Copper Sawb rau Lead Ncej
Khoom Taw Qhia
Cov khoom siv rau cov hlau lead yog ib txwm ua los ntawm alloys ntawm tooj liab, Hlau thiab phosphorus, los yog tooj liab, npib tsib xee thiab silicon, uas muaj cov alloy No. C192 (KFC), C194 thiab C7025.Cov alloys muaj lub zog thiab kev ua tau zoo.C194 thiab KFC yog cov feem ntau tus neeg sawv cev rau tooj liab, hlau thiab phosphorus alloy cov ntaub ntawv.
C7025 yog cov alloy ntawm tooj liab thiab phosphorus, silicon. Nws muaj thermal conductivity thiab siab yooj, thiab tsis xav tau kev kho cua sov, kuj yog ib qho yooj yim rau stamping. Nws muaj lub zog siab, zoo heev thermal conductivity zog, thiab zoo heev rau cov hlau thav duab, tshwj xeeb tshaj yog rau kev sib dhos ntawm cov khoom siv hluav taws xob sib xyaw ua ke.
