Product Description
4J36 Alloy High Expansion Invar 36 Alloy With Precise Thermal Control Capabilities
Product Overview
4J36 alloy, also known as Invar 36, is a nickel-iron alloy notable for its low coefficient of thermal expansion. Composed primarily of iron (Fe), nickel (Ni), and cobalt (Co), with manganese (Mn), this alloy exhibits minimal expansion or contraction over wide temperature ranges, making it ideal for applications requiring precise dimensional stability.
Key Features
- Thermal Expansion: Very low coefficient of thermal expansion for dimensional stability in precision instruments
- Mechanical Properties: Excellent machinability with weldability and solderability for versatile fabrication
- Electrical Resistivity: Moderate electrical resistivity suitable for electrical applications
- Curie Temperature: Approximately 450°C for stable magnetic properties across temperature ranges
