MAIN CHARACTERISTICS 

CuSn6 provides an excellent combination of strength, cold formability and hardness. It is wear resistant, has good corrosion resistance and soldering properties. Due to its good machining properties it is used for all kind of springs, tubes or flexible tubes. Special characteristics such as superfine particle size or thermal-mechanical stress relieving improve mechanical properties and provide increased strength and greater malleability.

CuSn6 has a good resistance to seawater, different agents and industrial atmosphere and has a good resistance to tarnishing. It is in a large extend resistant to pitting corrosion.
