Tungsten screws feem ntau yog 50-200 npaug ntau kim dua li cov hlau stainless zoo tib yam. Qhov no feem ntau yog vim muaj kev sib xyaw ntawm plaub yam: cov khoom siv tsis txaus, cov txheej txheem tsim khoom nyuaj, kev xav tau tsis zoo, thiab cov nqi thev naus laus zis.
1. Raw Material Situation: Strategic Resource Scarcity and High nqi
Kev Pabcuam Nyiaj Txiag Txwv: Tungsten yog lub ntiaj teb tsis tshua muaj tswv yim hlau. Tuam Tshoj tuav 52% ntawm lub ntiaj teb reserves thiab 83% ntawm lub ntiaj teb no ntau lawm, tab sis tag nrho cov mining ntim yog tswj. Mining quotas tau nruj nyob rau hauv 2026, thiab me me thiab nruab nrab- mines me me raug yuam kom kaw vim ib puag ncig thiab kev nyab xeeb cov cai, ua rau muaj kev sib txuas ntxiv hauv cov khoom siv tau zoo.
Kev nce nqi ntawm cov khoom siv raw: Lub Ob Hlis 2026, tus nqi ntawm 55% dub tungsten concentrate yog 730,000 yuan / tus qauv ton, thiab ammonium paratungstate (national standard grade 0) yog 1.07 lab yuan / ton, sawv cev qhov nce ntxiv rau xyoo dhau los. Tsis tas li ntawd, tungsten raw cov ntaub ntawv suav txog 60% -70% ntawm cov nqi khoom, ncaj qha tsav cov nqi pib.
Ntiaj teb no Supply thiab Demand Imbalance: Lub ntiaj teb no tungsten mov-xav tau qhov sib txawv yog npaj yuav nthuav mus rau 19,200 tons ib xyoos twg los ntawm 2026 txog 2028, accounting rau ntau tshaj 17% ntawm tag nrho cov khoom. Kev thov tawg los ntawm cov khoom lag luam tshiab xws li photovoltaics thiab semiconductors (nrog rau photovoltaic tungsten hlau nkag mus rau ntau tshaj 80%) yuav ua rau cov khoom lag luam hnyav dua -xav tsis txaus.
2. Kev Ua Haujlwm Kawg: Kev ua haujlwm siab, kev poob siab, thiab kev siv zog
Cov txheej txheem sib sau ua ke: Yuav tsum tau muaj ntau cov kauj ruam, suav nrog hmoov metallurgy (isostatic nias), siab -kub sintering (2200-2400 degree), precision txiav, thiab xov dov. Nanocomposite tungsten screws kuj yuav tsum tau txhua yam alloying + tso plasma sintering. 3D luam ntawv ntawm qhov tsis xwm yeem zoo li yuav tsum tau siv tshuab electron beam melting, uas ua rau cov cuab yeej siv nyiaj txiag siab.
Strict Precision Control: Cov ntsia hlau me me yuav tsum tau xov precision ntawm ISO 3g-6g qib thiab nto roughness Ra tsawg dua lossis sib npaug li 0.1μm. Kev tshuaj xyuas lub zeem muag yog qhov tsim nyog los tshem tawm qhov tsis xws luag, nce tus nqi dhau los ntawm 90% mus rau ntau dua 98%. Qhov kev poob qis yog 3 npaug ntau dua li cov ntsia hlau zoo tib yam.
Kev siv hluav taws xob thiab nqi ib puag ncig: Cov txheej txheem sintering ib txwm muaj zog heev - siv zog. Txawm tias muaj kev ua kom zoo dua qub thiab kev txais yuav tsawg-kub sintering (2000 degree), kev siv hluav taws xob tseem yog tsib npaug ntawm kev ua hlau zoo tib yam. Kev kho ib puag ncig yuav tsum tau txhawb nqa cov khoom siv khib nyiab pov tseg thiab dej khib nyiab, ntxiv cov nqi tsim khoom ntxiv.
3. Technology Sab: Siab R & D Kev nqis peev, Qhov tseem ceeb Customization hwm
Core Technology Breakthrough Nqis: Txhawm rau hais txog chav tsev- qhov kub thiab txias ntawm tungsten, kev tshawb fawb thiab kev txhim kho ntawm nanocomposite ntxiv dag zog rau cov cuab yeej siv thiab cov txheej txheem txheej txheej txheej txheej txheej txheej, nrog ib zaug - project R&D kev nqis peev ntau tshaj kaum lab yuan. 3D luam ntawv ntawm irregularly zoo li tus screws yuav tsum tau structural structural sib txawv. 3 lub hlis mus rau 2 lub lis piam, tab sis thawj cov cuab yeej siv thiab cov cuab yeej cuab tam raug nqi.
Customization Adaptation Nqis: Cov teb sib txawv muaj ntau qhov kev ua tau zoo sib txawv rau tungsten screws (piv txwv li, tsis yog- sib nqus + biocompatible rau kev kho mob, siab- kub + kev co- tiv taus rau kev siv aerospace), yuav tsum tau hloov kho rau cov qauv alloy (tungsten-}} tooj liab tungsten-rhenium, thiab lwm yam) thiab cov qauv xov (tus kheej-aligning, hollow channels). Cov me me-batch customization ua rau cov nqi tsev siab tsis tu ncua.
4. Sab Hauv Kev Ua Lag Luam: Tight Supply-Xav tau qhov nyiaj tshuav, Cov nqi hloov pauv siab heev
Tsis muaj lwm yam khoom siv zoo: Hauv qhov chaw huab cua xws li kub siab tshaj 2000 degree, muaj zog hluav taws xob, thiab muaj zog corrosion, tungsten lub melting point (3422 degree) thiab ntom (19.3g / cm³) yog irreplaceable. Downstream siab- cov tuam txhab tsim khoom kawg txaus siab them tus nqi kom ntseeg tau cov khoom lag luam.
Tsis muaj zog Bargaining Power nyob rau hauv Supply Chain: tungsten cov kev pab cuam yog concentrated nyob rau hauv ob peb lub tuam txhab, ua rau muaj teeb meem rau downstream processing tuam txhab uas muag nyob rau hauv tau txais tungsten thiab ib tug teeb meem ntawm "teeb meem ntawm kev nrhiav thiab kev tsov kev rog rau cov nqi siab dua." Tsis tas li ntawd, cov txheej txheem tungsten rov ua dua tseem tsis tau paub meej, nrog rau tam sim no tus nqi rov qab tsuas yog nyob ib ncig ntawm 98%, ua rau nws nyuaj rau kev txo qis kev vam khom ntawm thawj tungsten hauv lub sijhawm luv.
