Beryllium tooj liab-tseem hu ua lub caij nplooj ntoos hlav tooj liab, BeCu, tooj liab beryllium, thiab beryllium bronze-yog tooj liab-raws li alloy uas muaj ntau yam ntawm beryllium. Cov ntsiab lus beryllium feem ntau nyob ntawm 0.4 mus rau 2%.
Raws li ib qho ntawm lub zog siab tshaj plaws tooj liab-raws li alloys, cov khoom siv no pom daim ntawv thov thoob plaws txhua qhov kev lag luam. Ntxiv nrog rau nws lub zog siab, qib sib txawv ntawm beryllium tooj liab kuj qhia tau lwm yam khoom tsim nyog rau ntau yam kev siv hauv kev lag luam, xws li kev ua tau zoo heev thiab tsis sib nqus.
Cov khoom ntawm Beryllium Copper
Beryllium tooj liab thiab nws ntau yam ntawm alloys nthuav tawm ntau yam khoom, suav nrog:
1. Muaj hluav taws xob thiab thermal conductivity
2. Cov yam ntxwv tsis muaj teeb meem thiab tsis sib nqus
3. High ductility thiab zoo heev formability hais txog kev tsim, machining, thiab metalworking txheej txheem
4. Kev tiv thaiv corrosion thiab oxidation ntau dua li cov hlau
5. Ntau dua durability dua li feem ntau tooj liab alloys (resists hnav thiab galling)
6. Khaws cov khoom nyob rau hauv qhov kub thiab txias heev
7. Haum rau kev ua haujlwm los nag-tawv tawv
8. Siab qaug zog-tseem hu ua endurance zog-ua rau nws haum rau hnyav cyclic load daim ntaub ntawv
Qib ntawm Beryllium Copper
Beryllium tooj liab muaj nyob rau hauv ntau qib sib txawv, txhua tus muaj nws tus kheej zoo. Cov qib no tau muab faib ua ob pawg loj:siab zog alloysthiabsiab conductivity alloys.
Piv txwv ntawm lub zog siab alloys muaj xws li:
1. Cov alloy no yog qib feem ntau ntawm beryllium tooj liab. Nws muaj 1.8 mus rau 2% beryllium thiab ua kom pom lub zog tensile li ntawm 60-220 kilopounds ib square inch (ksi) thiab qaug zog ntawm 30-50 ksi ib 10 ^ 8 cycles.
2. Cov hlau no kuj muaj 1.8 mus rau 2% beryllium. Nws pom zoo machinability, siab endurance, so tsis kam, thiab tus yam ntxwv lub zog-conductivity piv.
3. Cov hlau no muaj 1.6 txog 1.79% beryllium. Nws cov hluav taws xob conductivity feem pua feem ntau poob ntawm 15 mus rau 33% (ib International Annealed Copper Standard).
Qee qhov siab conductivity alloys suav nrog:
1. Cov hlau no muaj 0.2 rau 0.6% beryllium. Nws pom tau tias qhov hluav taws xob conductivity feem pua ntawm yam tsawg 60%.
2. Cov hlau no muaj 0.4 rau 0.7% beryllium. Nws lub zog tensile feem ntau poob ntawm 50-80 ksi.
3. Cov hlau no muaj qee qhov qis tshaj plaws ntawm beryllium ntawm ntau qib muaj, poob hauv thaj tsam ntawm 0.15 txog 0.5%. Nws muaj qhov qis elongation feem pua (7 txog 17%).
4. Cov hlau no yog tsim los ntawm Brush Wellman. Nws muaj nyob nruab nrab ntawm 0.15 mus rau 0.5% beryllium, muab khoom hardened, thiab ua kom pom tseeb tias muaj zog txhua yam thiab hluav taws xob conductivity.
Daim Ntawv Thov / Kev Lag Luam Ua Haujlwm los ntawm Beryllium Copper
Beryllium tooj liab pom siv hauv ntau qhov kev lag luam sib txawv vim nws cov khoom tshwj xeeb. Piv txwv li, nws cov yam ntxwv tsis ua rau nws tsim nyog rau cov ntawv thov hauv kev lag luam roj thiab roj, xws li cov roj rig Cheebtsam lossis cov cuab yeej mining.
Lwm daim ntawv thov kev lag luam uas siv beryllium tooj liab suav nrog:
1. Computers thiab electronics
2. Kev tsim cov cuab yeej uas tsis muaj teeb meem
3. Fasteners
4. Cov khoom siv sib txuas lus
5. Valve rooj zaum thiab cryogenics
6. Txhaj pwm tsim
7. Suab paj nruag (percussion, hlua, thiab lwm yam)
