Ib qho ntawm cov txheej txheem tseem ceeb hauv kev tsim tooj liab hlau yog kos duab. Kev kos duab suav nrog rub tus pas nrig tooj liab lossis billet los ntawm kev tuag los txo nws txoj kab uas hla thiab elongate rau hauv ib txoj hlua ntev, txuas ntxiv mus. Lub malleability ntawm tooj liab tso cai rau nws yooj yim kos rau hauv nyias strands yam tsis muaj kev tawg lossis tawg. Cov txheej txheem no tuaj yeem rov ua dua ntau zaus kom ua tiav qhov xav tau ntawm txoj kab uas hla, kom ntseeg tau tias cov khoom siv ntawm cov xov hlau muaj qhov ntev.
Tooj hlau kuj tseem tuaj yeem ua kom yooj yim annealed, txheej txheem uas muaj cua sov cov hlau thiab tom qab ntawd txias nws maj mam txo cov kev ntxhov siab sab hauv thiab txhim kho nws cov ductility. Annealing pab rov qab softness thiab saj zawg zog ntawm cov hlau, ua rau nws yooj yim dua mus ntxiv txheej txheem los yog manipulate. Cov cuab yeej no tshwj xeeb tshaj yog thaum cov hlau yuav tsum tau khoov, twisted, los yog tsim rau hauv cov duab complex thaum lub sij hawm installation los yog sib dhos.
Ntxiv nrog rau kev kos duab thiab annealing, tooj liab hlau tuaj yeem ua tiav los ntawm ntau yam kev ua haujlwm thib ob. Cov haujlwm no suav nrog kev txiav, stripping, tinning, thiab soldering, thiab lwm yam. Copper qhov zoo tshaj plaws conductivity thiab thermal zog tso cai rau kev ua tau zoo thiab txhim khu kev qha ntawm cov txheej txheem no.
Qhov yooj yim ntawm kev ua tooj liab txuas mus rau nws txoj kev sib raug zoo nrog lwm cov ntaub ntawv. Tooj tooj hlau tuaj yeem txuas tau yooj yim los yog txuas nrog lwm yam khoom, xws li cov khoom sib txuas, cov khoom siv hluav taws xob, lossis cov khoom siv hluav taws xob. Qhov no pab txhawb kev sib koom ua ke ntawm tooj liab hlau rau hauv cov khoom siv hluav taws xob thiab hluav taws xob, ua kom muaj kev sib raug zoo thiab txhim khu kev qha.
Tsis tas li ntawd, qhov versatility ntawm tooj liab txuas mus rau nws lub peev xwm los coated los yog plated nrog lwm yam ntaub ntawv. Coatings xws li tin, nyiaj, los yog npib tsib xee tuaj yeem siv los txhim kho cov hlau cov khoom lossis muab kev tiv thaiv ntxiv tiv thaiv corrosion. Cov txheej txheem no tuaj yeem siv tau yooj yim siv ntau yam electroplating lossis kub-dip txheej txheem, kom ntseeg tau tias muaj kev sib txuam thiab txhim khu kev qha.
Hauv cov ntsiab lus, tooj liab hlau qhov yooj yim ntawm kev ua haujlwm yog qhov txiaj ntsig zoo hauv ntau yam kev lag luam thiab kev siv. Nws cov ductility siab thiab malleability tso cai rau kev kos duab zoo, annealing, thiab lwm yam kev ua haujlwm, ua rau cov xov hlau uas muaj qhov ntev thiab cov khoom xav tau. Lub compatibility ntawm tooj liab hlau nrog rau lwm yam ntaub ntawv, raws li zoo raws li nws muaj peev xwm yuav coated los yog plated, ntxiv expands nws ntau yam ntawm daim ntaub ntawv. Cov yam ntxwv ua haujlwm no ua rau cov xov tooj tooj liab muaj ntau yam thiab txhim khu kev qha rau hluav taws xob, hluav taws xob, thiab tshuab tshuab.
