Sintered NdFeB magnets without heavy rare earth added are mainly used in the fields of wind turbine and electronics, or as diffusion substrates for high-performance magnets. The heavy rare earth free magnets grades developed by Ketian include 48SH, 45SH, 42SH, 52H, 50H, 48H, 45H, 54M, 52M, N58, N55, etc. Type of this sintered NdFeB magnet has the characteristics of low cost, high consistency, good processability, and high corrosion resistance.

Ketian has various process routes, solutions and abilities to select diffusion zones specially in grain boundary diffusion. GBD magnets are widely used in areas such as new energy vehicle main drive motors, air conditioning compressors, and intelligent robots. Typical grades contain 52EH, 50EH, 48EH, 54UH, 52UH, 50UH, 48UH, 55SH, 56H, etc. High magnetic moment consistency, high temperature stability, and low heavy rare earth content are all excellent features of this technology.

High abundance rare earth magnets mainly replace PrNd with Ce to achieve balanced utilization of rare earth resources and reduce the material costs. This kind of technology mainly used in wireless charging, industrial motors, speakers, smart home appliances, two wheeled electric vehicles, and other fields. Typical grades include 38SH, 35SH, 45H, 42H, 40H, 38H, 35H, 52M, 50M, 48M, 45M, N52, N50, etc with the characteristics of low cost and high stability.

Ketian Renewable Magnets are made from waste magnets or processing scraps and make use of oxygen free and low-carbon process. Typical grades include 38SH, 35SH, 38H, 35H, etc. Applied in industrial motors, magnetic suction, and other fields.

The high coercivity and low heavy rare earth magnets developed by Ketian are mainly aimed at wind power generation, industrial motors, automotive auxiliary motors, etc. Classic grades include 38EH, 35EH, 45UH, 42UH, 45SH, and so on. The product has the characteristics of low heavy rare earth content, low temperature coefficient, and high coercivity.

The dual alloy technology in Ketian mainly involves adding a small amount of heavy rare earths at grain boundaries to prepare magnets with heavy rare earths distributed into a complete "core shell", which improves the preparation of high-performance magnets in large blocks. Magnets with the characteristics of low weight rare earth elements, high performance, and high hcj are usually used in the fields like consumer electronics and wind turbine.
