6061 aluminum sheet plate application

6061 aluminum alloy plate is known for its excellent corrosion resistance, high strength-to-weight ratio, good machinability, and good anodizing performance.

6061 aluminum sheet is one of the most popular use in various applications, including Automatic machine parts, mobile phone card slot, mobile phone case, mold, automobile, precision machining, mold manufacturing, electronics and precision instruments, structural engineering, and so on. 6061 T6 aluminum alloy plate has very high cost performance.

6061 T6 VS T651 / Why choose 6061 T651?

6061 T651 is a certain amount of stretching and flatting on the basis of T6 temper .Reduced the internal stress, not easy to deform when processing.
In general, if there are no precise requirements for dimensional stability and elastic allowance, aluminum alloy 6061 T6 is good enough; If for the precision workpiece, in order to avoid the processing of elastic recovery and size can not maintain stability, it is necessary to choose 6061 T651,Such as 3C products,Precision parts.
