Kubs-Magnets manufactures sintered loj samarium cobalt nplhaib hlau nplaum engineered rau cov ntawv thov kom muaj kev ruaj ntseg nyob rau hauv siab thermal loads thiab oxidative tej yam kev mob. Tsis zoo li NdFeB lwm txoj hauv kev, SmCo hlau nplaum muaj qhov sib nqus sib nqus zoo sib xws thoob plaws lub voj voog thermal mus txog 350℃thiab pom zoo ua haujlwm zoo rau thermal demagnetization.
Cov nplhaib geometries no tau ua tiav los ntawm cov hmoov hlau metallurgy, suav nrog precision tuag nias lossis isostatic nias ua raws li cov kua -theem sintering thiab meej sib tsoo kom tau raws li cov txheej txheem nruj.

Ntsiab nta
Kub coefficient ntawm residual induction ( ) tseem nyob li ntawm -0.030% / degree, yielding kwv yees flux tso zis thoob plaws kev ua haujlwm.
Muaj tsawg kawg nkaus neodymium thiab ntau dua cobalt cov ntsiab lus, tshem tawm qhov tsim nyog rau kev tiv thaiv npib tsib xee lossis epoxy plating hauv cov qauv kev ua haujlwm qhuav.
High intrinsic coercivity (Hcj) tiv thaiv cov txheej txheem flux poob thaum raug tawm tsam cov teb sib nqus los yog siab -kub spikes.
Sib nqus domains yog ua raws li thaum lub sij hawm compaction nyob rau hauv lub axial los yog diametrical vector kom concentrate flux ceev.
