Hom ntawm High Copper Alloys
High tooj liab alloy yog ib lo lus dav dav rau alloys nrog ntau dua Cu cov ntsiab lus ntawm lwm cov tooj liab alloys. Nws yog ib pawg ntawm cov alloys uas tsuas yog txhim kho cov khoom siv kho tshuab thiab ua kom sov. Cov ntsiab lus tooj liab feem ntau yog nyob nruab nrab ntawm 99.3% thiab 96%, tab sis nws tsis tuaj yeem muab faib ua lwm hom tooj liab alloy. High tooj liab alloy muaj hluav taws xob zoo thiab thermal conductivity, thiab muaj cov yam ntxwv ntawm corrosion kuj, nruab nrab lub zog, thiab yooj yim ua thiab tsim. Nws kuj muaj qhov kub zoo softening peev xwm, yog li nws yog dav siv nyob rau hauv automotive dej tso tsheb hlau luam, tshav kub dab dej, lub cev muaj zog commutators, relays thiab lwm yam teb. Ntxiv nrog rau cov yam ntxwv no, tooj liab tsis cuam tshuam rau nws cov txheej txheem thiab kev ua haujlwm, uas yog qhov zoo tshaj plaws ntawm tooj liab, yog li nws tuaj yeem hais tias yog cov khoom siv sib npaug ntawm ob. Muaj ntau lub npe tom qab ntxiv cov ntsiab lus, xws li beryllium tooj liab, titanium tooj liab, silver-muaj tooj liab, tin-muaj tooj liab, chromium tooj liab, zirconium tooj liab, tooj liab-hlau alloy, Corson tooj liab-kub, thiab lwm yam.
Beryllium tooj liab
Nws yog ib tug nag lossis daus hardening tooj liab alloy. Raws li lub npe qhia, Be (berylium) yog ntxiv los ua kom nws lub zog. Nws yog Cu-Be-Co (cobalt) raws li alloy. Nws yog cov khoom muaj zog tshaj plaws ntawm cov tooj liab alloys, thiab muaj ntau hom raws li kev faib ua feem ntawm Be. Ntxiv nrog rau lub zog tensile, nws kuj muaj lub siab elastic modulus, yog li nws yog standardized rau springs. Nws kuj yog siv los ua cov khoom pwm, vuam electrodes, precision machinery qhov chaw.
Titanium tooj liab
Cu-Ti raws li tooj liab alloy, tseem hu ua hnub nyoog-hardening alloy. Nws lub zog thiab kub tsis kam yog piv rau beryllium tooj liab, tab sis nws cov hluav taws xob conductivity tsis zoo. Nws tseem yog lub npe hu rau nws lub caij nplooj ntoos hlav siab txwv. Txawm hais tias lub zog tensile tshaj 1000N / mm2, qhov hluav taws xob conductivity tsawg dua 20% IACS.
Corson alloy
Copper alloy nrog Cu-Ni-Si raws li cov matrix kuj tseem siv tau los ua cov khoom siv caij nplooj ntoos hlav vim nws qhov siab elastic txwv, kev co kuj, qaug zog thiab lwm yam ntxwv. Nws yog lub hnub nyoog-hardening alloy nrog Ni 2 Si raws li nag lossis daus theem, thiab yog cov khoom siv zoo tensile zog thiab hardness.
Tooj thiab nyiaj
Nws yog tooj liab alloy nrog nyiaj ntxiv. Los ntawm kev ntxiv nyiaj, uas muaj hluav taws xob zoo dua thiab thermal conductivity dua tooj liab, peb saib xyuas kom tsis txhob txo cov khoom no ntau dhau. Qhov siab tshaj plaws ua haujlwm kub yog 300 degree. Cov tooj liab alloy nrog hluav taws xob conductivity thib ob tsuas yog tooj liab ntshiab.
Tinned tooj
Nws yog ib qho alloy raws li tin (Sn) thiab tooj liab, thiab nws cov conductivity txawv heev nyob ntawm seb cov tin ntxiv. Qhov siab tshaj plaws ua haujlwm kub yog 300 degree.
Chromium tooj liab
Qhov no yog tooj liab alloy nrog chromium ntxiv, uas txhim kho hnav tsis kam ntawm qhov kub thiab txias vim yog cov yam ntxwv ntawm chromium. Yog tias hardened ntawm 1000 degree thiab tom qab hnub nyoog ntawm 500 degree, qhov softening kub yog 500 degree.
Zirconium tooj liab
Copper alloy muaj zirconium. Txhim kho cov cua sov ua haujlwm, siv los ua cov khoom siv hluav taws xob kub-resistant. Ntxiv mus, ntawm cov tooj liab alloys, nws muaj conductivity zoo dua, qhia conductivity thib ob tsuas yog nyiaj-muaj tooj liab.
Tooj / hlau alloy
Ib qho hlau, phosphorus thiab tooj liab uas txhim kho lub zog los ntawm nag lossis daus hardening thiab ua haujlwm hardening. Nws yog cov khoom siv tiv thaiv corrosion thiab kev ntxhov siab corrosion cracking thiab tuaj yeem welded lossis brazed.
