(1) Kuoma kwepamusoro, kupfeka kuramba uye tsvuku-kuoma
Cemented carbide kuomarara pakamuri tembiricha inogona kusvika 86 ~ 93HRA, yakaenzana ne69 ~ 81HRC.mu900 ~ 1000 ℃ inogona kuchengetedza yakanyanya kuoma, uye yakanakisa kupfeka kuramba.Kuenzaniswa nesimbi yepamusoro-yekumhanya simbi, kumhanya kwekucheka kunogona kuva 4 kusvika 7 nguva yakakwirira, hupenyu 5 kusvika 80 nguva yakareba, inogona kucheka zvinhu zvakaoma nekuoma kusvika ku50HRC.
(2) Simba, yakakwirira modulus ye elasticity
Simba rekumanikidza resimende carbide inosvika 6000MPa, elastic modulus ye (4 ~ 7) × 105MPa, yakakwirira kudarika simbi inomhanya.Nekudaro, simba rayo rekuchinjika rakaderera, kazhinji 1000 kusvika 3000 MPa.
(3) Corrosion kuramba, oxidation kuramba kwakanaka
Kazhinji, kuramba kwakanaka kune corrosion yemhepo, asidhi, alkali, nezvimwe, hazvisi nyore kune oxidation.
(4) Diki coefficient of linear kuwedzera
Chimiro chakagadzikana uye saizi kana uchishanda.
(5) Zvigadzirwa zvakaumbwa hazvichagadziriswi uye kurodzwazve
Nekuda kwekuoma kwakanyanya uye brittleness yecemented carbide, hapasisina kucheka kana kugaya mushure meupfu metallurgy kugadzira uye sintering, uye pazvinenge zvichidikanwa kugadzirisazve, machining emagetsi akadai seEDM, kucheka waya, kugaya electrolytic kana vhiri rekukuya rinogona kushandiswa. .Kazhinji imwe dhizaini yezvigadzirwa zvakagadzirwa necemented carbide inosungirirwa, yakasungirirwa kana kusungirirwa pamagetsi pamutumbi wemidziyo kana mold yakanangana nekushandiswa.
