Phosphor bronze thiab tooj dag yog ob chav kawm dav ntawm tooj liab alloys. Qhov sib txawv yog nyob ntawm cov khoom sib txawv thiab kev siv cov khoom xyaw.
Brass: Brass yog ib qho alloy uas muaj tooj liab thiab zinc. Yog tias nws tsuas yog tsim los ntawm tooj liab thiab zinc, nws yog hu ua tooj dag zoo tib yam. Yog tias muaj ntau yam alloys uas muaj ntau tshaj ob lub ntsiab lus hu ua tooj dag tshwj xeeb. Xws li tooj liab alloy muaj cov hlau lead, tin, manganese, nickel, lead, hlau, silicon. Brass muaj zog hnav tsis kam.
Phosphor bronze yog bronze nrog tin thiab phosphorus ua lub ntsiab alloying ntsiab. Muaj {{0}}% tin, 0.1-0.4 feem pua phosphorus, thiab tus so yog tooj liab. Cov qib tseem ceeb: Tuam Tshoj QSn10-1, QSn6.5-0.1, QSn7-0.2, QSn8-0.3, QSn4-0.3, QSn{ {14}}, ZQSn10, ZQSn5-5-5, ZQSN{17}}, thiab lwm yam.
