Khoom Description
Niobium hlau yog txias ua hauj lwm los ntawm cov ingots mus rau qhov kawg txoj kab uas hla. Cov txheej txheem ua haujlwm ib txwm yog forging, dov, swaging, thiab kos duab. Niobium hlau yog 0.010 mus rau 0.15 nyob rau hauv txoj kab uas hla muaj nyob rau hauv coils los yog nyob rau hauv spools los yog reels, thiab purity yuav mus txog 99.95%. Rau cov kab uas loj dua, thov xa mus rau Niobium Qws.
