Q1: What is the main difference between 6063 and 6061 aluminum round bars?
A: 6063 offers a superior surface finish and better response to anodizing, making it ideal for architectural and decorative uses. 6061 provides higher mechanical strength, making it better suited for heavy structural load-bearing applications.
Q2: What is your Minimum Order Quantity (MOQ) for 6063 aluminum round bar?
A: Our standard MOQ is 500 kg per diameter. Smaller trial orders or sample cut pieces can be supplied for stocked inventory dimensions.
Q3: Can you supply pre-anodized or custom cut-to-length 6063 bars?
A: Yes, we offer precision band saw cutting with tight length tolerances, as well as clear, black, or custom color anodized surface finishes to meet your exact specifications.
