Cemented carbideine kuoma kwakanyanya, kazhinji pakati peHRA80 neHRA95 (Rockwell kuoma A).Izvi zvinodaro nekuti imwe chikamu checobalt, nickel, tungsten uye zvimwe zvinhu zvinowedzerwa kune simende carbide, izvo zvinoita kuti ive yakanyanya kupfeka kuramba uye kuoma.Iwo makuru akaomesesa nhanho mune simende carbide ndeye tungsten carbide (WC) uye tungsten carbide cobalt (WC-Co), pakati payo kuoma kweWC kwakakwira zvakanyanya, kunyange kuoma kupfuura diamond.Iyo cobalt muWC-Co zvinhu inogona kuwedzera kuomarara uye kushora kuramba kwezvinhu.Izvo zvinofanirwa kucherechedzwa kuti kuomarara kwecemented carbide kwakabatana nemakemikari ayo, nzira yekugadzirira, block density nezvimwe zvinhu, uye kuoma kwemhando dzakasiyana dzesimende carbide inogona kunge yakasiyana.
Cemented carbide ine kuomarara kwakanyanya uye kupfeka kuramba, uye inowanzoshandiswa kucheka zvinhu uye kugadzira maturusi.Asi hazvisi zvinhu zvese zvinogona kutemwa nyore kana kugadziriswa ne carbide, uye pane zvimwe zvisingakwanisi.Semuenzaniso, kucheka kuita kwecarbide zvishandisozvinogona kusiyana pakucheka mhando dzakasiyana dzesimbi.
Paunenge uchicheka simbi dzakaomarara, maturusi ecarbide anowanzoda machira akasarudzika kana magadzirirwo ejometri kuti varambe vachiita basa rekucheka.Panguva imwecheteyo, maturusi e-carbide akasimirirwa haakwanise kucheka zvinhu zvisingaite, segirazi uye ceramics.Naizvozvo, simende carbide haina zvachose pasina miganhu.Inoda kushandiswa mune chaiyo application mamiriro uye inoda kuvandudzwa musanganiswa nezvimwe zvinhu kana nzira dzekugadzira.
