Copper Sawb rau Lead Ncej
Khoom Taw Qhia
Cov khoom siv rau cov ncej txhuas yog ib txwm ua los ntawm cov hlau alloy ntawm tooj liab, Hlau thiab phosphorus, lossis tooj liab, npib tsib xee thiab silicon, uas muaj cov hlau tsis sib xws ntawm C192 (KFC), C194 thiab C7025.Cov alloys no muaj zog thiab kev ua tau zoo.C194. thiab KFC yog cov neeg sawv cev tshaj plaws rau tooj liab, hlau thiab phosphorus alloy, lawv yog cov khoom siv alloy feem ntau.
C7025 yog cov alloy ntawm tooj liab thiab phosphorus, silicon. Nws muaj cov thermal conductivity siab thiab hloov tau yooj yim, thiab tsis xav tau kev kho cua sov, thiab nws 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 high density integrated circuits.
