neodymium trapezoid magnets

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%.
Demagnetization Curves at High Temperatures:

Grade Residual Induction (Br) Coercive Force (Hcb) Intrinsic Coercive Force (Hcj) Max Energy Product (BH)max Max Working Temp.

Application

Sintered Neodymium-Iron -Boron (NdFeB) magnets are also referred to as “neo” magnets.

They are particularly suitable for high volume production in a wide variety of shape and size. Precise dimensional control is achieved in machining processes.
