Tooj liab (Cu) General Information:

Nws yog xim liab-txiv kab ntxwv nyob rau hauv cov xim nrog lub melting point ntawm 1,083 ° C, ib tug ceev ntawm 8.92 g / cc, thiab ib tug vapor siab ntawm 10-4 Torr ntawm 1,017 ° C.

Raws li cov ntsiab lus ntawm cov pa oxygen thiab cov ntsiab lus impurity, oxygen-dawb tooj liab tau muab faib ua No. 1 thiab No. 2 oxygen-free copper. Lub purity ntawm No. 1 oxygen-dawb tooj liab ncav cuag 99.97%, cov ntsiab lus oxygen tsis ntau tshaj 0.003%, thiab tag nrho cov ntsiab lus impurity tsis ntau tshaj 0.03%; purity ntawm No. 2 oxygen-dawb tooj liab mus txog 99.95%, cov ntsiab lus oxygen tsis ntau tshaj 0.005%, thiab tag nrho cov ntsiab lus impurity tsis ntau tshaj 0.05%.

Oxygen-dawb tooj liab tsis muaj hydrogen embrittlement, siab hluav taws xob conductivity, kev ua tau zoo, vuam kev ua tau zoo, corrosion kuj thiab tsis kub kev kawm. Cov qauv rau cov ntsiab lus ntawm cov pa oxygen hauv ntau lub tebchaws tsis zoo ib yam, thiab muaj qee qhov sib txawv.

OFC (oxygen-dawb tooj liab): nws yog xim hlau tooj liab nrog purity ntawm 99.995%. Feem ntau siv hauv cov khoom siv hluav taws xob thiab hluav taws xob xws li cov khoom siv suab, lub tshuab nqus tsev hluav taws xob, cov cables, thiab lwm yam. Ntawm lawv, muaj LC-OFC (linear crystallized oxygen-dawb tooj liab lossis crystalline oxygen-dawb tooj liab): qhov purity siab dua 99.995% thiab OCC (ib leeg siv lead ua oxygen-dawb tooj liab): qhov siab tshaj plaws purity, siab tshaj 99.996%, thiab muab faib ua PC -OCC thiab UP-OCC thiab lwm yam.

Ib leeg siv lead ua oxygen-dawb tooj liab tsim siv UP-OCC thev naus laus zis (Ultra Pure Copper los ntawm Ohno Nruam Casting Txheej Txheem) tsis muaj kev taw qhia, siab purity, corrosion resistance, thiab tsis tshua muaj hluav taws xob impedance, ua rau cov hlau haum rau high-speed thiab high-zoo. teeb liab kis tau tus mob.

Copper (Cu) Hlau Element Txheej txheem cej luam:

Peb smelts ib yam ntawm cov hlau thiab feem ntau lwm cov ntaub ntawv siab heev rau hauv pas nrig, bar los yog phaj daim ntawv, los yog cov neeg muas zaub muab cov khoom kos duab.
Peb muag cov khoom sib txawv ntawm cov khoom siv tooj liab emetal los ntawm cov khoom hnyav lossis ib thooj rau kev siv sib txawv hauv cheeb tsam tshawb fawb thiab rau cov cuab yeej tshiab.

Piv txwv li: tooj liab hlau, tooj liab bar, tooj liab qws, tooj liab phaj, tooj liab ntawv, tooj liab raj, tooj liab yeeb nkab, tooj liab ntawv ci, tooj liab ingot, tooj liab pob, tooj liab pellets, tooj liab phiaj, tooj liab Crucible, tooj liab backing phaj, tooj liab raj. Lwm cov duab muaj nyob ntawm kev thov.
