Brass Rods: Ntau yam tooj liab-Zinc khoom
Hauv tsev neeg ntawm cov ntaub ntawv hlau, tooj dag pas nrig, raws li tus neeg sawv cev ntawm tooj liab-zinc alloys, tau dhau los ua cov khoom siv tseem ceeb hauv kev tsim khoom nrog lawv cov kev ua tau zoo sib xws. Piv nrog cov tooj liab ntshiab, tooj dag ua tiav kev ua tau zoo hauv lub zog, hardness, thiab corrosion kuj los ntawm alloying nrog zinc, yoog mus rau ntau yam kev lag luam.
Sib npaug ntawm cov cuab yeej cuab tam
Lub zog tensile ntawm tooj dag pas nrig feem ntau yog nruab nrab ntawm 300 thiab 500 MPa nyob ntawm cov ntsiab lus zinc, ntau dua li ntawm 200 txog 300 MPa ntawm cov tooj liab ntshiab, thaum tuav cov yas zoo nrog elongation ntawm 15 mus rau 40 feem pua. Lub zog thiab plasticity ua ke ua ke ua rau tooj dag tuaj yeem tiv taus cov khoom hnyav xws li kev co thiab kev cuam tshuam thaum ua tiav cov duab los ntawm kev ua haujlwm txias xws li stamping thiab dabtsi yog khoov, lossis ua haujlwm kub xws li extrusion thiab casting. Piv txwv li, H62 tooj dag, nrog 62 feem pua tooj liab thiab 38 feem pua zinc, muaj lub zog tensile ntawm txog 370 MPa thiab elongation ntawm 25 feem pua, ntsuas lub zog thiab kev ua haujlwm.
Corrosion Resistance
The brass surface easily forms a dense zinc oxide or basic zinc carbonate protective film, showing good corrosion resistance in neutral or weak alkaline environments. Nyob rau hauv corrosive scenes xws li dej hiav txwv thiab cov huab cua ntub, nws cov corrosion kuj zoo dua li cov pa roj carbon zoo tib yam tab sis tsis muaj zog dua stainless hlau. Lead- muaj cov tooj dag xws li HPb59-1 tsis tsuas yog txhim kho kev ua haujlwm ntawm kev txiav, tab sis kuj txo kev sib txhuam los ntawm lubrication ntawm cov hlau lead, nrog rau cov txiaj ntsig tseem ceeb hauv cov khoom hnav-tiv taus.
Kev ua tau zoo
Brass rods muaj ntau yam ntawm kev ua kom haum. Thaum lub sijhawm ua haujlwm kub ntawm 600 txog 800 degrees C, lawv cov yas zoo dua li cov tooj liab ntshiab, haum rau extruding loj profiles. Thaum lub sijhawm ua haujlwm txias xws li kev kos duab txias thiab txias dov, hardness tuaj yeem tswj tau los ntawm kev kho cov ntsiab lus zinc kom tau raws li qhov yuav tsum tau muaj qhov tseeb ntawm qhov tseeb. Brass muaj kev ua tau zoo heev, tshwj xeeb tshaj yog cov hlau lead, nrog rau kev txiav ceev mus txog ob mus rau peb zaug ntawm cov tooj liab ntshiab thiab cov cuab yeej siv qis, txhim kho kev ua haujlwm zoo heev.
Tsis yog -Magnetic thiab Environmentally Friendly
Brass yog ib yam khoom uas tsis yog- sib nqus, uas yog ib qho tseem ceeb hauv electromagnetic shielding, siab - zaus circuits, thiab precision instruments rhiab rau magnetic teb. Nws muaj pes tsawg leeg ua tau raws li qhov yuav tsum tau ua ntawm RoHS Cov Lus Qhia, nrog cov hlau lead - dawb tooj dag variants muaj rau kev sib cuag zaub mov thiab daim ntawv thov khoom siv kho mob.
Cov ntawv thov kev lag luam
Hauv kev tsim khoom siv tshuab, tooj dag pas nrig yog qhov zoo tagnrho rau hnav- cov khoom tiv taus xws li iav, bearings, thiab li qub. Hauv kev tsim khoom hauv dej hiav txwv, tin- muaj cov tooj dag xws li HSn70-1 ua cov yeeb yaj kiab oxide ruaj khov thiab nyiam rau cov nkoj nkoj, cov kav dej hiav txwv, thiab cov ntawv ntim cov raj xa dej, nrog cov nqi txhua xyoo hauv cov dej hiav txwv qis dua li cov pa roj carbon zoo tib yam. Hauv cov khoom siv hluav taws xob, tooj dag qhov hluav taws xob ntawm li 25 mus rau 35 feem pua IACS ua ke nrog kev ua haujlwm yooj yim ua rau nws yog ib qho khoom siv rau cov khoom sib txuas, terminals, thiab relay springs. Hauv kev kho kom zoo nkauj vaj tsev, tooj dag xim thiab plasticity txhawb cov ntaub thaiv phab ntsa, cov duab puab, thiab sab hauv trim, nrog rau kev kho deg ua tiav cov xim los ntawm ci daj mus rau ntsuab tsaus.
Yav tom ntej Trends
Brass rods tab tom txhim kho mus rau kev ua haujlwm siab thiab ua haujlwm zoo. High-Zinc tooj dag txhim kho corrosion kuj los ntawm kev ntxiv npib tsib xee thiab txhuas rau qhov chaw hnyav dua. Environmentally friendly lead- tooj dag dawb siv microalloying los hloov cov qib coj ua ib txwm muaj thaum tswj kev txiav. Brass-raws li cov pas nrig sib xyaw nrog cov txheej txheem lubricating qhia tau tias muaj peev xwm siv tau hauv qhov siab- hnav cov xwm txheej xws li cov kabmob thiab cov ntsaws ruaj ruaj.
