Low temperature coefficient high corrosion resistance magnetic products

Ndfeb in equal neodymium iron and rich corrosion resistance is very poor, so it must be used after plating.With the expanding of the elevator motor application fields, the users  needs of resistance to corrosion of ndfeb put forward higher request. Some has put forward usage without plating. According to this situation the company developed low weightlessness ndfeb products, through continuous innovation. Under the situation of 2 atmospheric pressure, 120 ℃, 100% humidity, 168 hours weightlessness below 5 mg/cm2 (usually in 1-2 mg/cm2). And domestic enterprises need is more than 50 mg/cm2. Because of the low gravity, good corrosion resistance, therefore, to satisfy the operation of the motor and other high-end field corrosion resistance requirements, mainly used in the field of elevator, radar, such as wind turbines.
