1) Zoo heev hardness thiab hnav tsis kam Nyob rau hauv chav tsev kub, lub hardness ntawmcemented carbidetuaj yeem ncav cuag 8693HRA, uas yog sib npaug rau 6981HRC.Nws muaj lub siab tawv ntawm 900-1000 ° C thiab hnav tsis kam.Kev txiav ceev tuaj yeem ua tau 4-7 zaug sai dua li cov cuab yeej siv ceev ceev, lub neej kev pabcuam tuaj yeem txuas ntxiv los ntawm 5-80 zaug, thiab nws tuaj yeem txiav cov ntaub ntawv nyuaj nrog hardness txog 50HRC.2) Lub zog siab, siab elasticity Lub zog compressive ntawm cemented carbide yog siab li 6000MPa, thiab cov modulus ntawm elasticity yog (4-7) × 105MPa, uas yog ntau dua li ntawm high-speed steel.Txawm li cas los xij, nws lub zog flexural yog nruab nrab, xws li ntawm 1000 txog 3000 MPa.3) Zoo heev corrosion kuj thiab oxidation kuj Resistant rau huab cua, acid, alkali thiab lwm yam corrosion, tsis yooj yim rau oxidize.4) Tsawg coefficient ntawm linear expansion Thaum lub sijhawm ua haujlwm, cov duab thiab qhov loj nyob ruaj khov.5) Tsis muaj kev ua haujlwm ntxiv lossis regrinding ntawm cov khoom molded.Vim lub siab heev hardness thiab brittleness ntawmcemented carbide, nws tsis tuaj yeem txiav los yog rov ua dua tom qab hmoov metallurgy sib sau thiab sintering.Thaum rework yog tsim nyog kiag li, tsuas yog hluav taws xob machining, hlau txiav, electrolytic sib tsoo, thiab lwm yam los yog tshwj xeeb sib tsoo log sib tsoo yuav siv tau.Dimensions, feem ntau yog ua los ntawm cemented carbide, yog brazed, glued, los yog mechanically clamped rau lub cev cuab yeej los yog tuag.
