Two common materials that scuba tanks are made from are steel and _________.

• A. Stainless steel
• B. Aluminum
• C. Titanium
• D. Carbon fiber

Answer: (B)

Scuba cylinders are built from materials that can safely handle high pressure, are durable, and are cost-effective. Aluminum is paired with steel because it provides a lighter option without sacrificing strength, making the tank easier to lift and handle while still withstanding the pressures involved. Aluminum also resists corrosion well in marine environments, which is important for equipment used in saltwater. Other materials like stainless steel, titanium, or carbon fiber exist in some specialized or high-end setups, but they’re not as widely used for standard scuba tanks due to factors like weight, cost, and manufacturing practicality.
