    L6X® aluminum medical cylinders

    Our L6X all-metal oxygen cylinders are manufactured from our exclusive L6X aluminum alloy, our proprietary formula of 6061 alloy.

Luxfer metallurgists, among the most recognized experts in the industry, developed this corrosion-resistant blend specifically to provide excellent performance in the most demanding high-pressure applications. Compared to conventional versions of 6061 alloy, Luxfer’s L6X has been optimized to improve durability, fracture toughness and resistance to tearing and cracking, even under high-pressure loads over long periods.

Because of the unique performance characteristics of L6X alloy, Luxfer has consistently passed all extensive, rigorous testing performed by major global gas companies and met or exceeded requirements set by every major cylinder regulatory authority in the world. Widely used in home oxygen therapy, emergency medical services and medical institutional applications in more than 50 countries, the more than 50 million cylinders Luxfer has manufactured from L6X alloy have an outstanding record for safe, dependable performance.

Luxfer aluminum cylinders are cycle-tested in excess of 100,000 cycles at service pressure to ensure dependable performance. Up to 40% lighter in weight than comparable steel cylinders, Luxfer aluminum cylinders are also highly corrosion-resistant and well suited to low-temperature applications.
