Luxfer Product Specifications

Luxfer L6X® Aluminum Cylinder Specifications

In 1988, Luxfer introduced scuba tanks manufactured from L6X®, a proprietary formula of aluminum alloy 6061-T6 developed by Luxfer metallurgists to provide superior corrosion-resistance and dependable performance in the most demanding underwater environments.

Compared to conventional alloys, L6X has been optimized to improve durability, fracture toughness and resistance to cracking and tearing, even under high pressures over long periods. More than 50 million Luxfer cylinders manufactured from L6X alloy have an exemplary record for safety, long service life and reliable performance.

Luxfer L6X® Hoop-Wrapped Cylinder Specifications

In Introduced in 1976, Luxfer hoop-wrapped composite cylinders consist of an aluminum SCBA cylinder with its barrel reinforced with high-strength fiberglass or carbon wrapping to permit higher-pressure filling. Up to 40% lighter in weight than comparable steel cylinders, Luxfer hoop-wrapped SCBA cylinders are non-magnetic and extremely corrosion resistant—unlike corrosion-prone steel cylinders.

Since 1988, Luxfer has manufactured the aluminum liner of these cylinders from its own proprietary version of 6061-T6 alloy. Now marketed as L6X®, this exclusive aluminum-magnesium-silicon formula was specifically designed by Luxfer metallurgists to provide improved durability, fracture toughness and resistance to tearing and cracking. More than 40 million L6X all-metal and composite cylinders in service around the world have an exemplary record for safety and dependability. Manufactured to all recognized international standards, L6X hoop-wrapped SCBA and life-support cylinders are available in a broad range of sizes and capacities.
