12L14 Pā kila ʻoki manuahi

A kila me ka nui o ka sulfur a me ka phosphorus ma mua o ka maʻamau i manaʻo ʻia no ka hana ʻana i nā ʻāpana no nā mīkini mīkini wikiwiki a me nā mīkini semi-automatic. Hana ʻia ke kila ʻoki manuahi ma ke ʻano o nā koʻokoʻo, a loaʻa iā ia he 0.08–0.45 pakeneka kalapona, 0.15–0.35 pakeneka silika, 0.6–1.55 pakeneka manganese, 0.08–0.30 pakeneka sulfur, a me 0.05–0.16 pakeneka phosphorus. ʻO ke kiʻekiʻe o ka sulfur e alakaʻi i ka hoʻokumu ʻia ʻana o nā inclusions (no ka laʻana, manganese sulfide) i waiho ʻia ma ka ʻaoʻao o ka palaoa. Hoʻomaʻalahi kēia mau inclusions i ka ʻoki ʻana a paipai i ka wili ʻana a me ka maʻalahi o ka hoʻokumu ʻana o nā ʻāpana. No kēia mau kumu, i kekahi manawa ua hoʻohui ʻia ke kila ʻoki manuahi me ke kēpau a me ka tellurium.

ʻO 12L14 kahi ʻano kila kalapona i hoʻoulu hou ʻia a hoʻoulu hou ʻia no nā noi ʻoki manuahi a me ka mīkini. Loaʻa i ke kila kūkulu (kila hana) ka mīkini maikaʻi loa a me ka ikaika haʻahaʻa ma muli o nā mea hoʻohuihui e like me Sulfur a me Lead, hiki ke hōʻemi i ke kū'ē ʻoki a hoʻomaikaʻi i ka hoʻopau a me ka pololei o nā ʻāpana i mīkini ʻia. Ua hoʻohana nui ʻia ke kila 12L14 i ka hana ʻana i nā ʻāpana mea hana pololei, nā ʻāpana kaʻa a me nā ʻāpana koʻikoʻi o nā ʻano mīkini like ʻole, nā noi maʻamau e pili ana i nā bushings, nā ʻauamo, nā mea hoʻokomo, nā couplings, nā fittings a me nā mea ʻē aʻe.
