一、电子信息产品制造业 电子信息产品制造业是铜加工材的三大主要消费行业之一。其代表品种主要是高精度异型带、电子引线框架材料及电解铜箔。在一个很长的时期内,Fe-Ni-Co合金材料占据着IC引线框架材料和电子管封装材料的绝对优势,随后Fe-Ni42合金以价格优势被大量地使用,从而替代了Fe-Ni-Co合金材料。自从铜合金以其独特的性能进入电子引线框架材料之列以后,发展极为迅速。目前常用的为Cu-Fe合金系的C19400、C19500、C19520、C19210和C19280;Cu-Sn合金系的C50710;Cu—Cr合金系的C18040;Cu—Ni—Si合金系的C64710、C64730和C70250等。市场上用量最大的
First, the electronic information products manufacturing Electronic information products manufacturing industry is one of the three major consumer copper processing materials. Its representative varieties are mainly high-profile shaped band, electronic lead frame material and electrolytic copper foil. Over a long period of time, Fe-Ni-Co alloy materials occupy the absolute advantages of IC lead frame materials and tube packaging materials. Fe-Ni42 alloys are subsequently used in large quantities at a competitive price, replacing Fe-Ni-Co Alloy materials. Since the copper alloy with its unique properties into the list of electronic lead frame materials, the development is extremely rapid. C19400, C19500, C19520, C19210 and C19280 currently used for Cu-Fe alloys; C50710 for Cu-Sn alloys; C18040 for Cu-Cr alloys; C64710, C64730 and C70250 for Cu-Ni-Si alloys .
