Exceptional Mechanical Properties

Aluminum brass C 68700 tubes are designed to withstand rigorous industrial demands. With a high tensile strength above 340 MPa and elongation over 30%, these tubes deliver reliable performance and safety, making them suitable for thermal and mechanical stress environments such as power plants and heat exchangers.


Flexible Sizing and Finishing Options

Choose from a wide range of outer diameters (6 mm to 102 mm), thickness (0.5 mm to 10 mm), and customize your order in lengths up to 6 meters. Available with bright or polished finishes and ends in plain, beveled, or threaded styles, these tubes adapt to varied installation needs.


Corrosion Resistance for Industrial Use

The aluminum content in C 68700 brass enhances its resistance to corrosion, particularly from seawater and industrial fluids. This makes it highly suitable for long-term service in condensers, sugar mills, and power generation plants, reducing maintenance requirements and downtime.
