CuSn7Zn4Pb7 tin bronze graphite tooj liab tes tsho
CuSn7Zn4Pb7 graphite tooj liab lub tes tsho yog cov khoom sib xyaw uas sib xyaw ua ke ntawm CuSn7Zn4Pb7 tooj liab alloy thiab graphite. Cov hauv qab no yog cov ncauj lus kom ntxaws txog CuSn7Zn4Pb7 graphite tooj liab tes tsho:
Tshuaj muaj pes tsawg leeg:
Cov tshuaj tseem ceeb ntawm CuSn7Zn4Pb7 tooj liab alloy muaj xws li tooj liab (Cu), tin (Sn), zinc (Zn) thiab txhuas (Pb). Ntawm lawv, cov ntsiab lus ntawm tooj liab yog nyob nruab nrab ntawm 81.0-85.0%, cov ntsiab lus ntawm tin yog nruab nrab ntawm 6.0-8.0%, cov ntsiab lus ntawm zinc yog nruab nrab ntawm 2.{{10}}.
Lub tes tsho graphite tooj liab txhim kho nws tus kheej-lubricating zog los ntawm kev ntxiv graphite rau tooj liab alloy.
Lub cev thiab mechanical zog:
CuSn7Zn4Pb7 tooj liab alloy muaj zog nruab nrab, zoo tom tsis kam, zoo processability thiab nruab nrab corrosion kuj.
Vim tias lub tes tsho graphite tooj liab muaj graphite, nws muaj cov khoom zoo rau nws tus kheej lubricating, uas tuaj yeem txo qhov hnav thiab kub los ntawm kev sib txhuam ntau dhau thiab ua rau lub neej kev pab cuam ntawm cov khoom siv.
Cov hlau muaj qhov sib txawv ntawm qhov sib txawv ntawm 860-1020 degree, qhov ceev ntawm 8.8g / cm³, hluav taws xob conductivity ntawm 7.5 MS / m ntawm 20 degree, thiab thermal conductivity ntawm 64 (m * K) ^ ({{ 7}}).
Kev siv thaj chaw:
CuSn7Zn4Pb7 graphite tooj liab tes tsho feem ntau yog siv los ua qhov hnav-tiv taus thiab elastic ntsiab hauv kev lag luam, xws li bearings, bushings, tes tsho, thiab lwm yam.
Vim nws cov hluav taws xob zoo conductivity, hnav tsis kam thiab nws tus kheej lubricating zog, graphite tooj liab tes tsho yog dav siv nyob rau hauv lub hwj chim, aviation, shipbuilding thiab lwm yam teb, tshwj xeeb tshaj yog nyob rau hauv springs, keyboards, connectors thiab lwm yam teb uas yuav tsum tau high-kev ua tau zoo elasticity.
Txoj kev npaj:
Kev npaj ntawm graphite tooj liab lub tes tsho tooj liab feem ntau suav nrog cov kauj ruam ntawm kev npaj cov ntaub ntawv raw, casting, ntxhib tig, drilling, inlaying, nplua tig, zoo sib tsoo thiab tom qab ua tiav. Los ntawm cov kauj ruam no, kev ruaj khov ntawm graphite thiab tooj liab tuaj yeem ua kom ntseeg tau, kom lub tes tsho graphite tooj liab tuaj yeem ua tau raws li qhov yuav tsum tau siv zaum kawg.
