Lub ntsiab hom tooj dag

tooj dagyog ib qho alloy ntawm tooj liab thiab zinc, nrog cov xim daj zoo nkauj, suav nrog lub npe tooj dag. Raws li nws cov tshuaj muaj pes tsawg leeg, tooj dag muab faib ua tooj liab zoo tib yam thiab tooj dag tshwj xeeb.
Ordinary tooj dag yog binary alloy ntawm tooj liab thiab zinc. Vim nws cov yas zoo, nws yog qhov tsim nyog rau kev tsim cov phaj, tuav, xov hlau, cov raj thiab cov khoom sib sib zog nqus, xws li condensers, cov kav dej kub, electro-mechanical qhov chaw, thiab lwm yam. Brass alloys nrog cov ntsiab lus tooj liab nruab nrab ntawm 62% thiab 59% kuj tuaj yeem raug cam khwb cia, uas yog hu ua tooj dag.
Cov tooj dag tshwj xeeb yog hlau-raws li alloy. Txhawm rau kom tau txais lub zog siab dua, kev tiv thaiv corrosion thiab kev ua haujlwm zoo, aluminium, silicon, manganese, txhuas, tin thiab lwm yam hlau raug ntxiv rau cov tooj liab-zinc alloy los tsim cov tooj dag tshwj xeeb. Xws li txhuas tooj dag, tooj dag, txhuas tooj dag, tooj dag silicon, manganese tooj dag, thiab lwm yam
Cov hauv qab no yog qee qhov tshwj xeeb tooj dag.
Cov hlau lead
Lead tooj dag yog ib qho ntawm cov khoom siv tshwj xeeb tshaj plaws, nrog rau kev ua haujlwm zoo thiab hnav tsis kam. Cov ntsiab lus ntawm cov hlau lead yog tsawg dua 3%, thiab feem ntau ntawm Fe, Ni los yog Sn yog ntxiv.
Tin tooj dag
Tin tooj dag yog tooj dag nrog tin plated ntawm tooj liab-zinc alloy. Ib qho tshwj xeeb tooj dag uas muaj li ntawm 1% tin. Ntxiv ib qho me me ntawm cov tin tuaj yeem ua kom lub zog thiab hardness ntawm tooj dag, tiv thaiv dezincification, thiab txhim kho corrosion kuj ntawm tooj dag.
Silicon tooj liab
Silicon hauv silicon tooj dag tuaj yeem txhim kho cov khoom siv kho tshuab, hnav tsis kam thiab corrosion kuj ntawm tooj liab. Silicon tooj dag yog tsuas yog siv los tsim cov khoom hauv hiav txwv thiab cov khoom siv tshuaj lom neeg.
Manganese tooj dag
Manganese tooj liab yog cov hlau tsis kam nrog tooj liab thiab manganese ua cov khoom tseem ceeb. Nws tsim cov qauv resistors, shunts thiab cov ntsiab lus tsis kam nyob rau hauv cov twj paj nruag thiab meters.
