ASTM B148 UNS C95800 - Nickel Aluminium / Aluminum Bronze
C95800 nickel aluminium (aluminum) bronze alloy is very strong.  It is renowned as having high strength and ductility which is retained at low temperatures, good shock & wear resistance, good casting qualities as well as being easy to machine. Additionally it is easy to weld and has good thermal and electrical conductivity properties.
It has exceptional corrosion resistance due to a tough oxide layer. Heat treatment further increases its seawater corrosion properties, making it an ideal choice in marine environments with the material being used for seawater valves and ships components.
