Carbide extruded brass

1) Yakanakisa kuomarara uye kupfeka kuramba Pamhepo tembiricha, kuoma kwesimende carbideinogona kusvika 8693HRA, iyo yakaenzana ne6981HRC.Iine hurema hwepamusoro hwe900-1000 ° C uye yakanaka kupfeka kuramba.Iyo yekucheka kumhanya inogona 4-7 nguva nekukurumidza kupfuura yakakwirira-yekumhanyisa chishandiso simbi, hupenyu hwesevhisi hunogona kuwedzerwa ne5-80 nguva, uye inogona kucheka zvinhu zvakaomarara nekuoma kusvika ku50HRC.2) Kusimba kwepamusoro, kusimba kwepamusoro Simba rekumanikidza recemented carbide rinosvika 6000MPa, uye modulus ye elasticity ndeye (4-7) × 105MPa, iyo yakakura kudarika yesimbi inomhanya.Nekudaro, simba rayo rekuchinjika rine mwero, kubva pa1000 kusvika 3000 MPa.3) Yakanakisa corrosion resistance uye oxidation resistance Inopokana nemhepo, asidhi, alkali uye kumwe kusvibiswa, zvisiri nyore kuita oxidize.4) Low coefficient yekuwedzera kwemutsara Panguva yekushanda, chimiro uye ukuru zvinoramba zvakagadzikana.5) Hapana imwezve kugadzirisa kana kugaya zvinhu zvakaumbwa.Nekuda kwekuoma kwakanyanya uye brittleness yesimende carbide, haigone kutemwa kana kugadziridzwa mushure mehupfu hwesimbi kuumba nekunyungudutswa.Kana rework ichinyatsodikanwa, chete magetsi ekuburitsa machining, kucheka waya, electrolytic kugaya, nezvimwewo kana yakakosha kugaya vhiri kugaya inogona kushandiswa.Zviyero, zvinowanzo gadzirwa necemented carbide, zvinonamirwa, zvakanamirwa, kana kusungirirwa kumudziyo wemidziyo kana kufa.
