Product Parameters

4J32, also known as Alloy 32, is a nickel-iron-cobalt alloy. This alloy is renowned for its excellent thermal expansion properties,
which make it ideal for use in hermetic sealing applications, especially in industries where a precise match to the thermal expansion
of glass or ceramics is required. 4J32 is widely used in aerospace, electronics, and telecommunications for components that need
high strength and stability under extreme conditions.

Characteristic
1. Controlled Thermal Expansion:
4J32 offers a coefficient of thermal expansion closely matching that of glass and ceramics, making it ideal for sealing applications.
2. High Strength:
The alloy provides excellent mechanical strength and maintains integrity under high temperatures and stress.
3. Excellent Corrosion Resistance:
Offers resistance to oxidation and environmental degradation, ensuring long-term durability.
4. Ease of Fabrication:
4J32 is easily machinable, weldable, and formable, allowing for a wide range of applications.

Product Application

Application
1. Electronics: Hermetic seals for transistors, diodes, and integrated circuits.
2. Aerospace: Sealed connectors, sensors, and components exposed to extreme temperatures.
3. Telecommunications: Microwave components, oscillators, and high-frequency devices.
4. Industrial: High-performance sealing applications, including glass-to-metal and ceramic-to-metal seals.

This powder is produced in spherical form, which makes it highly suitable for applications like additive manufacturing (3D printing),
thermal spraying, and powder metallurgy. Its spherical shape ensures excellent flowability and packing density, which are critical for
precision manufacturing processes.
