Qhov txawv ntawm tooj dag thiab tooj dag

Bronze muaj npe rau nws cov xim xiav, thiab tooj dag yog lub npe rau nws cov xim daj.Yog li qhov yooj yim cov xim tuaj yeem ua qhov txawv txav.Yuav kom paub meej nruj, kev tshuaj xyuas metallographic kuj tseem yuav tsum tau ua.

Cov xim ntsuab tsaus uas koj hais no tseem yog xim ntawm xeb, tsis yog xim tiag tiag ntawm bronze.

Cov hauv qab no qhia qee qhov kev paub yooj yim ntawm tooj liab alloys:

tooj liab alloy

Copper alloys yog tsim los ntawm kev ntxiv cov ntsiab lus alloying (xws li zinc, tin, aluminium, beryllium, manganese, silicon, npib tsib xee, phosphorus, thiab lwm yam) rau cov tooj liab ntshiab.Copper alloys muaj hluav taws xob zoo conductivity, thermal conductivity thiab corrosion kuj, nrog rau siab zog thiab hnav tsis kam.

Nyob ntawm seb muaj pes tsawg leeg, tooj liab alloys muab faib ua tooj dag thiab tooj liab.

1. Brass yog tooj liab alloy nrog zinc ua lub ntsiab alloying.Raws li cov tshuaj muaj pes tsawg leeg, tooj dag muab faib ua tooj liab zoo tib yam thiab tooj dag tshwj xeeb.

(1) Ordinary tooj dag Ordinary tooj dag yog tooj liab-zinc binary alloy.Vim nws cov yas zoo, nws tsim nyog rau kev tsim cov phaj, tuav, xov hlau, cov kav dej thiab cov khoom sib sib zog nqus, xws li cov kav dej condenser, cov kav dej txias thiab cov khoom siv tshuab thiab hluav taws xob.Brass nrog qhov nruab nrab tooj liab cov ntsiab lus ntawm 62% thiab 59% kuj tuaj yeem cam khwb cia thiab hu ua tooj dag.

(2) Cov tooj dag tshwj xeeb 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 khoom raug ntxiv rau tooj liab-zinc alloy los tsim cov tooj dag tshwj xeeb.Xws li txhuas tooj dag, tin tooj dag, txhuas tooj dag, silicon tooj dag, manganese tooj dag, thiab lwm yam.

Lead tooj dag muaj kev ua tau zoo heev thiab hnav tsis kam, thiab yog siv dav hauv kev tsim cov khoom saib, thiab raug cam khwb cia ua cov kabmob bushings thiab bushings.

Tin tooj dag muaj qhov zoo corrosion kuj thiab yog siv dav hauv kev tsim cov nkoj nkoj nkoj.

Aluminium nyob rau hauv txhuas tooj dag tuaj yeem txhim kho lub zog thiab hardness ntawm tooj dag thiab txhim kho nws cov corrosion kuj nyob rau hauv cov huab cua.Aluminium tooj dag yog siv los tsim cov khoom tiv thaiv corrosion.

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.

tooj liab

Bronze Ameslikas hais txog tooj liab-tin alloy, tab sis kev lag luam yog siv los hu rau tooj liab alloys uas muaj txhuas, silicon, lead, beryllium, manganese, thiab lwm yam kuj bronze, yog li bronze yeej muaj xws li tin bronze, txhuas bronze, txhuas bronze, beryllium bronze, silicon bronze, txhuas bronze, thiab lwm yam. Bronze kuj muab faib ua ob pawg: xovxwm-ua haujlwm bronze thiab cam khwb cia tooj liab.

(1) Tin bronze tooj liab-raws li alloy nrog tin raws li lub ntsiab alloying caij hu ua tin bronze.Feem ntau ntawm cov tin bronze siv hauv kev lag luam muaj cov ntsiab lus tin ntawm 3% thiab 14%.Tin bronze nrog cov ntsiab lus tin tsawg dua 5% yog tsim rau kev ua haujlwm txias;tin bronze nrog cov ntsiab lus tin ntawm 5% mus rau 7% yog haum rau kev ua haujlwm kub;tin bronze nrog cov ntsiab lus tin ntau tshaj 10% yog tsim rau casting.Tin bronze yog dav siv nyob rau hauv shipbuilding, tshuaj lom neeg kev lag luam, machinery, instrumentation thiab lwm yam lag luam.Nws yog tsuas yog siv los tsim cov khoom hnav-resistant xws li bearings thiab bushings, elastic Cheebtsam xws li springs, thiab anti-corrosion thiab anti-magnetic qhov chaw.

(2) Aluminium bronze tooj liab-raws li alloy nrog txhuas raws li lub ntsiab alloying yog hu ua txhuas bronze.Cov khoom siv ntawm txhuas bronze yog siab dua li cov tooj dag thiab tin bronze.Cov ntsiab lus txhuas ntawm cov khoom siv txhuas txhuas bronze yog nruab nrab ntawm 5% thiab 12%, thiab aluminium bronze nrog txhuas cov ntsiab lus ntawm 5% mus rau 7% muaj qhov zoo tshaj plaws plasticity thiab haum rau kev ua haujlwm txias.Thaum cov ntsiab lus txhuas ntau dua 7% mus rau 8%, lub zog nce, tab sis cov yas txo qis, yog li nws feem ntau yog siv rau hauv lub xeev li-cam khwb cia lossis tom qab ua haujlwm kub.Kev puas tsuaj thiab corrosion kuj ntawm txhuas bronze nyob rau hauv cov huab cua, seawater, seawater carbonic acid thiab feem ntau cov organic acids yog siab tshaj cov tooj dag thiab tin bronze.Aluminium bronze tuaj yeem tsim cov iav, bushings, cab iav thiab lwm yam muaj zog hnav-tiv taus qhov chaw thiab elastic Cheebtsam nrog siab corrosion kuj.

(3) Beryllium bronze Cov tooj liab alloy nrog beryllium raws li lub hauv paus ntsiab lus hu ua beryllium bronze.Cov ntsiab lus ntawm beryllium ntawm beryllium bronze yog 1.7% mus rau 2.5%.Beryllium bronze muaj siab elastic txwv thiab qaug zog txwv, zoo heev hnav tsis kam thiab corrosion kuj, zoo hluav taws xob conductivity thiab thermal conductivity, thiab kuj muaj qhov zoo ntawm tsis-sib nqus, tsis muaj txim thaum muaj kev cuam tshuam.Beryllium bronze feem ntau yog siv los ua qhov tseem ceeb rau cov cuab yeej precision, moos iav, bearings thiab bushings ua haujlwm nyob rau hauv kev kub ceev thiab kev kub siab, nrog rau vuam tshuab electrodes, cov cuab yeej tawg, nautical compasses thiab lwm yam tseem ceeb.
