Chemical Properties
The 1J50 Iron Nickel Alloy Rod exhibits reliable chemical stability in mild environments, making it suitable for applications with low to moderate corrosive exposure. Below are its key chemical properties:
- Mild Acid Resistance: The 1J50 Invar Rod shows good resistance to dilute acids, such as 3-5% sulfuric or hydrochloric acid, with minimal surface etching after short-term exposure.
- Alkali Resistance: It performs exceptionally well in alkaline environments, resisting degradation in solutions like 5% sodium hydroxide, even with prolonged contact.
- Neutral Environments: The alloy maintains integrity in neutral settings, such as freshwater or atmospheric conditions, with negligible corrosion rates.
- Environmental Limitations: The 1J50 Iron Nickel Alloy Bar is not recommended for highly acidic (e.g., concentrated acids) or saline environments (e.g., seawater), as these can lead to pitting or surface corrosion without protective coatings.
For applications involving aggressive chemical exposure, consult our technical team to explore coating options or alternative alloys.
Things to Note (Limitations)
When using the 1J50 Iron Nickel Alloy Rod, consider the following limitations to ensure optimal performance:
- Elevated Temperatures: Prolonged exposure to temperatures above 450°C may degrade magnetic permeability and mechanical properties, limiting its use in high-heat applications.
- Harsh Corrosive Environments: The 1J50 Invar Rod is not suitable for prolonged exposure to highly acidic, saline, or marine environments, as it may experience surface corrosion without protective coatings.
- Mechanical Overworking: Excessive cold working or deformation can reduce the alloy’s magnetic performance, so minimize heavy forming during fabrication.
