ʻO Chromium Metal Cube ka makana hōʻiliʻili mea nui, nā mea hoʻonaninani hale, nā mea hoʻokolohua. Hoʻohana nui ʻia nā alloys Nickel-chromium i loko o ka ʻoihana hoʻoheheʻe ʻana ma ke ʻano he mea maka no nā mea hoʻoheheʻe magnetron. -Hoʻohana maʻamau i nā mea hana ʻoki; hana i ka corrosion-kūpaʻa paʻa huila ma luna o ka ili o ke kila a me ka hao ma ka sputtering, deposition, a me kiʻekiʻe-mehana diffusion.Nickel-chromium alloys hiki no hoi ke hoʻohana 'ia e hana i ke keʻena resistors. -ʻO nā mea hoʻomehana uila kiʻekiʻe (nickel kiʻekiʻe a me ka hao-chromium-aluminum), nā mea wela kiʻekiʻe, nā'āpana kūpono, nā'āpana pale wela, nā'āpana kūikawā, nā kila kila, a me nā mea'ē aʻe, he mau mea maʻamau a hoʻohana mauʻia nā'āpana nickel-chromium. ʻO nā mea paʻa paʻa chromium (Cr) a me chromium nitride (CrN) pale maikaʻi loa i nā mea ʻenekini e like me nā apo piston, e kūʻē i ka ʻaʻahu mua ʻana a no laila e hoʻolōʻihi i ke ola pono o nā ʻāpana mīkini koʻikoʻi. Hoʻohana pū ʻia ʻo Chromium ma ke ʻano he papa hoʻopaʻa no nā uhi DLC (Diamond Like Carbon), no ka laʻana ma nā pā pākeke.

Hoʻopili:
i hoʻopaʻa ʻia i loko o ka ʻeke i ulana ʻia i ka wai, 1000kg no ka ʻeke a i ʻole e like me kāu mau koi.
Manaʻo: Hiki ke hoʻopaʻa ʻia ka haku melemele a me ka nui e nā koi o nā mea kūʻai aku.
Waihona:
E kūʻai i loko o kahi hale kūʻai maʻalili. E mālama i ke ahi a me nā kumu wela. Pono e hoʻokaʻawale ʻia mai nā oxidants a me nā waikawa, a ʻaʻole pono e hui pū ʻia

Hoʻopaʻa ʻia ke kino kino kanaka me ka ʻikepili tumorigenic hoʻokolohua. E pahū wale ka pauda i ka ea. Hoʻā a hiki ke pahū i ka lewa o carbon dioxide. ʻO ka hopena ʻino a pahū paha ke hoʻomehana ʻia me ka ammonium nitrate. Hiki ke ho'ā a hana ikaika paha me ka bromine pentafluoride. ʻO ka hopena incandescent me ka nitrogen oxide a i ʻole sulfur dioxide. ʻAʻole kūpono me nā oxidants.
