C95800/CuAl10Fe5Ni5

Characteristic
Construction material with high strength values, resistant in cold and even hot seawater. Very
good thermal stability and fatigue strength in air and seawater. Highly resistant to cavitation
and corrosion. Good lubrication is required when there is sliding stress. Very good pressure
tightness and weldability. Highly stressed slide bearing and worm rims. High-pressure steam
fitting, fittings for aggressive waters, pump housing.
