Nānā:
1. Brinell paakiki: Hoʻohana nui ia e ana i ka paʻakikī o ka hoʻolei ʻana, forgings, non-ferrous metala ʻāpana, hot-rolled billets a me nā ʻāpana annealed. ʻO ≥HB450 ka laulā ana.
2. ʻO ka paʻakikī Rockwell: Hoʻohana nui ʻia ʻo HRA no nā specimens paʻakikī kiʻekiʻe e ana i ka paʻakikī o ka ʻili o nā mea a me nā ʻili me ka ʻoi aku ka paʻakikī ma mua o HRC67, e like me ka cemented carbide, nitrided steel, etc. ʻO ke ana ʻana ʻo HRA>70. Hoʻohana nui ʻia ʻo HRC e ana i ka paʻakikī o nā ʻāpana kila (e like me ke kila kalapona, ke kila kila, ke kila kila, a me nā mea ʻē aʻe) ma hope o ke kinai ʻana a i ʻole ka hoʻoulu ʻana. ʻO ka laulā ana ʻo HRC20~67.
3. Vickers paʻakikī: hoʻohana ʻia e ana i ka paʻakikī o nā ʻāpana lahilahi a me nā ʻāpana pā kila, a hiki ke hoʻohana ʻia e ana i ka paʻakikī o nā ʻāpana paʻakikī o ka ʻili e like me ka carburizing, cyaniding, a me nitriding.
