Abstract

The invention discloses an aluminum foil for an electronic tag with low pinholes and a high finish degree. The aluminum foil for the electronic tag with the low pinholes and the high finish degree comprises the following raw materials in percentage by weight: 0.15 to 0.3 percent of Si, 0.03 to 0.06 percent of Cu, 0.05 to 0.15 percent of Zn, 0.08 to 0.10 percent of Mn, 0.05 to 0.10 percent of Ti, 0.3 to 0.7 percent of Fe, 0.05 to 0.06 percent of Ni, 0.005 to 0.006 percent of Cr, 0.006 to 0.008 percent of Cd, 0.005 to 0.006 percent of Pb, 0.006 to 0.008 percent of Sn, 0.006 to 0.008 percent of Zr, and the balance Al, wherein the weight percentage of the Fe and the Si satisfies the relationship according to the following formulas: Fe / Si is equal to 2 to 3, and Fe+Si is less than or equal to 1percent. The aluminum foil produced by the invention solves the problems of rolled dark lines, tissue lines, easiness in causing strip breakage and the like encountered in the aluminum foil production process.

Description

technical field [0001] The invention belongs to the technical field of aluminum foil production, and more specifically relates to an aluminum foil for an electronic label with low pinholes and high smoothness and a production process thereof. Background technique [0002] Aluminum foil has a wide demand in light industry, power electronics industry, packaging and other fields due to its unique properties. As a major producer of aluminum sheet, strip, and foil materials, China's current domestic production capacity of aluminum foil significantly exceeds demand. With the development of my country's proactive fiscal policy, it has stimulated the consumption of domestic aluminum foil products, and at the same time supports aluminum processing to develop high value-added products, such as high-precision aluminum strips. , double-zero foil, etc., to realize the industrialization of new non-ferrous metal materials. [0003] Electronic label is also one of the wide applications of a...
