Because Germany sunshine battery materials can't be absolutely pure, and positive plate metal, lead antimony alloy with the grid frame itself constitutes a battery pack.
由于德国阳光蓄电池材料不可能绝对的纯，且正极板与栅架金属(铅锑合金)本身也构成电池组。
Copper alloys for lead frame are becoming leading factor in the lead frame materials for IC, because of its high strength and high conductivity.
铜合金引线框架材料因其高强高导电性能而成为集成电路框架材料的主体。
