ASTM B111 UNS C68700 CuZn20Al2 Aluminum Brass Tube For Oil and Gas Industry

ASTM B111 UNS C68700 CuZn20Al2 Aluminum Brass Tube For Oil and Gas Industry

The ASTM B111 UNS C68700 aluminum brass tube, also known as CuZn20Al2, is a high-strength and corrosion-resistant copper alloy widely used in industries requiring superior durability and reliability. This alloy is primarily composed of copper (Cu), zinc (Zn), and a small percentage of aluminum (Al), which enhances its mechanical properties and resistance to harsh environments.

Key Features:

1. Corrosion Resistance:

   • Excellent resistance to seawater and brackish water, making it ideal for marine and offshore applications.
   • Superior protection against dezincification and impingement attack.

2. High Strength:

   • The addition of aluminum increases its tensile strength and hardness.
   • Suitable for high-pressure and high-temperature environments.

3. Thermal and Electrical Conductivity:

   • Good thermal conductivity for efficient heat transfer.
   • Moderate electrical conductivity suitable for various applications.

4. Durability:

   • Long service life in aggressive and corrosive environments.
   • Low maintenance costs due to its excellent wear resistance.

Applications:

• Heat Exchangers: Ideal for cooling systems and condensers in power plants and ships.
• Marine Applications: Manufacturing of seawater desalination equipment and marine hardware.
• Chemical Processing: Used in evaporators and other equipment exposed to corrosive chemicals.
• Oil and Gas Industry: Suitable for offshore platforms and related infrastructure.
