Qhov txawv ntawm txhuas bronze ZCuAl9Fe4 thiab txhuas bronze ZCuAl9Fe4Ni4Mn2
Aluminium bronze ZCuAl9Fe4 thiab txhuas bronze ZCuAl9Fe4Ni4Mn2 ob leeg muaj lub zog siab thiab zoo hnav tsis kam, thiab tuaj yeem siv rau cov khoom uas muaj lub zog muaj zog xws li cov ntsia hlau, txiv ntseej, lub tes tsho tooj liab, lub nplhaib sib khi thiab lwm yam hnav-tiv taus.
Cov ntsiab lus txhuas ntawm txhuas bronze feem ntau tsis tshaj 11.5%, thiab qee zaum tsim nyog cov nyiaj ntawm hlau, npib tsib xee, manganese thiab lwm yam khoom ntxiv los txhim kho kev ua tau zoo. Aluminium bronze tuaj yeem ua kom sov-kho thiab ntxiv dag zog, thiab nws lub zog yog siab dua li ntawm tin bronze, thiab nws qhov kev tiv thaiv kub kub oxidation kuj zoo dua. Aluminium bronze uas muaj cov hlau thiab manganese muaj zog thiab hnav tsis kam. Tom qab quenching thiab tempering, lub hardness yuav nce. Nws muaj qhov kub thiab txias corrosion kuj thiab oxidation tsis kam. Nws muaj corrosion kuj zoo nyob rau hauv cov huab cua, dej tshiab thiab seawater, thiab muaj machinability zoo. Nws tuaj yeem welded tab sis tsis yooj yim brazed, thiab nws muaj kev ua haujlwm zoo nyob rau hauv lub xeev kub.
QAl{0}} aluminium bronze
Qib: ZCuAl9Fe4
Txuj: GB / T 13808-1992
Cov yam ntxwv thiab kev siv: Nws yog ib qho txhuas bronze uas muaj hlau, muaj zog thiab kev sib txhuam, zoo corrosion kuj, zoo siab ua nyob rau hauv kub lub xeev, thiab yuav welded los ntawm hluav taws xob welding thiab roj welding, tab sis lub brazing kev kawm tsis zoo. 9-4 txhuas bronze tuaj yeem siv los hloov cov hlau tin hnav-resistant bronze.
