Description

ASTM B111 UNS C68700 Aluminum Brass Tube Seamless Heat Exchanger Tube

C68700 is indeed classified as a type of brass, specifically an aluminum brass alloy. This alloy typically contains copper, aluminum, and other elements, including arsenic, which contributes to its properties. There are various common copper alloys such as C12000, C44300, C68700, C70600, C71500, C71640. People choose material determine whether the alloy will be exposed to corrosive environments (like seawater, chemicals, or humidity). Some alloys are better suited for marine or chemical applications. Evaluate the operating temperature range, some alloys perform better at higher or lower temperatures.

The Properties of ASTM B111 C68700 copper alloy tube

  1. Corrosion Resistance: C68700 is known for its excellent resistance to corrosion in freshwater and moderately corrosive environments, making it suitable for various applications. The presence of aluminum and arsenic enhances its durability.

  2. Strength and Durability: The alloy offers good mechanical strength and can withstand wear and tear, making it appropriate for demanding applications.

  3. Ductility: C68700 is relatively ductile, allowing for easy shaping and forming, which is crucial in manufacturing processes.

  4. Biofouling Resistance: Like other copper alloys, C68700 is less likely to support the growth of marine organisms, which is beneficial for marine applications.
