1. Kālā: Ma nā ʻāpana, hoʻohana pū ʻia ke gula a me ke kālā a me ka ultrafine niobium nanopowder i kekahi manawa me he metala makamae i loko o nā ʻāpana.
2. Super alloys: he hapa nui o ka niobium i ka maʻemaʻe metala puka a i ʻole ma ke ʻano o ka niobium maʻemaʻe kiʻekiʻe a me ka niobium iron-nickel alloy, i hoʻohana ʻia i ka hana ʻana o ka nickel, chromium a me ka hao-base super alloys honua. Hiki ke hoʻohana ʻia kēia mau mea hoʻohui i nā ʻenekini jet, nā mīkini turbine kinoea, nā ʻāpana rocket, turbochargers a me nā mea wela o ka puhi ahi;
3. Steel Application: i loko o nā mea micro-alloying like ʻole i ke kila, ʻo ka ʻōpala niobium ka mea ʻoi aku ka maikaʻi o ka micro-alloying element, ʻoi aku ka nui o ke kuleana o ka niobium i ka waiwai o nā atomika hao i ka atomium niobium, hiki iā mākou ke hoʻokō i ka hoʻomaikaʻi ʻana i ka hana Steel purposes. ʻOiaʻiʻo i hoʻohui ʻia ʻo Steel 0.001% -0.1% niobium, ua lawa ia e hoʻololi i nā waiwai mechanical o ke kila;
