txhuas tooj dag
Lead yog insoluble nyob rau hauv tooj dag thiab muab faib rau ntawm grain ciam nyob rau hauv lub xeev ntawm dawb hais. Lead tooj dag muaj ob hom: thiab (ntxiv rau) raws li nws lub koom haum. Alpha txhuas tooj dag tsuas tuaj yeem txias -deformed lossis kub-extruded vim muaj kev phom sij ntawm cov hlau lead thiab qis siab - kub plasticity. (ntxiv) txhuas tooj dag muaj cov yas zoo ntawm qhov kub thiab txias thiab tuaj yeem ua rau forged.
Tin tooj dag
The addition of tin to brass can significantly improve the heat resistance of the alloy, especially the ability to resist seawater corrosion, so tin brass is called "navy brass".
Tin tuaj yeem yaj mus rau hauv tooj liab{{0}}raws li kev daws teeb meem thiab ua lub luag haujlwm hauv 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 nyob rau hauv cov hlau, uas tsis haum rau cov yas deformation ntawm cov hlau. Yog li ntawd, cov ntsiab lus tin ntawm tooj dag yog feem ntau nyob rau hauv thaj tsam ntawm 0.5 feem pua rau 1.5 feem pua.
Feem ntau siv cov 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 kev txias thiab kub siab. Cov alloys ntawm ob qib tom qab muaj ib (ntxiv) ob-theem qauv, thiab ib qho me me ntawm r-theem feem ntau tshwm. Lub chav tsev kub plasticity tsis siab, thiab lawv tsuas yog deformed nyob rau hauv ib tug kub lub xeev.
Manganese tooj dag
Manganese muaj ntau dua solubility hauv cov tooj dag. Ntxiv 1 feem pua mus rau 4 feem pua ntawm manganese rau tooj dag tuaj yeem txhim kho lub zog thiab corrosion kuj ntawm cov hlau tsis txo nws cov yas.
Manganese brass has a ( plus ) structure, and HMn58-2 is commonly used. The pressure processing performance in cold and hot states is quite good.
