Kev tsim kho tshiab:

• Hydrogen Recycling (HPMS):

UK-based HyProMag sivHydrogen Processing ntawm Magnet Scrap (HPMS) kom rho tawm thiab rov ua cov hlau nplaum los ntawm e-khoom pov tseg yam tsis muaj kev poob zoo. Txoj kev no txo ​​kev siv zog los ntawm90%vs. tsoos mining.

• Green Refining:

Cov tuam txhab xws li Noveon Magnetics ntiavCov txheej txheem tsis muaj kuab tshuaj electrochemical txhawm rau txhim kho REEs, tshem tawm cov kua qaub pov tseg thiab txo kev siv dej los ntawm70%.

 

4. Miniaturization & Precision

Teeb meem: Cov khoom siv compact (piv txwv li, wearables, drones) xav tau me me, muaj zog hlau nplaum.

Kev tsim kho tshiab:

• Bonded Magnets:

Kev sib xyaw NdFeB hmoov nrog cov polymers tsim ultra-nyias, yoog raws cov hlau nplaum rau AirPods thiab kev kho mob cog. Magnequench's bonded hlau nplaum ua tiav40% siab dua magnetic fluxnyob rau hauv sub-millimeter thicknesses.

• AI-Optimized Designs:

Siemens siv tshuab kev kawm los simulate cov duab hlau nplaum rau kev ua haujlwm siab tshaj plaws. Lawv AI-tsim rotor hlau nplaum boosted cua turbine tso zis los ntawm15%.

5. Corrosion Resistance & Lub neej ntev
