Nā hiʻohiʻona waiwai: He kila puna kalapona i hoʻohana nui ʻia, ʻoi aku ka ikaika, paʻakikī, elasticity, a me ka paʻakikī i hoʻohālikelike ʻia me 65 kila. ʻO ke anawaena hardenability koʻikoʻi he 30-50mm i ka wai a me 16-32mm i ka aila. Loaʻa iā ia ka naʻau i ka overheating a me ke ʻano o ka huhū brittleness i ka wā o ka mālama ʻana i ka wela, a ua maʻalahi i ka haki ʻana i ka wā e kinai ana i ka wai. Hoʻohana pinepine ʻia ka ʻaila kinai. He kūpono ka hoʻopau ʻana i ka wai no ka nui o ka pauku ma mua o 80. ʻO ka hoʻoluʻu ʻaila: Ma hope o ka hoʻoheheʻe ʻana, maikaʻi ka ʻoki ʻana, akā haʻahaʻa ke anuanu deformation plasticity, a maikaʻi ʻole ka hana kuʻi. Hoʻohana mau ʻia kēia kila ma hope o ke kinai ʻana a me ka hoʻoulu ʻana i ka mahana wela. 3-16
