Aluminum alloy strip for mobile phone shell formed by stamping and deep drawing

Abstract

The invention discloses an aluminum alloy strip for a mobile phone shell formed by stamping and deep drawing. The aluminum alloy consists of the following components in percentage by weight: 0.5 to 0.8 percent of Si, 0.05 to 0.15 percent of Fe, 0.03 to 0.08 percent of Mn, 1.5 to 3.5 percent of Mg, 0.01 to 0.08 percent of Ce, 0.2 to 0.3 percent of Ti and the balance of Al.

Description

technical field [0001] The invention relates to the field of aluminum alloys, in particular to an aluminum alloy strip for stamping and deep-drawing forming of mobile phone casings. Background technique [0002] At present, with the improvement of living standards, people's demand for mobile phones has also increased to a very high level, which puts forward higher requirements for the appearance of corresponding mobile phones. Traditional plastic shell products are increasingly unable to meet people's needs. Demand, the metal shell mobile phone has a very strong metal texture, which can bring unparalleled visual impact. At the same time, it has the advantages of delicate hand feeling, wear resistance, drop resistance, and corrosion resistance. It is highly respected by consumers and represents high-end electronic products. direction of development. [0003] The metal materials used in the mobile phones with metal shells that have been adopted at present include magnesium al...

Problems solved by technology

The molding yield of mobile phone shells made of existing aluminum alloy grades is generally only 70-80%. The common problems are low yield, poor surface appearance quality, and casting defects such as streamline marks, spots, and looseness on the surface. , it is difficult to ensure the smooth and smooth surface quality requirements of the mobile phone shell, and it brings a great burden of surface renovation work, which seriously restricts the production capacity of aluminum alloy enterprises and increases the production cost

Products and methods in the prior art cannot meet the needs of mobile phone casings
