Product Description
Invar 36 Iron-Nickel-Cobalt Expansion Alloy Wire
Material Overview
Invar 36 (UNS K93600 / Werkstoff 1.3912) is a nickel-iron low-expansion alloy containing 36% nickel. This specialized material maintains an exceptionally low coefficient of thermal expansion from cryogenic temperatures up to approximately 260°C, making it ideal for precision applications requiring dimensional stability across temperature variations.
Key Characteristics
- Excellent corrosion resistance in dry ambient conditions
- Low thermal expansion coefficient: 0.6×10⁻⁶/K (20-50°C)
- Density: 8.1 g/cm³
- Melting point: 1430°C
- Available in wire (0.1-9mm), bar (11-200mm), and strip formats
Industrial Applications
- Liquefied gas production, storage, and transportation systems
- Temperature regulation devices operating below 200°C
- Aperture masks and precision optical components
- Structural frameworks for cryogenic environments below -200°C
- Scientific instruments requiring thermal stability
