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

1. 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.

2. High-Temperature Resistance: Iron-nickel alloys can maintain their mechanical properties at elevated temperatures, making them ideal for applications that experience thermal cycling.

3. Low Thermal Expansion: These alloys exhibit minimal expansion when heated, which is crucial for components that require high dimensional stability.

4. Machinability: They can be machined easily, allowing for precise fabrication of components.

5. 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.
