Nickel Alloy Castings:

Nickel base alloys have a high resistance to chemical corrosion and maintain good mechanical properties at elevated temperatures.  Some uses include nozzle diaphragms in jet engines, chemical processing and handling equipment, the pulp and paper industries, and specialty pumps and valves.
