NICKEL BASED
ALLOYS
Nickel-based alloys are a group of metallic materials that contain a significant amount of nickel along with other elements. These alloys exhibit excellent corrosion resistance, high-temperature strength, and a wide range of mechanical properties, making them suitable for various applications in industries such as aerospace, chemical processing, power generation, and marine engineering.
Our nickel-based alloys have properties which offer superior performance in demanding applications:
- Ni-Cu and Ni-Mo alloys for strongly reducing environments
- Ni-Cr alloys for strongly oxidizing environments
- Ni-Cr-Mo alloys for mixed environments
- Ni-Cr-Plus alloys for elevated temperature applications
It’s worth noting that the properties and performance of nickel-based alloys can vary depending on the specific composition and heat treatment processes used. Different alloys within the nickel-based alloy group have varying strengths, temperature limits, corrosion resistance, and other properties, so it’s essential to select the appropriate alloy for a given application based on its specific requirements.
