Tungsten Contact Point Rivet: Cov Khoom Siv Tsis Zoo, Kev Tswj Xyuas Tsis Zoo Thiab Hla -Kev Lag Luam Daim Ntawv Thov Kev Ntsuas

Tungsten Contact Point Rivets ua haujlwm ua hluav taws xob ua -cov khoom tawg rau kev sib cuag tawg, qis-voltage relays, thiab EV HVDC contactors, nrog ntau dua lossis sib npaug rau 99.95% tungsten purity xa cov arc ablation tsis kam 3-6 npaug siab dua cov tooj liab ntshiab rivets hauv qab 00 12V. Tus qauv rivet ceev ncav cuag 19.0 g / cm³, melting point tsau ntawm 3410 degree, uas tshem tawm kev sib cuag melting nyob rau hauv 3000-5000℃hloov arc kub thiab txiav kev sib cuag nto cov ntaub ntawv poob tus nqi los ntawm 72% piv rau unalloyed silver contacts nyob rau hauv cyclic lag luam. Tsab ntawv xov xwm no suav txog cov kev ntsuas cov khoom tseem ceeb, teev cov tsav tsheb tsis ua haujlwm rau kev sib dhos rivet, thiab txheeb xyuas cov ntawv thov raug txheeb xyuas rau OEM hluav taws xob tivthaiv tsim thiab QA validation.

Tag nrho cov ntaub ntawv xeem ua raws li ASTM B760 thiab GB / T 4188 cov qauv ntsuas cov khoom, ntsuas ntawm rivets tsim los ntawm cov hmoov metallurgy nias thiab 1500-2000℃nqus sintering txheej txheem.

Thermal khoom tsis tu ncua

• Melting point: 3410 degree; linear thermal expansion coefficient: 4.5 × 10⁻⁶ / K, 73% qis dua tooj liab 17 × 10⁻⁶ / K kom txo cov thermal stress cracking hauv rivet cuam tshuam haum cov qauv.
• Thermal conductivity: 160–180 W / (m·K), cov cua kub zoo sib xws tiv thaiv cov chaw hauv cheeb tsam ntawm Tungsten Rivets mating nto thaum lub sij hawm hloov mus tas li.

Cov ntsuas hluav taws xob ua haujlwm

• Hluav taws xob conductivity: 28-32% IACS; ruaj khov tiv thaiv tuav hauv qab 25 mΩ tom qab 100,000 ua - tawg voj voog nyob rau hauv 15A DC load.
• Arc withstand peev: Ib Pure Tungsten Hu rau cuam tshuam lub ncov ntu ntu tam sim no mus txog 45A yam tsis muaj vuam lossis qhov chaw ruaj khov.

Mechanical dimensional & hardness qauv

• Vickers hardness: 680 HV; tensile lub zog: 550-800 MPa, tiv taus txhua yam cuam tshuam los ntawm kev sib cuag lub caij nplooj ntoos hlav reciprocation.
• Standard Customized Flat Tungsten Contact Rivets dimensional kam rau ua: Lub taub hau txoj kab uas hla ± 0.1 hli, shank txoj kab uas hla ± 0.05 hli, shank ntev ± 0.15 hli; grain ceev tswj ntawm 10,000-20,000 grains ib mm² rau uniform nto abrasion kuj.

Oxidation stability

• Tsis pom oxide txheej tsim tom qab 200- teev qhov kub thiab txias ntawm 180 degree; nto oxidation kuj tshem tawm kev tiv thaiv drift hauv cav compartment high-temperature ib puag ncig.

Cov tsoos tooj liab thiab nyiaj rivets ua tsis tau sai nyob rau hauv siab - zaus hloov vim lawv qhov qis melting point thiab hnyav arc ablation. Tungsten Copper Contacts daws ob qhov tseem ceeb loj- hom kev ua haujlwm tsis ua haujlwm: kev sib cuag welding nyob rau hauv overload tam sim no thiab qhov sib txawv ntawm qhov sib txawv tshwm sim los ntawm cov khoom yaig.

