Phosphor Bronze Alloy thiab tooj dag yog ob chav kawm dav ntawm tooj liab alloys. Qhov sib txawv yog nyob ntawm cov khoom sib txawv thiab kev siv cov khoom xyaw.
Brass: Brass yog ib qho alloy uas muaj tooj liab thiab zinc. Yog tias nws tsuas yog tsim los ntawm tooj liab thiab zinc, nws yog hu ua tooj dag zoo tib yam. Yog tias muaj ntau yam alloys uas muaj ntau tshaj ob lub ntsiab lus hu ua tooj dag tshwj xeeb. Xws li tooj liab alloy muaj cov hlau lead, tin, manganese, nickel, lead, hlau, silicon. Brass muaj zog hnav tsis kam.
1. Cov muaj pes tsawg leeg yog txawv:
Brass yog ib qho alloy uas muaj tooj liab thiab zinc. Brass yog muab faib ua tooj dag zoo tib yam thiab tooj dag tshwj xeeb. Yog tias nws tsuas yog tsim los ntawm tooj liab thiab zinc, nws yog hu ua tooj dag zoo tib yam.
Yog tias muaj ntau yam alloys uas muaj ntau tshaj ob lub ntsiab lus hu ua tooj dag tshwj xeeb, tooj dag tshwj xeeb kuj hu ua tooj dag tshwj xeeb. Nws muaj lub zog siab, siab hardness, muaj zog tshuaj corrosion kuj, thiab zoo heev mechanical zog rau txiav.
Phosphor bronze, tseem hu ua bronze, yog tooj liab-tin alloy. Ntxiv 3-5 feem pua tin thiab 0.03-0.3 phosphorus rau tooj liab tuaj yeem txhim kho lub zog thiab tawv ntawm tooj liab.
2. Cov xim sib txawv:
Brass yog golden daj, phosphor bronze yog xim av, beryllium tooj liab yog phantom dawb, thiab tooj liab yog me ntsis ntshav.
3. Txawv hardness:
Phosphor bronze muaj zoo elasticity thiab muaj zog hardness, tooj dag muaj zoo toughness, thiab tshwj xeeb tooj dag. Nws muaj lub zog siab, siab hardness, muaj zog tshuaj corrosion kuj, thiab zoo heev mechanical zog rau txiav.
4. Kev siv sib txawv:
(1) Lub seamless tooj liab raj kos los ntawm tooj dag yog mos thiab hnav-resistant. Brass seamless raj tuaj yeem siv rau hauv cov khoom siv hluav taws xob thiab cov condensers, cov kav dej cryogenic, cov kav dej hauv hiav txwv. Kev tsim cov nplooj ntawv, tuav, rods, kav, casting qhov chaw, thiab lwm yam. Muaj 62 feem pua rau 68 feem pua tooj liab, nws muaj zog plasticity thiab tuaj yeem siv los tsim cov khoom siv siab.
Hauv kev lag luam thiab kev siv pej xeem, cov ntaub ntawv sib txawv raug xaiv raws li kev siv sib txawv. Yog tias nws yog ua los ntawm cov xov hlau, nws yuav tsum tau softer, yog li siv tooj liab. Yog tias nws siv los ua ib qho txuas, tooj dag feem ntau siv rau cov ntsia hlau. Feem ntau cov tooj dag muaj xim zoo, ua tau zoo, thiab ductility, thiab yooj yim rau electroplate lossis xim.
