Nilo 36 - Low Expansion Alloy
Nilo 36 is a nickel-iron alloy with a low coefficient of thermal expansion, typically used in applications requiring precision dimensional stability and minimal expansion when exposed to temperature changes. This alloy, primarily composed of nickel and iron, is known for its excellent resistance to thermal expansion, making it ideal for applications in electronics, optical components, and other precision instruments.
Nilo 36 is commonly used in applications where controlled expansion is required, such as in the manufacture of electronic devices, optical mounts, and in the aerospace and automotive industries, where dimensional stability over a range of temperatures is crucial.
Features of Nilo 36:
- Low Coefficient of Thermal Expansion: Exceptional stability over temperature changes, particularly useful in high-precision applications.
- Good Strength and Toughness: Provides high strength at moderate temperatures, maintaining integrity under mechanical stress.
- Good Fabricability: Can be easily machined, welded, and formed into complex shapes.
- Resistant to Corrosion: Provides good resistance to corrosion in various environments, especially at high temperatures.
- Stable Performance: Maintains dimensional stability, making it ideal for applications in optical and electronic systems.
