For consideration of aluminum alloy pipes and rods

Here we list the types and properties of UACJ's most representative aluminum alloys (alloy pipes and rods), including their applications.
As the product classifications of the former Furukawa-Sky Aluminum Corp. and Sumitomo Light Metal Industries, Ltd. differ in some cases, these are also provided for reference purposes.
