1.The above-mentioned data of magnetic properties and physical properties are given at room temperature.

2.The max working temperature of magnet is changeable due to length-diameter ratio,coating thicness and another environment factors

Product Advantages                                                                             

1.High corrosion resistance and low weight loss products

There are two main standards of low weight loss test as follows:

1. USA PCT: 121±1℃, 2 atm, 95% RH, 96 hours, weight loss less than 5~10mg/cm2

2. Europe HAST: 130±2℃, 3 atm, 95% RH, 168 hours, weight loss less than 2~5mg/cm2

Due to special material formulation and manufacturing process, the corrosion resistance is so excellent that magnets can reach the strict testing requirements above. These magnets are widely used in elevator, wind generator, military and aerospace industries.

2.High temperature stability products

With higher Hcj value, these magnets are more stable during high temperature. The tests show that the maximum permanent loss after aging is 5%.
