HPS 3 1/8" 6061 T6 Aluminum Straight Tubing is ideal for intake, cooling systems and turbo intercooler piping setup because 6061 aluminum is the most popular and versatile alloy, and is the least expensive of the heat treatable aluminum alloys. HPS straight aluminum round tubing is sold in the T6 condition, ideal for sawing, machining, sanding, and polishing. The aluminum tubing can be polished, but due to the softness of the aluminum, care must be taken not to remove too much material, especially in the area near any welds.
