Abstract

The invention discloses a process for producing medium gauge aluminum foil for an 8150 blank. The defects that existing medium gauge aluminum foil produced by 1000-series alloy is low in tensile strength and ductility, easy to crack in the stamping process and low in yield are overcome. The medium gauge aluminum foil comprises iron, silicon, copper, manganese, titanium, chromium, zinc, cadmium, lithium, lead, magnesium and aluminum. The production process comprises the steps of intermediate rolling, thickness shearing and annealing packaging. The processed medium gauge aluminum foil for an 8150 alloy container is extremely good in tensile strength, ductility and other properties, not easy to crack in the stamping process and high in yield.

Description

technical field [0001] The invention relates to a process for producing single zero aluminum foil from 8150 blank. Background technique [0002] Aluminum is the most abundant metal element in the earth's crust, and its content accounts for about 8.8% of the total mass of the earth's crust. Aluminum in nature exists in the form of compounds, and about 70% of the aluminum in the earth's crust is made of Al 2 o 3 form exists in nature. Aluminum and aluminum alloy products are widely used in the packaging industry, transportation industry, and construction industry, of which the packaging industry accounts for about 18.5%. Aluminum is a good packaging material for food, beverages, medicines, cosmetics and other items. Its uses are becoming more and more extensive, and its consumption is increasing year by year. [0003] China has now become a major producer of primary aluminum and aluminum products, and a net exporter of aluminum processed products. Aluminum processing produ...
