7003 aluminum bar profile

7003 aluminum alloy is a kind of aviation aluminum material with higher strength and lighter weight than the ordinary 6 series aluminum alloy on the market. However, due to its high strength, the traditional forming process is more difficult. Its processing technology is generally that the aluminum bar is melted and extruded to obtain aluminum materials with different cross-section shapes.

At present, most of the mobile phone shells are made of plastic, and some of the high-end mobile phone shells are made of 6063 or 6061 aluminum alloy. The plastic shell can not be compared with the aluminum alloy shell in terms of texture and effect. However, 6xxx aluminum alloy shell is easy to break and deform due to its strength. However, due to the grain structure of 7003 aluminum alloy plate processed by direct extrusion, the surface effect after anode is not good.

The 7003 aluminum bar profile production process for mobile phone shell can not only meet the surface quality requirements after anodization, but also solve the problem of insufficient strength of 6 series aluminum alloy shell.

7003 aluminum bar profile production process is used for mobile phone shell. Through the adjustment of formula and processing technology, it can not only meet the surface quality requirements after anodization, but also solve the problem of insufficient strength of 6 series aluminum alloy shell; The strength of the existing 6 series aluminum alloy is: tensile strength 260mpa, yield strength 240mpa, ductility 8-12%; The tensile strength of 7003 alloy is 400MPa, yield strength is 340mpa and ductility is 9-12%.
