Exceptional Mechanical and Physical Properties

This aluminum brass alloy provides a robust combination of strength and flexibility, with a density of 8.4 g/cm, a tensile strength of 330 MPa, and yield strength of 100 MPa. Its high elongation over 25% means components can be shaped and manipulated without cracking, supporting complex designs in challenging environments.


Superior Corrosion Resistance for Demanding Environments

Specifically engineered to resist corrosion even in harsh seawater and industrial atmospheres, EN 12451 CuZN20 Al2As-CW 702R is ideal for marine structures, heat exchangers, and condensers. The alloys chemical stability prolongs service life and reduces maintenance costs, making it a trusted material worldwide.


Customizable Solutions for Diverse Applications

Available in various thicknesses (typically 0.5 mm 8 mm), outer diameters (6 mm 219 mm), and up to 6 meters in length, this alloy can be tailored to meet individual project needs. With options for hard, half hard, and soft tempers, as well as seamless extruded or drawn techniques, manufacturers ensure suitability across a range of technological demands.
