Phosphor bronze yog ib qho alloy ntawm tooj liab, tin, thiab phosphorus. Nws yog ib qho nyuaj thiab siv tau los ua cov springs. Siv P tshem tawm cov pa tawm ntawm cov tooj liab dawb thiab tooj liab (Cu-Sn) thiab tawm me me ntawm P, thiab ntxiv 1 feem pua P rau Cu alloy los txhim kho cov khoom siv kho tshuab (tawv tawv, elasticity, hnav tsis kam, corrosion resistance). Feem ntau yog siv los ua qhov hnav-tiv taus thiab elastic ntsiab. Khoos phib tawj connectors, txawb xov tooj connectors, high-tech kev lag luam connectors, hluav taws xob thiab hluav taws xob springs, keyboards, hluav taws xob khoom slots, nyees khawm, hluav taws xob connectors, lead thav duab, vibrators thiab terminals, thiab lwm yam. Muaj feem xyuam rau kev hnav-resistant qhov chaw thiab elastic Cheebtsam metallurgical engineering ntawm Cov ntsiab lus Basic muaj pes tsawg leeg cov ntsiab lus 2 feem pua rau 8 feem pua tin, 0.1 feem pua rau 0.4 feem pua phosphorus, thiab lwm yam.
