is composed of a metal frame and a 25mm diameter magnetic rod arranged at a distance of 50mm from the center, then screwed and assembled or welded, can be designed with baffle or guide rod magnetic frame. The internal use of strongly magnetic materials, the surface magnetism is up to 12000GS, the standard size of the magnetic rod is ? 25 mm; the external stainless steel surface has no internal leakage and tracheotomy, and it is polished and bright. The surface of the hopper magnet can be polished to meet the requirements of food or medicine use level. The maximum working temperature of the product is ?80?. If necessary, it can also meet the special needs of customers. The maximum working temperature can reach 80?-350?. 7. Ordinary type, easy-to-clean type, guide rod or guide plate type, square type, round shape, and other special specifications required by customers can be provided. has special requirements, tolerance can beaccurately controlled at ±0.03mm
