    Extreme-Strength AHSS Carbon Steel Round Tubes

    Image of Product. Front orientation. Steel. Extreme-Strength AHSS Carbon Steel Round Tubes.
    The same steel used in automobile bodies, this AHSS (advanced high-strength steel) allows you to fabricate high-strength parts using thinner material than you could with other types of steel. It is formable, weldable, and more economical than alloy steel. It's sometimes called HSLA (high-strength low-alloy) steel.

    Ultra-Conductive 101 Copper Round Tubes

    Image of Product. Front orientation. Copper. Ultra-Conductive 101 Copper Round Tubes.
    The purest, most conductive copper we offer, with at least 99.95% copper content. Since there’s virtually no oxygen to outgas, it won’t break high-vacuum systems. It also won’t contaminate clean rooms, such as in semiconductor manufacturing.

    Tubes Sold

    Separately

    Slide these tubes into the next larger size and weld them together to create secure, custom tubing. Made of 122 copper, they’re easier to weld and braze than other copper tubes because they contain phosphorous. They won’t corrode from water, soil, or weather, making them a good choice for plumbing and underground systems.

    Highly Formable Marine-Grade 5086 Aluminum Round Tubes

    Image of Product. Front orientation. Aluminum. Highly Formable Marine-Grade 5086 Aluminum Round Tubes.
    The best marine-grade aluminum alloy to shape, 5086 bends into curves and corners without cracking. It won’t weaken in salt water, so it’s often formed into drums that transport fuel and oil overseas. It even stays strong at cryogenic temperatures, making it a common choice for cold boxes on offshore platforms.
