Hana ʻia nā wili ʻoihana i nā ʻano like ʻole a me nā kūlana. Loaʻa i nā mea hao kila kahi hiki ke hoʻokuʻu i nā kaumaha kiʻekiʻe loa ma lalo o ka mana o ka mālama ʻana i ka wela, e alakaʻi ana i ke koho ʻana o kēia mea hao i ka wā e hana ai i nā wili kila i hoʻohana ʻia i nā hale ʻoihana. Loaʻa i nā kila Ferroalloy kahi ʻike kalapona kiʻekiʻe a ʻoi aku ka nui o nā waiwai ma mua o ka hao maʻemaʻe, he palupalu loa ia. ʻOiaʻiʻo, me ka hoʻohui ʻana i ke kalapona, loaʻa nā hui hoʻopaʻa e like me ka manganese, silicon, sulfur, phosphorus, a i kekahi manawa ʻo vanadium (hoʻohui ʻia ka vanadium i nā hui kila e pono ai ka elasticity) i nā hui kila.
I loko o ka ʻoihana kūkulu hale, hoʻohana nui ʻia nā wili a me nā nati kūkulu i ka hana ʻana o nā hale kōlea, nā alahaka, nā pā a me nā mea kanu mana. ʻO ka ʻoiaʻiʻo, hana ʻia ka hoʻohana ʻana i nā wili a me nā nati kūkulu ma ke ʻano ʻē aʻe ma o ka hoʻopili ʻana i nā metala, ʻo ia hoʻi nā wili kūkulu a i ʻole ka hoʻopili ʻana i ka arc me ka hoʻohana ʻana i nā electrodes, ma muli o ka pono e hoʻohui i ka papa kila a me ke kaola. Loaʻa i kēlā me kēia ʻano pili kona mau pono a me nā hemahema, a mākou e nānā ai ma lalo nei.
ʻO nā wili kūkulu i hoʻohana ʻia i nā pilina kaola hale i hana ʻia me ke kila kiʻekiʻe, ʻo ka maʻamau he 10.9. ʻO ke ʻano o ka papa 10.9 ʻo ia hoʻi ka nui o ka ikaika tensile o ka wili kūkulu ma kahi o 1040 N/mm2, a hiki iā ia ke kū a hiki i ka 90% o ka nui o ke kaumaha i hoʻopili ʻia i ke kino wili ma ka ʻāpana elastic me ka ʻole o ka deformation mau loa. Ke hoʻohālikelike ʻia me ka hao 4.8, hao 5.6, kila maloʻo 8.8, ʻoi aku ka ikaika tensile o nā wili kūkulu a ʻoi aku ka paʻakikī o ka mālama wela i ka hana ʻana.
ʻOkoʻa mai nā ʻōwili hexagon maʻamau a me nā nati, hana ʻia nā ʻōwili hexagon maʻamau a me nā nati e like me ke kūlana DIN931 ma ke ʻano he hapalua kia, e like me ke kūlana DIN933 ma ke ʻano he mau kia piha, a he maʻalahi nā wili hexagonal, hana pinepine ʻia e like me ke kūlana DIN6914. ʻOi aku ka ʻiʻo a me ke kiʻekiʻe o nā nati hoʻopili ma nā wili kūkulu ma mua o nā nati hex maʻamau i hana ʻia i DIN934, e hōʻike ana i ke kūpaʻa koʻikoʻi kiʻekiʻe, i hana ʻia i DIN6915. Ua hōʻailona ʻia nā wili o kēia kūkulu ʻana he 10HV a he maʻamau ka matt black phosphating no ka hoʻomaikaʻi ʻana i ka pale ʻana i ka popo kaiapuni a i ʻole ka galvanized wela a i ʻole ka chrome hohonu matt silver, ʻelua me kahi hoʻopau metala. Hoʻohana ʻia lākou i ka zinc a he kūpaʻa maikaʻi i ke kaiapuni.
