Product Overview – K93600 / K93601 / 4J36 Alloy

K93600, K93601, and 4J36 are low-expansion Nickel-Iron alloys, typically containing around 36% Nickel and the rest Iron. They are known for their low coefficient of thermal expansion (CTE), making them ideal for precision applications where dimensional stability across temperature variations is critical. These alloys are commonly used in glass-to-metal seals, ceramic-to-metal seals, and high-precision industrial applications where dimensional changes with temperature need to be minimized.

These alloys, specifically K93600 and K93601, are widely used in industries such as aerospace, electronics, telecommunications, and medical devices, as well as precision instruments and measurement systems.

Key Features:

• Nickel Content: Approx. 36%

• Low Thermal Expansion: CTE ~ 1.2 × 10⁻⁶ /°C

• Dimensional Stability: Excellent stability at varying temperatures

• Magnetic Properties: Ferromagnetic at room temperature

• Corrosion Resistance: Performs well in many environments

• High Strength: Strong mechanical properties, suitable for high-precision applications

• Weldability & Machinability: Can be welded and machined with ease

• Ideal for Sealing Applications: Used for glass-to-metal and ceramic-to-metal seals

Typical Applications:

These alloys are used where low thermal expansion and dimensional stability are essential. Some of the primary applications include:

Precision alloys are metal materials with special physical properties (such as magnetic, electrical, thermal and other properties). The vast majority of precision alloys are based on ferrous metals, and only a few are based on non-ferrous metals. Usually include magnetic alloys (see magnetic materials), elastic alloys, expansion alloys, thermal bimetals, electrical alloys, hydrogen storage alloys (see hydrogen storage materials), shape memory alloys, magnetostrictive alloys (see magnetostrictive materials), etc.
