Compressor blades can be made from which materials?

Compressor blades can be made from which materials?

• A. Steel, Aluminum, or Titanium
• B. Plastic
• C. Copper
• D. Ceramic

Answer: (A)

Compressor blades must be made from materials that combine high strength, light weight, and good high‑temperature performance to withstand the stresses and speeds inside a jet engine. Steel, aluminum, and titanium alloys provide that balance: they’re strong enough to resist bending and fatigue, light enough to reduce rotor weight, and capable of withstanding the temperatures encountered in compression stages. Plastic cannot endure the heat or the immense mechanical stresses of high-speed rotation. Copper is too heavy and lacks the necessary strength and temperature capability. Ceramics, while heat resistant, are brittle and prone to catastrophic failure under impact and thermal cycling in a rotating blade, making them unsuitable for standard compressor blades.
