ʻO ke kila Corten kahi kila kila i loaʻa nā kī ʻekolu mau mea nickel, keleawe a me chromium, a ʻo ka mea maʻamau he ʻano kalapona i emi iho ma mua o 0.3% ma ke kaumaha. ʻO kona kala ʻalani ʻoi aku ka maʻalahi ma muli o ka ʻike keleawe, i uhi ʻia i ka wā lōʻihi me kahi papa pale keleawe-'ōmaʻomaʻo e pale ai i ka corrosion.

Hiki ke pili i ka kaulana o Corten i kona ikaika, lōʻihi, kūpono, a me ka hoʻopiʻi nani. Ma waho aʻe o kona ikaika kiʻekiʻe, he kila haʻahaʻa haʻahaʻa loa ke kila corten.

ʻAʻole ʻeleʻele ke kila Corten. Ma muli o kona hoʻohui kemika, hōʻike ʻo ia i ke kūpaʻa kiʻekiʻe i ka corrosion o ka lewa ma mua o ke kila māmā. E ʻōpala ka ʻili o ke kila, a lilo ia i mea pale i kapa ʻia ʻo "patina."
