ʻO ka ʻeleʻele kahi ala maʻamau o ka mālama ʻana i ka ʻili kemika. ʻO ke kumu o ka hana ʻana i kahi ʻāpana o ka oxide film ma ka ʻili metala e hoʻokaʻawale i ka ea a hoʻokō i ke kumu o ka pale ʻana i ka ʻōpala.
ʻElua mau ala maʻamau o ka ʻeleʻele, ʻo ka hoʻomehana alkaline a ʻo ka ʻeleʻele wela o ka lumi. Eia naʻe, ʻaʻole maikaʻi ka hopena o ka ʻeleʻele i ka lumi wela ma ke kila kalapona haʻahaʻa. Māhele ʻia ka ʻeleʻele alkaline, a aia ka ʻokoʻa ma waena o ka ʻeleʻele hoʻokahi a me nā ʻeleʻele ʻelua.
Hoʻokumu ʻia kahi kiʻi ʻoniʻoni ʻeleʻele hao oxide ʻeleʻele maikaʻi, paʻa a me ka pala ma hope o kekahi manawa. Hoʻohana nui ʻia ia i ka uaki, pointer, hairspring, screw, instrument shell and some mechanical parts.
