Why choose aluminum supplier Chalco?
When choosing housing materials for mobile phones, digital and electronic products, the stability and machinability of aluminum plates are key to ensure that the aluminum housing resists pressure and protects electronic components. Used as a shell, the anodizing process is also an important factor, which can improve the corrosion resistance and hardness of the aluminum plate, and achieve various appearance effects. The 3C digital aluminum plate produced by Chinalco complies with ASTM B209 (American aluminum plate industry standard) and EN 485 (European aluminum plate industry standard) standards.
Chalco cooperates with many well-known digital 3C brands, including Apple, Huawei, Xiaomi, Samsung, LG, Konka and other Fortune 500 companies.
Chalco has a complete set of advanced material research and development, testing, and analysis instruments, which can meet the requirements of digital electronic structural parts such as stable structural strength, good formability, high hardness, and long service life. It can be easily punched, bent, Deep drawing, welding and other processing.
