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 ntawm aluminium bronze feem ntau tsis tshaj 11.5%, thiab qee zaum tsim nyog cov nqi ntawm cov hlau, npib tsib xee, manganese thiab lwm yam khoom ntxiv los txhim kho kev ua tau zoo. Aluminium bronze tuaj yeem ua kom muaj zog los ntawm kev kho cua sov, nws lub zog yog siab dua tin bronze, thiab nws tsis kam mus rau 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 tuaj yeem txhim kho. Nws muaj qhov kub zoo corrosion kuj thiab oxidation tsis kam. Nws muaj qhov zoo corrosion kuj nyob rau hauv cov huab cua, dej tshiab thiab dej hiav txwv. Zoo, lub machinability tau txais, nws tuaj yeem welded thiab tsis yooj yim rau fiber ntau vuam, thiab kev ua haujlwm siab nyob rau hauv kub kub yog qhov zoo.
