ʻO nā mea i hoʻohui ʻia i ke kila ʻoki manuahi ʻo S, Pb, Ca a me P. ʻO kā lākou mau hana nui penei:
1. Ke kuleana o ka sulfur
Hoʻokumu ka Sulfur i nā MnS inclusions me Mn i ke kila, hiki ke hoʻopau i ka hoʻomau ʻana o ka matrix, e maʻalahi ka haki ʻana i nā ʻāpana, a hoʻemi i ka wahi pili ma waena o nā chips a me ka mea hana. Hiki nō hoʻi i ka Sulfur ke hoʻemi i ka hakakā a pale i ka pili ʻana o nā ʻāpana i ka ʻoki ʻoki. Eia nō naʻe, hiki i ka loaʻa ʻana o ka sulfur ke hana i ke kila wela a palupalu, no laila ua kaupalena ʻia ka ʻike sulfur i ka laulā o w(s)=0.10%~0.30%, a pono e hoʻonui ʻia ka ʻike Mn e like me ia.
2. Ka hana o ke alakai
Hiki i ka hoʻohui Pb ke hoʻomaikaʻi i ka hana ʻoki ʻana o ke kila. No ka mea, ʻaʻole i hoʻoheheʻe ʻia ʻo Pb i loko o ka ferrite i ke kila a ʻaʻole i hoʻokumu i nā pūhui, aia ia i loko o kahi kūlana manuahi a hana i nā ʻāpana maikaʻi (2 ~ 3μm) i hoʻohele like ʻia i ka hoʻolālā matrix. Ke hiki aku ka wela i ka wā o ka ʻoki ʻana i ka helu heheʻe o nā ʻāpana Pb, aia ia i loko o ke ʻano hoʻoheheʻe ʻia a lilo i "lubricant" ma waena o ka mea hana a me nā ʻāpana a ma waena o ka mea hana a me ka ʻili o ka mea hana, e hōʻemi ana i ke kumu friction, ka wela o ka mea hana, a me ka lole. ʻO ka nui o ka Pb i hoʻohui ʻia aia ma ka laulā o w(Pb)=0.1%~0.35%.
3. Ka hana o ka calcium
Hiki iā Ca ke hoʻokomo i ka Ca a me Al silicate i loko o ke kila, e pili ana i ka mea hana e hana i kahi kiʻiʻoniʻoni lahilahi, loaʻa ka hopena hoʻohaʻahaʻa friction, a pale i ka ʻaʻahu o ka mea hana. ʻO ka nui o Ca i hoʻohui ʻia ma ke ʻano maʻamau w(Ca)=0.001%~0.005%.
4. Ka hana o ka phosphorus
Hoʻohui ʻia ʻo P i ke kila ʻoki manuahi me ka sulfur e hoʻoheheʻe iā ia i loko o ka ferrite, e hoʻoikaika ai i ka hoʻoikaika a me ka embrittlement e hoʻomaikaʻi i kāna hana ʻoki. I mea e pale ai i ka "ma'i anu", ua kuhikuhi 'ia ka w(P) ≤0.15%.
ʻO ka hoʻohui ʻana i kēia mau mea hiki ke hoʻomaikaʻi i ka maikaʻi o ka ʻili o ka mea hana a hoʻonui i ke ola lawelawe o ka mea hana.

Inā makemake ʻoe i ka ʻike kikoʻī hou aʻe, pono ʻoe e nīnau iā mākou no ka ʻike kikoʻī e pili ana i nā kikoʻī kikoʻī a me ka hoʻohana ʻana i kēia mau pahu kila.

Hoʻohana nui ʻia ke kila ʻoki manuahi no ka hana ʻana i nā mea kani, nā ʻāpana kiaʻi, nā kaʻa, nā mea mīkini a me nā mīkini ʻē aʻe me ke koʻikoʻi liʻiliʻi akā koi koʻikoʻi i ka nui a me ka roughness; ʻO nā ʻāpana maʻamau me nā koi koʻikoʻi e pili ana i ka pololei o ka dimensional a me ka roughness, akā haʻahaʻa haʻahaʻa i nā pono mechanical, e like me nā gears, shafts, bolts, valves, bushings, pins, pipe joints, spring seats and machine tool screws, plastic molding molds, surgical and dental surgical instruments, etc.
