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 high strength and good spring properties combined with good machining properties it is used for all kind of springs, Bourdon tubes or flexible metal tubes. Special characteristics such as superfine particle size or thermal- mechanical stress relieving improve mechanical properties and provide increased strength and greater malleability. The alloy is registered US EPA antimicrobial.
