Iron nickel Alloy Bars High Temperature Alloy
Iron-nickel alloys, often referred to as INVAR or KOVAR, are known for their excellent thermal stability and low thermal expansion coefficients. These properties make them suitable for high-temperature applications, such as in aerospace, electronics, and precision instruments.
Key Characteristics
Composition: Typically, these alloys consist of iron and nickel in varying proportions. For instance, INVAR has about 36% nickel, while KOVAR contains approximately 29% nickel and is often used for sealing glass to metal.
High-Temperature Resistance: Iron-nickel alloys can maintain their mechanical properties at elevated temperatures, making them ideal for applications that experience thermal cycling.
Low Thermal Expansion: These alloys exhibit minimal expansion when heated, which is crucial for components that require high dimensional stability.
Machinability: They can be machined easily, allowing for precise fabrication of components.
Corrosion Resistance: Depending on the specific alloy, they can offer good resistance to oxidation and corrosion.
Applications
- Aerospace Components: Used in engines and structural parts that must withstand high temperatures.
- Electronic Devices: Employed in connectors and substrates where thermal stability is critical.
- Precision Instruments: Ideal for measuring devices that require high accuracy over varying temperatures.

acid solution 6. Good processability and weldability, no cracking
sensitivity after welding 7. Manufacturing certification of
pressure vessel with wall temperature of - 196-450 ℃ 8. It is
certified by NACE standard of American Society of Corrosion
Engineers (mr-01-75) to meet the highest standard level VII for
acid gas environment
Nickel Alloy 625 Metallographic structure
625 is a face centered cubic crystal structure. After holding at
650 ℃ for a long enough time, carbon particles and unstable
quaternary phase will be precipitated and transformed into stable
Ni3 (Nb, Ti) orthorhombic lattice phase. After solution
strengthening, the mechanical properties of the material will be
improved, but the plasticity will be decreased.
