Hlau daim duab tuag feem ntau yog xa mus rau ntau yam tuag siv rau kev kos duab hlau, nrog rau kev tuag rau kev kos duab fibers. Tag nrho cov hlau kos duab tuag muaj qhov nruab nrab ntawm ib qho duab tshwj xeeb- puag ncig, square, octagonal, lossis lwm cov duab tshwj xeeb. Raws li cov hlau tau kos los ntawm lub qhov tuag, nws qhov loj me yuav txo qis, thiab txawm tias nws cov duab yuav hloov. Rau kev kos cov hlau mos (xws li kub thiab nyiaj), steel tuag txaus; steel tuag tuaj yeem muaj ntau qhov ntawm qhov sib txawv.
Lub tshuab nqus hlau tuag yog ib hom pwm siv los ua cov hlau hlau. Nws lub hom phiaj tseem ceeb yog ncab thiab deform cov ntaub ntawv hlau, txo lawv txoj kab uas hla thiab ua kom lawv ntev kom tau txais cov xov hlau ntawm qhov xav tau tshwj xeeb. Lub luag haujlwm tseem ceeb ntawm kev kos duab tuag yog siv lub siab rau cov khoom siv hlau los ntawm lub qhov tsim sab hauv, ua rau cov yas deformation thaum nws dhau los ntawm lub qhov tuag, thaum kawg tsim cov hlau xav tau loj thiab qhov zoo. Hlau kos duab tuag tau dav siv hauv kev lag luam xws li xaim thiab cable, cov khoom siv hlau, cov khoom siv tsheb, cov cuab yeej tsim khoom, thiab cov khoom siv niaj hnub.
Hlau kos tuag feem ntau yog ua los ntawm cov hlau alloys los yog tungsten steel. Cov ntaub ntawv no muaj cov hardness siab, siab hnav tsis kam, thiab zoo toughness, ua rau lawv tiv taus lub siab thiab kev sib txhuam thaum lub sij hawm hlau stretching txheej txheem. Cov qauv tsim ntawm qhov tuag, xws li lub kaum sab xis compression (feem ntau yog 16-18 degrees), muaj kev cuam tshuam loj rau kev ua haujlwm ntawm cov txheej txheem kos duab thiab qhov zoo ntawm cov hlau. Kev xaiv ntawm lub kaum sab xis compression yuav tsum tau kho raws li cov khoom ntawm cov khoom siv hlau thiab lub hom phiaj hlau txoj kab uas hla. Lub kaum sab xis loj heev yuav ua rau lub zog tensile, thaum lub kaum sab xis me me yuav ua rau txo qis ntawm qhov zoo ntawm cov hlau.
Cov txheej txheem machining rau hlau kos tuag muaj xws li hlau txiav, precision sib tsoo, thiab npaj. Cov txheej txheem no ua kom lub siab precision thiab nto tiav ntawm qhov tuag, yog li lav qhov tseeb qhov tseeb thiab qhov zoo ntawm cov hlau.
