Kev lag luam Bronze Bushings peb feem ntau siv tsis yog tsuas yog ob alloys ntawm tin thiab tooj liab, tab sis kuj phosphorus, zinc, lead-nickel thiab lwm yam khoom. Cov alloys feem ntau muaj kev tiv thaiv corrosion, hnav tsis kam, thiab zoo txhua yam khoom. Cov yam ntxwv rau cov txheej txheem kev ua haujlwm ruaj khov.
Cov yam ntxwv ntawm lub tes tsho tin bronze, cov khoom siv no muaj ntau yam kev sib zog, yooj yim rau disperse shrinkage kab noj hniav, tsawg ntim shrinkage, tsis zoo compactness thiab lwm yam teeb meem. Cov tshuaj kuj yog ib qho yooj yim rau react nrog oxygen los tsim inclusions, uas yog sandwiched nyob rau hauv lub tes tsho tooj liab thiab txo cov neeg kho tshuab zog ntawm cov khoom nws tus kheej, yog li deoxidation yuav tsum tau ua kom zoo. Nws muaj qhov rhiab heev rau overheating thiab gases, yooj yim rau weld thiab braze, tsis muaj teeb meem ntawm kev cuam tshuam, tsis muaj hlau nplaum, yog txias resistant, thiab muaj kev hnav zoo heev.
Tin bronze tooj liab teeb muaj feem cuam tshuam rau cov ntsiab lus hlau, xws li phosphorus, zinc, lead, npib tsib xee, manganese, hlau, titanium, beryllium, zirconium, niobium, boron, txhuas, magnesium, thiab silicon, uas tseem tau hais hauv peb cov ntawv dhau los. Cov ntsiab lus ntawm cov ntsiab lus hlau yuav tsum tau tswj kom zoo, vim tias cov ntsiab lus yuav muaj kev cuam tshuam ncaj qha rau cov khoom.
