C5102 CuSn5 CuSn5 / CW451K C51000 /

Merit

CuSn5 provides an excellent combination of strength, excellent formability and hardness. It has a good electrical conductivity and corrosion resistance. Soldering and brazing properties are excellent.The temperature stability of this alloy allows application even at elevated service temperatures. Thermal relaxation is negligible at 100 °C and acceptable up t o 120 °C.
