Cemented carbide punch yog ib feem ntawm cemented carbide tuag, tseem hu ua cemented carbide punch lossis cemented carbide punch. Nws feem ntau yog siv rau xuas nrig ntaus qhov khoos phis tawj lossis khoom siv hluav taws xob, tau kawg, nws tseem tuaj yeem ntaus lwm yam tsis yog hlau. Tej daim, txawm tias siv qhov, yas qhov, thiab lwm yam. Cemented carbide, tseem hu ua tungsten steel, hais txog cov khoom siv sib xyaw ua ke uas muaj tsawg kawg ib lub hlau carbide. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, thiab tantalum carbide yog ib feem ntawm tungsten hlau. Qhov loj me me ntawm cov khoom siv carbide (lossis qib) feem ntau yog nruab nrab ntawm 0.2-10 microns, thiab cov carbide nplej tau sib koom ua ke siv cov ntawv hlau. Cov ntawv nplaum feem ntau hais txog cov hlau cobalt (Co), tab sis rau qee qhov kev thov tshwj xeeb, npib tsib xee (Ni), hlau (Fe), lossis lwm yam hlau thiab cov hlau phom kuj tseem tuaj yeem siv tau. Lub matrix ntawm cemented carbide yog tsim los ntawm ob ntu: ib feem yog theem tawv; lwm qhov yog cov hlau sib txuas. Cov hlau sib txuas feem ntau yog hlau pawg hlau, thiab cobalt thiab npib tsib xee feem ntau siv. Yog li muaj cov tungsten-cobalt alloys, tungsten-nickel alloys thiab tungsten-titanium-cobalt alloys
