Aluminum 2024-T351 Round Tube 3-1/4" OD x 1/4" wall Retail Price

About 2024|High-strength aluminum with copper as the primary alloying element. Machines well with good chip formation, closer to 7075 than 6061 in how it cuts. Excellent fatigue resistance, which is why it shows up constantly in aerospace structural parts like fuselage and wing components. The tradeoff is poor corrosion resistance (much worse than 6061) and it’s essentially non-weldable. Typically needs protective coatings like Alclad in corrosive environments. Costs more than 6061, less than 7075, and sits between them in strength. If you need more strength than 6061 but your budget or application doesn’t justify 7075, 2024 is worth considering.

About Round Tube|Hollow cylindrical stock for sleeves, bushings, spacers, and hydraulic cylinders. DOM (drawn over mandrel) tubing machines well and holds tight tolerances. Welded-seam structural tube is for cutting and welding, not precision work.