Kev ua haujlwm ntawm cov khoom siv tau txiav txim siab txog thaj tsam ntawm kev siv tsheb, kev lag luam qis -voltage, thiab lub zog tshiab DC cov ntu ntu, nrog rau tag nrho cov khoom rivet RoHS thiab REACH raws li kev hla - ciam teb thauj khoom loj:

Mechanical contact breaker ignition systems (Internal combustion tsheb, maus taus)

Standard rivet specification: shank txoj kab uas hla 1.5-2.5 hli, tiaj puag ncig lub taub hau. Kev khiav hauj lwm ib puag ncig: -40℃txog 150 degree, cyclic switching zaus mus txog 120 Hz nyob rau hauv lub cav puv-ceev ua hauj lwm. High tungsten density restrains arc yaig kom stabilize ignition lub sij hawm sib xws.

Tsawg-tam sim no muaj relays & me me Circuit Court breakers

Tungsten Copper Button Contacts yog siv rau 5A-30A DC load switching, hloov nyiaj -cadmium composite hu kom tshem tawm cadmium hnyav hlau txaus ntshai. Cov qauv rivet txhawb nqa automated nruam riveting ntawm stamping ntau lawm kab, nrog sib dhos yield stabilized saum 99.98%.

EV siab -voltage DC contactor auxiliary switching sub- sib dhos

Ib nrab Hollow Tungsten Contact Rivets raug xa mus rau BMS teeb liab Circuit Court ua- tawg nyob rau hauv 400V-800V siab-voltage ib puag ncig. Tsawg thermal expansion coefficient sib tw tooj liab tiv thaiv caj npab thermal deformation nkhaus, zam kev sib dhos tsis ua haujlwm thaum lub sij hawm ntev - lub sij hawm them nqi tsheb - tawm mus.

Automotive hluav taws xob horn core hu

Siab - zaus reciprocating switching (txog 500 cycles ib feeb) generates sustained hluav taws xob arcs; Hluav taws xob Horn Tungsten Contacts txiav ntau zaus hloov los ntawm 70% piv rau tooj dag hu rau rivets hauv tsheb tom qab- muag cov txheeb cais muag.

Tungsten contact point rivets vam khom siab melting point, standardized sintered microstructure, thiab ruaj khov hluav taws xob conductivity los hais txog cov ntsiab lus tseem ceeb ntawm qhov mob ntawm cov tshuab hloov khoom siv. Rau pab pawg neeg muab khoom OEM, tus tsim qauv engineering, thiab QA cov kws tshaj lij, kev xaiv cov khoom yuav tsum kaw peb lub ntsiab lus qhia: tungsten purity Ntau dua lossis sib npaug li 99.95%, hu rau qhov chaw tiaj tus tsawg dua lossis sib npaug li 0.008 hli, thiab qhov ntev ntev ntawm qhov sib txawv ntawm lub hom phiaj sib dhos sib txawv. Standardized siab-purity rivet specifications txo cov ncej- lag luam tsis ua hauj lwm tus nqi ntawm breakers, relays, thiab EV DC contactors, txo tag nrho cov khoom lifecycle tu nqi rau cov khoom siv hluav taws xob.

Raws li cov kws tshaj lij kev lag luam tsom rau cov khoom siv hluav taws xob tiv tauj thiab cov hlau stamping precision, peb muaj cov hmoov metallurgy paub tab thiab lub tshuab nqus tsev sintering ntau lawm kab, txhawb customizedTungsten Contact Point Rivetspecifications rau OEM / ODM tsim yuav tsum. Peb lub Hoobkas nruj me ntsis ua raws li IATF 16949 kev tswj hwm kev ua haujlwm zoo, muab cov ntawv qhia tag nrho cov ntawv xeem thiab RoHS / REACH daim ntawv pov thawj rau txhua qhov khoom xa tuaj. Rau kev sim ceev ceev, cov lus txiav txim ntau, lossis kev txheeb xyuas qhov tseeb, thov hu rau peb pab pawg engineering ncaj qha.
