Aluminum flat bar for lens holder of mobile phone in 6063-T5 alloy

●High purity 6063-T5 alloy to avoid defects in anodizing process. (Usually aluminum bar only accounts for less than 10% of the total costs of aluminum lens holder, to control the costs of producing lens holder, the good rate of aluminum bar need to be not less than 95%,so high purity of alloy is critical)
●High grade grain size of alloy, which ensures the effect of anodizing to be the best. As high end consumer products, mobile phone have highest requirements for appearance, no any defects on the surface can be found.
●Precise dimension and flatness, which makes possible to milling several lens holder on 1pc of aluminum flat bar. This helps to reduce the production costs and increase the efficiency of lens holders.
