MAIN CHARACTERISTICS 

CuSn8 strips provide a better corrosion resistance compared to bronze with lower tin-content, combined with higher strength. It is wear resistant, has excellent spring properties, good cold forming and soldering properties. CuSn8 is used for springy applications where high strength and wearresistance are required. Special characteristics such as superfine particle size or thermalmechanical stress relieving improve mechanical properties and provide increased strength and greater malleability.

It is resistant to seawater and industrial atmosphere. Largely insensitive to stress corrosion cracking.
