(1) 1235 alloy and 8011 is double zero foil test results

According to the corresponding testing scheme to the contrast test of 1235 alloy and 8011 alloy, and then on the surface of the product quality, pinhole, such as mechanical properties were tested. Test and the test results show that 1235 alloy production by two kinds of production process of aluminum foil surface quality was not obvious difference, and 8011 alloy aluminum foil products more excellent surface quality, dark side close short, stripes. However, before annealing, line, surface tension eased after annealing, explained in two kinds of alloy double zero foil surface quality, homogenizing annealing process does not directly impact.

In terms of pinhole situation, after homogenizing annealing of 1235 alloy double zero foil per square metre about 177-207 or so of the pinhole. USES the normal process of aluminum foil, about 243-638 of every square metre about pinhole. For the 8011 alloy, both the products of the production process pinhole number more than 1235 alloy, and is relatively close small pinhole. This means that the homogenizing annealing process for the good of 1235 alloy double zero foil pinhole to reduce. For 8011 alloy, the current iron silicon than pinhole reduce some disadvantages, so you need to adjust.

In the middle of the mechanics performance, the influence of annealing process of 1235 alloy is larger. The first 1235 alloy production technology adoption and homogenizing annealing and 0.4 mm intermediate annealing, produce the aluminum foil products performance is lower than normal intermediate annealing aluminum foil, high elongation. For 8011 alloy, two kinds of different annealing processes produce difference is low, the mechanical performance of aluminum foil products have 95 mpa tensile strength of 105 mpa.
