high tensile ƙarfi 99.95% Niobium waya
Niobium waya samfurin niobium ne mai tsafta mai tsafta da kashi 99.95%, wanda akafi sani da waya niobium. Danyen kayan don kera waya na niobium shine niobium mai tsafta, wanda aka yi shi zuwa kayan niobium na filamentous ta hanyoyin sarrafa filastik. Saboda kyakykyawan robobin sa a yanayin zafin daki, niobium na iya samun nakasu wajen sarrafa nakasu kamar birgima, zane, kadi, da lankwasa ba tare da dumama ba.
