Introduction
Super alloys have the capacity to function at very high temperatures and severe mechanical stress. Nickel-based, cobalt-based, and iron-based alloys are three types of super alloys. They have good creep and oxidation resistance, and contain a number of elements in different combinations to achieve the desired result. Solid-solution hardening, work hardening, and precipitation hardening are performed for strengthening the super alloys.
Super alloy Nibry™ is a precipitation hardening nickel-based alloy. It has galling resistance property, and high corrosion resistance, strength, hardness and ductility. The following datasheet gives an overview of Nibry™.

Fabrication and Heat Treatment
Machinability
Nibry™ can be machined using conventional machining techniques. It is better to use a rigid machining set up. It is recommended to use cutting fluids, which are suitable for stainless steels and nickel alloys.
Forming
Nibry™ can be cold formed in the annealed condition.
Heat Treatment
Nibry™ can be precipitation hardened or aged at 372 to 705°C (700 to 1300°F).
Applications
Nibry™ can be used in the following:
- Pump parts
- Glass molds
- Valves
- Permanent casting molds
