    Tantalum & Niobium

    Tungsten hnyav alloys (WHAs) tau tshwm sim los ua cov khoom ntawm kev xaiv rau kev siv hauv ntau yam kev lag luam vim lawv cov khoom tshwj xeeb, xws li siab ceev, siab zog, siab cuam tshuam lub zog thiab corrosion kuj, thiab lwm yam. Feem ntau, Ni raws li binders xws li Ni-Fe, Ni-Cu, thiab lwm yam yog siv los sib sau ua ke WHAs.
