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.
