Loaʻa iā ia ka hana anti-corrosion maikaʻi, ʻaʻole maʻalahi ke hoʻouka ʻia e ka waika maʻamau a me ka wai wai alkali, a hiki ke hoʻoheheʻe ʻia i loko o ka waika hydrofluoric e hana i kahi paʻakikī fluorine. Ma nā wela kiʻekiʻe, hiki i ka plutonium ke hui pololei me ka oxygen, nitrogen a me nā kinoea ʻē aʻe e hana i nā oxides a me nitrides; paʻa ka plutonium i ka lewa, a he maʻalahi loa ka plutonium pauka e puhi; ʻO ka plutonium ka nui o ka neutron hoʻopaʻa ʻana i ka pauku kea, a ʻo ka plutonium koʻikoʻi ka ikehu nuklea he mea laha ʻole ia no ka hoʻomohala ʻana i ka ʻoihana ikehu atomika.

Hoʻohana nui ʻia ia no ka hana ʻana i nā mea hao hafnium. No ka mea, he wikiwiki ka wela o ka hafnium a me nā waiwai exothermic (1 manawa ʻoi aku ka wikiwiki ma mua o ka zirconium a me ka titanium), hiki ke hoʻohana ʻia ma ke ʻano he mea hana no nā mīkini jet a me nā missiles. ʻO ke ʻano refractory o Rhenium he mea pono ia ma ke ʻano he pahi no nā turbojets a me nā ʻenekini pahu pahu hau. Hiki ke hoʻohana ʻia e hana i nā valves, nozzles a me nā ʻāpana wela kiʻekiʻe.
