The Luxfer cylinder inner shell is made from which material?

• A. 6061 "T6" Aluminum Alloy
• B. Stainless Steel
• C. Carbon Fiber
• D. Magnesium Alloy

Answer: (A)

The inner liner of a Luxfer SCBA cylinder is made from 6061-T6 aluminum alloy. This material provides the essential combination of high strength-to-weight, good corrosion resistance, and formability needed to create a thin, durable inner shell that can safely contain high-pressure breathable air. In these cylinders, the heavy lifting for strength comes from the outer reinforcement (the overwrap, often carbon fiber or other composites), while the inner liner simply needs to be a reliable, compatible containment layer. Stainless steel would add unnecessary weight, carbon fiber is used for the outer reinforcement rather than the inner shell, and magnesium alloy is more prone to corrosion and other issues in this application.
