Cov hlau lead
Lead yog xyaum insoluble nyob rau hauv tooj dag, thiab faib rau grain ciam teb nyob rau hauv daim ntawv ntawm dawb hais. Lead tooj dag tuaj yeem muab faib ua thiab (ntxiv rau) raws li nws cov qauv. Alpha txhuas tooj dag tuaj yeem tsuas yog txias deformed lossis kub extruded vim muaj kev phom sij ntawm cov hlau lead thiab tsis tshua muaj plasticity ntawm qhov kub thiab txias. (ntxiv) txhuas tooj dag muaj cov yas zoo ntawm qhov kub thiab txias thiab tuaj yeem ua rau forged.
tooj dag
Adding tin to brass can obviously improve the heat resistance of alloy, especially the ability of resisting seawater corrosion, so tin brass is called "navy brass".
Tin tuaj yeem yaj hauv tooj liab {{{0}}}raws li cov kuab tshuaj, uas ua lub luag haujlwm ntawm kev ua kom muaj zog ntxiv. Txawm li cas los xij, nrog kev nce ntawm cov ntsiab lus tin, brittle R theem (CuZnSn compound) yuav tshwm sim hauv cov hlau, uas tsis tsim nyog rau cov yas deformation ntawm cov hlau, yog li cov ntsiab lus tin ntawm tooj dag feem ntau nyob rau hauv thaj tsam ntawm 0.5 feem pua 1.5. feem pua.
Feem ntau siv tin tooj dag yog HSn70-1, HSn62-1, HSn60-1, thiab lwm yam. Cov qub yog alpha alloy, uas muaj cov yas siab thiab tuaj yeem ua tiav los ntawm txias thiab kub nias. Cov alloys ntawm ob qib tom qab muaj (ntxiv rau) ob-theem qauv, thiab ib qho me me ntawm R theem feem ntau tshwm. Lawv plasticity ntawm chav tsev kub tsis siab, thiab lawv tsuas tuaj yeem deform hauv lub xeev kub.
manganese tooj dag
Manganese muaj solubility zoo hauv cov tooj dag. Ntxiv 1 feem pua 4 feem pua ntawm manganese rau tooj dag tuaj yeem txhim kho lub zog thiab corrosion tsis kam ntawm cov hlau tsis txo nws cov yas.
Manganese tooj dag muaj (ntxiv rau) qauv, HMn58-2 feem ntau yog siv, thiab nws cov xovxwm ua haujlwm hauv lub xeev txias thiab kub yog qhov zoo heev.
