摘　　要：通过对电容器用铸轧3003铝合金阴极铝箔的中间热处理进行研究。研究发现,在450℃左右的中间热处理条件下,合金退火晶粒大小合适、第二相化合物析出均匀细小,电阻率较低,有利于成品腐蚀获得均匀细小的海绵状孔,从而获得较好的腐蚀性能。The intermediate heat treatment of cast-rolled 3003 aluminum alloy cathode aluminum foil for capacitors was studied.It is found that under the conditions of intermediate heat treatment at about 450℃,the alloy annealing grain size is suitable,the second phase compound precipitation is uniform and fine,and the resistivity is low,which is conducive to the corrosion of the finished product to obtain uniform and fine cavernous holes,so as to obtain better corrosion performance.
