ʻŌwili kila i uhi ʻia me Zn-Al-Mg (kila ZAM)

ʻO ke kila Zinc-Aluminum-Magnesium (i kapa pinepine ʻia ʻo zam coated) he huahana kila hana kiʻekiʻe i uhi ʻia me kahi hui zinc-aluminum-magnesium. ʻO ka hui uhi maʻamau he 85%–96% zinc (Zn), 5%–11% alumini (Al), a me 1%–3% magnesium (Mg), me nā ʻāpana hiki ke hoʻololi ʻia no nā noi kikoʻī. ʻO ka hoʻohui ʻana o ka magnesium e hoʻonui nui i ka mānoanoa o ka uhi ʻana a me ka hiki ke ho'ōla ponoʻī, e hāʻawi ana i kahi 2-10 mau manawa ʻoi aku ka maikaʻi o ke kū'ē ʻana i ka corrosion i hoʻohālikelike ʻia me nā huahana galvanized a me galvalume i uhi ʻia. Hāʻawi ka wili kila Zam i ka pale maikaʻi loa i nā wahi waikawa, alkaline, a me chloride-waiwai, e kōkua ana i ka hana ʻana i koho kūpono no nā kūlana ʻoihana paʻakai kiʻekiʻe, haʻahaʻa kiʻekiʻe, a me nā kūlana ʻoihana koʻikoʻi.
