Problems solved by technology

[0011] 4. Due to the high strength of the 8 series alloy products, if the casting and cold rolling production process is not properly controlled, the production difficulty of the subsequent process will be increased
The product will also frequently break due to the difficulty of thinning, which affects the normal production and production efficiency of aluminum foil rolling. At the same time, this continuous abnormal adjustment is not conducive to the stability of the aluminum foil rolling process system and will destroy the entire production. The stability of the process will also have a negative impact on the production of other varieties
Therefore, the use of 8-series alloys to produce double-zero foils must solve the problem of high product strength and difficulty in thinning
