Cov Khoom Tseem Ceeb Ntawm Tungsten Alloy Phaj

Kev ua tau zoo ntawm tungsten alloy phaj yog ze rau lawv cov khoom tsim khoom. Hauv qab no yog qee yam khoom ntawm tungsten alloys rau siv.
High ceev: Qhov ceev ntawm tungsten alloy feem ntau yog 16.5-19.0g / cm3, uas yog sib npaug rau ntau tshaj ob npaug ntawm cov hlau.
Lub zog tensile siab: Lub zog tensile ntawm sintered W-Ni-Fe high-density alloy yog 800 ~ 1000MPa, thiab nws lub zog tuaj yeem nce mus rau 1300 ~ 1500 MPa tom qab kev kho cua sov thiab deformation ua.
Zoo ductility: W-Ni-Fe high-density alloy muaj ductility zoo heev, thiab nws sintered elongation tuaj yeem ncav cuag 10% ~ 15%. Tom qab lub tshuab nqus tsev lossis cua dehydrogenation kho, qhov elongation tuaj yeem nce mus rau 20% ~ 30%.
Kev muaj peev xwm zoo nqus hluav taws xob: kev ua kom siab ntom ntom ntom ntom nti muaj 30% rau 40% ntau dua lub peev xwm los nqus hluav taws xob ntau dua li kev coj ua.
Kev ua haujlwm hluav taws xob zoo: W-Ni-Cu thiab W-Ni-Fe high-density alloys muaj cov khoom siv hluav taws xob zoo, tiv thaiv corrosion, siab voltage, thiab lwm yam khoom siv hluav taws xob.
Zoo thermal conductivity thiab qis coefficient ntawm linear expansion: Nws thermal conductivity yog 5 npaug ntawm pwm hlau, thiab nws coefficient ntawm linear expansion tsuas yog 1/2 ~ 1/3 ntawm hlau los yog hlau.
Zoo corrosion kuj thiab oxidation kuj.
Cov yam ntxwv zoo machining: Vim qhov zoo tshaj plaws ductility ntawm W-Ni-Fe high-density alloys, lawv tuaj yeem ua rau tig, milling, npaj, threading, thiab tapping, nrog rau cov kev kho mob loj deformation xws li dov, swaging. , thiab forging.
